5 With this Sartorius Balance, you have acquired a high-quality electronic weighing instrument that will ease your daily workload. Please read these Installation and operating instructions carefully before you begin to operate your new balance. In "Part l: Installation and Operating Instructions," it is assumed that you are using the factory-set menu codes. Warranty Do not miss out o n the benefits of our full warranty. Please complete the warranty registration card, indicating the date of Installation, and return the card to your Sartorius Office or dealer. 4

6 Storage and Shipping Conditions Allowable storage temperature: +5 C C +41 F F The packaging has been designed to ensure that the balance will not be damaged even if it is dropped from a height of 80 cm (about 32 inches). After unpacking the balance, please check it immediately for any visible damage as a result of rough h and 1during shipment. lf this is the case, proceed as directed in the section entitled "Safety inspection." Save all parts of the packaging and the box for your balance to avoid damage during transportation. You may ship your balance only in the complete original Standard packaging supplied. Before you pack your balance, unplug all connected cables to prevent damage. Do not expose the balance unnecessarily to extreme temperatures, moisture, shocks, blows or vi brat Ions. Transporting the Balance To transport the balance, lift it by the housing base using both hands. Do not lift it by the display unit or by the draft shield! 5

7 Equipment Supplied The equipment supplied includes the components listed below: Balance Power supply Weighing pan Shield disk Protective ring Interior weighing chamber draft shield (depending on the balance model) 2 draft shield covers Dust cover for the draft shield and balance housing Dust cover for the display unit 6

8 Installation Instructions Ambient Conditions Unfavourable ambient conditions may affect the weight readouts. Therefore, choose a suitable place to set u p your balance. lt should not be exposed to the following: Extreme heat radiation Drafts Extreme- vibrations Aggressive chemical atmospheres Set up your balance on a sturdy fable or on a wall console (see "Accessories" in "Part l): Product Data Sheet"). Do not expose the balance to extreme moisture over long periods. Moisture in the air can condense on the surfaces of a cold balance whenever it is brought to a substantially warmer place. lf you transfer the balance to a warmer area, make sure to condition it for about 2 hours at room temperature, leaving it unplugged. Afterwards, if you keep the balance connected to AC power, the continuous positive difference in temperature between the inside of the balance and the outside will practically rule out the effects of moisture condensation. You can adapt the balance to your specific requirements and to the ambient conditions simply by changing the code settings in the balance operating menu. For more information, turn to "Part III: Balance Operating Menu." 7

9 Getting Started Place the components listed below inside the weighing chamber one at a time in the Order given: - shield disk (8) - weighing pan (7) - protective ring (6) - interior weighing chamber draft shield (depending on the balance model) (5) Place the small draft shield cover (2) on top of the semi cylindrical interior draft shield door (4). Adjusting the Exterior Draft Shield Element The draft shield consists of two semi cylindrical dements, one of which functions as a door. Turn the exterior draft shield element (3) by the riffled part on the bottom to the position you desire, That way, you will have the opening located exactly where it is most convenient for you. When adjusting the exterior element, be sure to shield the weighing chamber from you r breath and the warmth of your hands (see diagram on the left in addition). Depending on your application, you can define the menu code so that the inferior draft shield door (4) is opened by motor or by hand (see pp. 14). Adjusting the Swivel-Mounted Display Unit Move the swivel-mounted display unit (11) around the base of the draft shield to adjust it to the position you desire (+/- 85 ). 8

10 Connecting the Balance to Line Voltage The balance is energized by a power supply. Make sure that the voltage rating printed o n this unit is identical to your local line voltage. lf the voltage specified on the label or the plug design of the power supply does not match the rating or Standard you use, please contact your Sartorius Office or dealer. The power supply is suitable for installation as stationary equipment. To use a main feeder cable from the ceiling or to mount a CEE plug, you will have to make arrangements inside your facilities for installation of such cable equipment by a certified electrician. Important Note Use only original Sartorius Power Supplies identified by the Sartorius label. Use of power supplies from other manufacturers, even if these units have an approval identification marking from a national testing laboratory, requires the consent of an authorized Sartorius service technician. To operate your balance using an external rechargeable battery, pack, see "Accessories" in "Part II: Product Data Sheet.". Detailed information on additional options for powering the balance is available in our Service Information bulletin, no. 15/88 (fore example, using local! extralow voltage). Plug the cord of the power supply into the AC jack on the balance, Then insert the plug of the power supply in a wall outlet. 9

11 Safety Precautions The power supply rated to Class 2 can be plugged into a wall outlet without taking any additional safety precautions. The pole of the Output voltage is connected to the balance housing, which can be grounded for Operation. The interface (see "Interfacing Devices" on page 28 in addition) is also electrically connected to the balance housing (ground). Information on Radio-Frequency Interference: Warning! This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause interference to radio communications. It has been tested and found to comply with the limits for a class A computing device pursuant to Subpart J of Part 15 of FCC rules, which are designed to provide reasonable. protection against such interference, when operated in a commercial environment Operation of this equipment in a residential area is likely to cause interference, in which case the user at this own expense will be required.to take whatever measures may be required to correct the interference. Connecting Electronic Devices (Peripherals) Make sure to unplug the balance from the power supply before you connect or disconnect a peripheral device (printer or PC) to or from the interface port. Safety Precautions 10

12 Information on Weighing Electro statically Charged Samples Problems with static electricity can occur in environments with low humidity. To avoid these problems when you use your balance in such an area, wipe down the entire draft shield on both the inside and outside with a commercially available antistatic agent. In addition, the glass draft shield interior has a conductive coating. There is a terminal (15) for connecting an equipotential grounding conductor to the frame (housing) on the rear side of the balance. This is used for additionally grounding a peripheral device connected to the balance (for example, a vibrating spatula). The terminal is designed for single grounding wires up to.25" Standard gauge or 6 mm 2 - and for.18" Standard gauge or 4 mm 2 stranded wires. lf you need to use electro statically charged glass or plastic Containers with a relatively large diameter, you should utilize our antistatic pan (155 mm see "Accessories" in "Part II: Product Data Sheet"). Levelling the Balance Using the Level Indicator At the point of use, level the balance using the levelling feet (9) so t hat the air bubble is centered within the circle of the level indicator (10). To level the balance.using the level Indicator as a guide: Extend the levelling feet (turn clockwise) to lift the balance. Retract the feet (turn counter clockwise) to lower the balance. 11

13 How to Operate the Balance After initially connecting the balance to line power (or after a relatively long power outage), allow for at least 2 hours' warmup. Working with the Research Series Balance requires a smooth, uninterrupted technique. The weight display shows the following special codes for your information: OFF The balance was disconnects from line power (power failure or outage; the balance was reconnected to line power). 0 (standby) The display has been turned off by the key (27), and the balance is now in the ready-to-operate mode and does not require warmup. (busy) Once you turn on the balance, the symbol is displayed until you press a key. During Operation, this symbol indicates that the balance processor is still busy processing s function and will not accept any other commands to perform functions at this time. CAL I The balance has internal calibration weights and can be calibrated with the key (for the "Quick-CAL function, see also page 22)., R1 or R2 The number in the R code identifies the particular weighing range you have selected. Symbol for the application selected (in this case, the weighing mode and toggling among the weighing ranges). 12

14 Important Note lf the symbol flashes, this means that the balance wants to self-calibrate. You do not need to interrupt your weighing procedure, because the balance will wait until it detects that you have stopped weighing for one complete minute. Afterwards, the balance will perform fully automatic infernal calibration. The symbol will flash until the balance Starts this fully automatic procedure on its own or until you activate one of the calibration functions by pressing a key (see p p. 22). Turning the Display On and Off (Standby Mode) Press the key (27) to turn the display on or off. Self-Test After the balance has been turned on, an automatic self-test of the balance's electronic circuitry is performed, and the draft shield closes automatically. It ends with a readout of " g" or " g" (depending on your balance model or the display mode selected). Important Note for Automatic Operation with a Robot To be on the safe side for automatic Operation of the -balance with a robot, you should turn off the fully automatic draft shield function (see "Part III: Balance Operating Menu"). Otherwise, if a power outage occurs and the balance is automatically restarted, the robot arm may accidentally hit the draft shield as it is closing. 13

15 Opening and Closing the Draft Shield Door If you are loading small objects, open the draft shield only as far as is absolutely necessary for your application. This reduces the amount of draft so your balance will stabilize faster than it normally would when the draft shield is wide-open. You have several options for operating the interior draft shield door (4): Semi-Automatic Mode (Aperture Angle s 170 ) Press one of the keys labeled (22) to have the draft shield door opened or closed by motor. The interior draft shield door moves slowly the first time it is opened after connecting the balance to AC power. Semi-Automatic with an Aperture Angle of 10 to 140 By a "self-teaching function," the draft shield door can "learn" to open automatically to a user-defined aperture angle from 10 to 140 : To define this angle, move the interior draft shield door (4) to the desired Position. 14

16 Press the key (22] to have the draft shield door closed by motor. While closing, the door moves slowly. The previously adjusted aperture angle is stored in the process. Now if you press the key (22) again, the draft shield door will open at a faster speed to the Position you selected. You can load and remove a tare container with a diameter exceeding the aperture angle, without having to change the stored aperture setting. To do so, press the key (22) for approx. 2 seconds. This will cause the draft shield door to open automatically as far as it will go (170 ). You can always change the aperture angle by manually adjusting the position of the draft shield door. lf you want the draft shield door (4) to open completely (170 C) after you press the key, just open the door manually as far as it will go. Important Note The aperture angle remains stored even after you have turned off the display u sing the key. A stored aperture setting will not be erased until you unplug the balance from AC current. Manual Mode Of course, you can also open and dose the draft shield door (4) by hand. 15

17 Weighing Place your sample on the weighing pan (7) to determine the weight, and dose the draft shield door (for example, by pressing the key (22). Do not read off the weight indicated in the display (18) until the weight unit (in this case g or a different unit selected - see "Part III: Balance Operating Menu"} appears as the stability symbol. Taring lf you wish to use a Container or if the weight display does not indicate g or g (depending on the particular balance model you are using, or on the display mode selected), zero the display before You weigh. To do so, press the tare control (24). During taring, you can have the fully automatic draft shield function either on or off. To shorten work procedures; and make them easier, you should have this fully automatic function o n active Status. In this case, after you press the tare control, the draft shield door will dose, the balance will be tared, and the draft shield door will re-open. For more information on turning this function on or off by menu code, refer to "Part III: Balance Operating Menu." 16

18 Weighing Range Structure SuperRange - "SingleWide-Range Balance" (identified by S in the model designation RC...S) SuperRange models have an extraordinarily high resolution, i.e., the weighing range has a resolution ranging u p to a few million digits. There is one level of fine readability for the entire weighing range [for example: 0.01 mg). DualRange (identified by D in the model designation RC...D) 2 weighing ranges; a fine range and a Standard range The balance automatically)' switches from the fine range which is 10 times more accurate (for example: 52 g capacity - readability of 0.01 mg) to the Standard range (for Instance: 210 g capacity -01 mg readability} when the balance is loaded beyond the fine range limit (>52 g). The weight readout is displayed with the readability of the Standard range until you tare in the fine range (load <52 g). PolyRange (identified by P in the model designation RC...P). -Wide weighing range with multiple levels of accuracy In the PolyRange balance, the weighing range is divided into as many as 3 ranges, each with a different readability. In the various ranges, the readability will adjust so that the last numeral of a 'weight readout is displayed with a resolution of 1, 2 or 5 digits. After you press the tare control (24), you will obtain the highest possible resolution, even when the balance is loaded. 17

19 Weighing in the IQ-Mode (Load-Dependent Readability) In the IQ-Mode (IQ = Intelligently quick), weighing is done with a loaddependent readability of 0.01 % (for different settings, see "Part III: Balance Operating Menu') throughout the entire weighing range of the balance. The display resolution of the last digit changes in increments of 1, 2, 5, 10, 20, etc. in proportion 1o the weight of a sample. Oftentimes, a display accuracy of 10 milligrams is sufficient for a load of approx. 110 g. In this case. it makes sense to select weighing range R 1 with an accuracy of 0.01 o/a by pressing the toggle key (25). While you are filling u p to a target weight. it is certainly easier to work with a target of g than with an absolutely accurate readout of 110.1S885 g. By selecting the IQ-Mode for automatic adaption of the display accuracy, you will obtain stable weight readouts even faster. In daily laboratory routines, analyses must often be performed with a certain accuracy. The IQ-Mode meets this requirement - on a semi-microbalance, it gives you the full accuracy of all 5 decimal places for initial sample weights below 1 g; whereas for heavier samples (of 100 g or more), it provides lower readability which is sufficient: Initial sample weight Below 1 g Above 100 g readout 0,98756 g 123,13 g 18

20 Mass Unit Conversion by Toggling You can have the weight displayed in grams or milligrams. To select the three weighing ranges one after the other, press the (25] each time. toggle key In addition to grams and milligrams, this balance gives you a wide variety of other menu-definable international weight unit options. For more information, refer to "Part III: Balance Operating Menu." 19

21 Calibration and Linearization During calibration, the balance is adapted to changes in ambient conditions. You should recalibrate your balance each lime you set it up in a different area or when the ambient conditions change (fore example, temperature or barometric pressure). When these conditions are constant, the balance should be calibrated once a day. To meet the highest requirements for accurate weighing, we recommend that you calibrate the balance before each weighing series. Make sure that the draft shield is closed before calibration or linearization Starts. You can abort any calibration or linearization procedure by pressing the key (28), The balance offers you various calibration and linearization functions. The function you select is indicated in the display by one of the following special codes;»calicalic.i.c.t.l.i.c.e.«the balance has built-in calibration weights and can be calibrated with the key ( Quick-CAL" - see page 22) The calibration or linearization function is activated Internal calibration Calibration test Linearisieren intern Eternal calibration 20

22 Fully Automatic Calibration lf the symbol flashes, this means that the balance wants to self--calibrate. You do not need 1o interrupt your weighing procedure, because the balance will wait until it detects that you have stopped weighing for one complete minute. Afterwards, the balance will perform fully automatic internal calibration. During this procedure, the draft shield should be closed 1o ensure that calibration is done correctly. The symbol will flash until the balance Starts this fully automatic procedure on its own o r until you activate one of the calibration functions by pressing a key (sees next page). The balance can perform fully automatic internal calibration two hour after it has been connected to line power or once the temperature has changed by ±1.5 degrees since the last calibration process. Independently of these factors, the balance can perform a fully automatic calibration after four hours at the latest. To turn off the fully automatic calibration function by menu code, refer to "Part III: Balance Operating Menu." In the fully automatic mode, the draft shield closes after pressed. or the tare control is 21

23 INTERNAL CALIBRATION Quick-CAL Function using the key: Unload the pan, close the draft shield and tare. When the balance displays a zero readout, press the key (20). "C" will now be displayed.

In this case, tare and then press the key again when a zero readout appears. An acoustic Signal indicates the end of calibration. Internal Calibration Using the Tare Control: Calibrate the balance using the tare control if an application program (such as the tare memory) is assigned to the key by menu code in the balance operating menu (see Parts III and IV). Press the tare control (24) for at least 2 seconds until "C.l." and "CAL are displayed (next to the key). Unload the pan, make sure the draft shield is closed, and tare. When the balance displays a zero readout, press the key (20). C" will now be displayed. The built-in calibration weights are internal by applied by servomotor and removed at the end of calibration. If external interference affects the calibration procedure, you may obtain a brief display of the error message "Err 02." In this case, tare and then press the key again when a zero readout appears. An acoustic signal indicates the end of calibration. 22

24 EXTERNAL CALIBRATION Use only calibration weights that have tolerances equal or better than those of accuracy class E2 (for 200 g -> ±0.3 mg). Press the tare control (24) for a1 least 2 seconds until "C.l." and CAL are displayed (next to the key). Important Note lf you press the key (20) when "C.l." is displayed, this will activate the internal calibration function. For "external calibration" press the key (21) until "C.E." is displayed. C.E. Stands for "external calibration." Unload the balance, make sure the draft shield is closed, and tare. Press the key (20) when a zero readout is displayed. Afterwards, the calibration weight readout will be indicated. lf external interference affects the calibration procedure, you may obtain a brief display of the error message "Err 02." In this case, tare and then press the key again when a zero readout appears. Center the calibration weight on the weighing pan and dose the draft shield door. An acoustic Signal indicates the end of calibration. 23

25 CALIBRATION TEST Rather substantial changes In barometric pressure and temperature may affect t he display response of these highly accurate Research Series balances. To ensure that you obtain the full accuracy of these balances, even when you use the entire weighing range, we have implemented a calibration lest function. It will help you decide whether o r not you need to recalibrate your balance (for example, to maintain the same accuracy during long-term weighing series). Press the tare control (24) for at least 2 seconds until "C.l." and "CAL" are displayed (next to the key). key (21) twice until "C.t." is dis- Select the calibration test by pressing the played. Unload the balance, make sure the draft shield is closed and tare. "C.t." Stands for calibration fest. When the balance displays a zero readout, press the key (20). The built-in calibration weights are now internal by applied by servomotor. Afterwards, the deviation of the momentary weight readout from the target weight (displayed in grams only) is indicated. lf external interference affects the calibration test procedure, you may obtain a brief display of the error message "ERR 02." In this case, tare and then press the key again when a zero readout appears. Important Note The balance should be recalibrated if the deviation of the readout from zero exceeds the tolerance of the calibration weights used (accuracy class E2 ± 0.3mg). -key (20): The balance automatically calibrated (see also page 21).) or -key (21): Quits the calibration test An acoustic Signal indicates the end of the calibration test. 24

Stands for "internal linearization." When a zero readout is displayed, press the key (20). C will now be indicated. The built-in weights are internally applied one after the other by the Servomotor, and the weighing range is automatically liberalized. lf external interference affects the linearization procedure, you may obtain a brief display of the error message "Err 02." In this case, tare and then press the key again when a zero readout appears. An acoustic signal indicates the end of linearization. Important Note The balance automatically self-calibrates after each internal linearization procedure. 25

27 Data Interface lf you wish to record weight data using a Sartorius Data Printer or process them using "Data Control," plug the printer connector into the interface port (14} of the balance. You do not need to adjust any settings! Remove the protective cap from the data interface port. Caution! Make sure to unplug the balance from the power supply before you connect or disconnect a peripheral device (printer or PC) to or from the interface port. To print data on hard copy or Output them on the screen o1 an on-line Computer, press the key (23). For information on special data output Parameters, se-e "Utilities" under "Part III: Balance Operating Menu." During data Output, you can have the fully automatic draft shield function either on or off. To shorten work procedures and make them easier, you should have this fully automatic function on active Status. In this case, after you press key, the draft shield door will dose, the balance will output data, and the draft shield door will re-open. For more information on turning this fully automatic draft shield function on or off by menu code, refer to "Part III: Balance Operating Menu." 26

28 Interfacing Devices with the Balance Please note that the interface port is electrically connected lo the protective grounding conductor of the balance housing. The interface cables supplied as Standard equipment are shielded, and both ends of each cable are electrically connected to the connector cases. This connection may result in interference caused by ground loops o r by transient currents if you have grounded the housing or connected the protective grounding conductor for line power. If necessary connect an equipotent bonding conductor to the balance 27

29 Below-Balance Weighing A port for a below-balance weighing hanger is available on the bottom of the balance. To fasten the hanger, open the below-balance port by removing the two screws on the bottom of the balance and detaching the closing plate. Now you can attach a sample using a Suspension wire, for example. Common applications for below-balance weighing include specific gravity determination or immersing a sample in a special atmosphere (medium for reaction). You can also use the M2 thread to attach a sample. Important Note When you use such below-balance weighing hangers, you must install a shield to eliminate drafts.. How to Fasten the Antitheft Locking Device To fasten the antitheft locking device, use the lug (16) located on the rear panel of the balance. At the place of installation, secure your balance with the lock. 28

31 Care and Maintenance Before cleaning the balance, unplug the power supply from the wall outlet. Cleaning the Balance Housing and the Draft Shield Please do not use any aggressive cleaning agents (solvents or similar agents]. Instead, use a piece of lint-free cloth which has been wet with a mild detergent. Clean the semi cylindrical elements of the draft shield with a commercially available glass cleaning agent. Make sure that no liquid enters the balance housing. After cleaning, wipe down the balance with a soft, dry piece of cloth. Cleaning the Weighing Chamber Keep the draft shield base plate from becoming too dirty: Carefully remove spilled powder from the weighing chamber by using a small vacuum cleaner (such as a small car vacuum cleaner with a mini-hose attached). Afterwards, remove the weighing pan (7] and the shield disk (8) from the weighing chamber. Vacuum out the remaining powder from the weighing chamber using the same equipment described above. Do not clean the weighing chamber by blowing off powder from the parts! To remove liquid spills, use blotting paper. 30

32 Safety Inspection lf there is any indication that safe Operation of the balance is no longer warranted. turn off the power and unplug the balance from the power supply immediately. Lock the balance and the power supply in a secure place lo ensure that they cannot be used for the time being. Safe Operation of the equipment is no longer ensured when there is visible damage 1o the power supply the power supply no Ionger functions properly the power supply has been stored for relatively Ion g periods under unfavourable conditions In this case, notify your nearest Sartorius Service Center or the International Service Support Department based in Goettingen, Germany. Only service technicians who have access to the required maintenance manuals are allowed to perform maintenance and repair work on the equipment. We recommend that the balance together with the power supply be inspected by a qualified Sartorius service technician according to the following checklist; Insulation resistance >7 megohms measured with a constant voltage of at least 500 V at a 500 kohm load Equivalent leakage current <0.05 ma measured by a property calibrated multimeter The duration and number of measurements should be determined by a qualified Sartorius service technician according to the particular ambient and operational! conditions for the power supply. Such inspection should be done at least once a year. 31

44 How to Access the Menu The Sartorius MC1 Balance can do much more than "just weigh." It can "think" in various units of measure, adapt to unfavourable conditions and process weight data for a variety of applications. In the operating menu, you can define how your balance will adapt to ambient conditions and also how it will work to meet your special requirements. For your convenience, the menu codes have been factory-set so that you do not have to make any changes if you want to "just weigh," and if your balance will be operated under normal ambient conditions. To select specific functions, you will need to set the respective menu code. This code tells the microcomputer inside the balance what it has to do to meet your requirements. Here is a short example to help you understand how to set a menu code. Just take a look at the picture below. See the apple on one of the trees? Now if you want to explain to somebody where this apple is located, you could number the trees, the main branches and the small branches according to a certain pattern. Then you could describe the location like this: the apple is on tree no. 3, main branch no. 1 and small branch no. 4. To express this as a menu code, you'd say: Now that s easy enough, isn't it? 3

45 The areas where certain code settings are found in the balance/scale operating menu are designated similarly to the way in which the location of the apple is pinpointed. Going back to our example, tree no. 3: The apple is located exactly where the unit symbol "ct" is on our menu "tree." On main branch no. 1, you'll find all weight units for the second weighing range which you select with the toggle key small branch no..4, carats - "ct" is defined as the weight unit - so your code will be On The weight unit "g" for grams is on the same tree (3) and the same main branch (1 ), but on small branch no. 2. Therefore, the code for grams is The code for pounds (lb) is 3 1 5, and so on. (For a list of codes, see "Overview of the Weight Units," column for the "2nd range," on page 14.) At this point, you'll probably want to know how to change the menu codes stored in your balance. Go right ahead and try to change a few of the menu code settings. That s the best way to familiarize yourself with the performance capabilities and the versatility of the microcomputer in your Sartorius Balance. Don't worry! Even if you've selected the "wildest" codes and totally thrown off all the code settings you need, all you have to do is press a key to set things straight again. Your balance will work just like it did when it left the factory - with the original factory-set menu codes. There are three Steps to changing a code: - access the menu - set a code - confirm and store this code To set a code, use the four keys which are defined on the display as arrow points to indicate the direction. Function Key Go back Go forward increase Decrease 4

46 Now for a little hands-on practice! It's your turn to try a setting - how about changing the weight unit in the second weighing range (use to select this range) from grams to carats (et), Code: (In our example, the 1 st weighing range " " will remain unchanged.) The balance operating menu is protected against accidental changes. That s why you'll need to "unlock" it: Change from the Status readout to -L- Stands for "list" for checking menu code settings, and -C- Stands for "change" for selecting a different menu code. In the following directions, we've included diagrams to show you what you actually see on the display and which key you need to press, for example: The text next to the diagrams tells you how to carry out each Step 5

47 Examples for Changing Menu Code Settings How to set code for "ct" in the second weighing range - Turn off the balance - Turn it back on - While all segments are displayed, briefly press the tare control - If -L- is displayed, unlock the menu access switch - Remove the protective cap located to the left of the AC jack on the rear panel of the balance, and move the switch in the direction of the arrow - Change the left-hand number to 3 - Move to the middle number - Now move from "1" to the right-hand number (When you move to the righthand number, the previously set numeric code will appear.) - Change the right-hand number to 4 - Confirm the code setting Important Note: You must press the tare control in order to.confirm the code you have just set: This is indicated by the "o" after the code. - Press to store your menu code setting 6

48 That s all there is to it! Now, if you press the key, you can read the weight in carats "ct": Of course, you'll be in the IQ-Mode, with a load-dependent readability of 0.01%, as defined by the factory-set menu code. You say you don't like it? You'd rather weigh in the unit "ct" with the highest possible accuracy down to the last digit? No problem! Just set the appropriate code: (You'll find this code listed under "Display Modes" on page 16.) How to set code for full resolution in the second weighing range - Turn off the balance - Turn it back on - While all segments are displayed, briefly press the tare control - Change the left-hand number to 3 - Move to the middle number - Change the middle number to 2 - Move from "2" to the right-hand number (When you move to the right-hand number, the previously set numeric code will appear.) - Change the right-hand number to 1 7

49 - Confirm the code setting Important Note: You must press the tare control in order to.confirm the code you have just set: This is indicated by the "o" after the code. - Press to store your menu code setting Now you can read the weight in "ct" accurately down to the last digit. Congratulations! You've just finished the two examples we've given to help familiarize you with how to use the code setting function. Remember, the keys labelled,,,, and have special functions in this mode: and = Move to the left and right, respectively and = Respectively increase and decrease a number by one = Confirms a code setting = Stores a code setting and leaves the menu n the application programs, the and keys will have other functions determined by the program that you have selected. The particular function assigned is always shown on the display next to each key for easy identification. Before you begin to look for different menu codes in the description of the application programs, you should try out the reset function to undo all changes in order to see how it works. 8

50 How to Undo All Menu Code Changes - Reset Function The reset function lets you undo all menu code changes, which means that you will obtain the original factory-set menu codes so that your balance will operate according to them. To use this function, you will need to select code How to set code: Turn off the balance - Turn it back on - While all segments are displayed, briefly press the tare control ( ) - Change the left-hand number to 9 - Move to the middle number For this code, the middle number is skipped. Instead, you will always obtain the right-hand number. - Change the number to 1 - Confirm the code setting Important Note: You must press the tare control ( )to confirm the code you have just set: This is indicated by the "o" after the code. - Press to store your menu code setting All menu code settings are now the ones which were originally set at the factory. 9

51 Note: The actual menu code setting in the balance operating menu is identified by a small "o" after the last number. When you access the operating menu, the previously set numeric code will be displayed after you select the left and the middle numbers, which means the entire menu code setting is displayed. This makes it easy for you to check the menu code settings. Please do not forget to relock the balance operating menu. The "-L-" indicates that it is currently locked: You can lock the menu anytime you wish once you have accessed it. However, it is best if you wait until you have changed the last code setting. To use the locking function, make sure code is set in the balance operating menu. If code is set, the menu access switch will not lock. In this case, "-C-" will be displayed whenever you access the menu: The lists on the next pages give just a small sampling of the code options available for the balance operating menu. These options involve Standard balance Operation, utilities for printouts or data transfer, and additional functions. lf you would like to change several menu code settings, you do not have to press operating menu. / after each change to leave the balance For your convenience, we've indicated all factory code settings with an "*." You'll find information on the application programs in "Part IV." A quick-reference guide listing all menu code options for the "Standard" operating parameters of the balance is given in the section starting on page 34. This guide also provides space for you to enter any changes to the menu codes. 10

52 Balance Operating Parameters How to Adapt the Balance to Ambient Conditions To adapt your balance to ambient conditions, you may need to change the response time (see the Product Data Sheet). Code Very stable conditions Stable conditions * Unstable conditions Very unstable conditions Standard Weighing Mode - Manual Filling Mode You can optimally adapt your balance to meet either of these requirements. In the manual filling mode, the display compensates for fluctuations of the load on the balance so that you obtain a steadier readout. Standard weighing mode * Manual filling mode Code Stability Range The stability range in digits works together with the stability symbol (unit symbol). When the stability symbol is displayed, the weight readout is stable within the defined range. Readout is stable within ± Code 0,25 digit ** ,5 digit digit digits * digits digits * = Factory setting ** = Setting not available for balances with 0.01 mg readability 11

53 Stability Symbol Delay This setting allows your balance to compensate for individual interfering factors which slowly subside, such as turbulent air currents generated within the weighing chamber. Code No delay Short delay * long delay Extremely long delay Tare Parameter You can define when the balance will perform the taring Operation: At any time not until the readout is stable * Code Auto Zero Function When this zero tracking function is activated, any changes off of the zero readout that are equal to a defined fraction of digits per second are automatically tared. In other words, it ensures a stable zero. Auto Zero on * Auto Zero off Code * = Factory setting 12

54 Weighing in Three Ranges The toggle key lets you switch back and forth among three weighing ranges. lf the menu code is set for three ranges, press the key each time to toggle to a different range. How to Select the Number of Ranges Code Block the key Two weighing ranges Three weighing ranges * lf two or three weighing ranges are defined by menu code, the ID displayed for the particular range just selected will change as follows: ID displayed 1 st range 2 nd range 3 rd range Two weighing ranges R1 R2 Three weighing ranges **) R1 R2 Weight Units The "initial weight unit" is the unit in which your balance will weigh the moment you turn it on. This unit is defined in the 1 st range. You can select a different unit for each weighing range by setting the appropriate menu codes. Important Note: You can select almost any weight unit; however, this may entail a loss of resolution, since the number of places which can be displayed is limited (e.g., if you select "kilograms.") * = Factory setting **) The weighing range available when the balance is on is identified only by the scale symbol. 13

55 Overview of the Weight Units: Symbol Code 1 st range 2 nd range 3 rd range Grams o Grams g *1 7 2 * Kilograms kg Carats ct Pounds lb Ounces oz Troy ounces ozt Hong Kong taels tl Singapore taels tl Taiwanese taels tl Grains gr Pennyweights dwt Milligrams mg * Codes 1 7 1, and are reserved for programming special units to meet the needs of customized applications. The Standard, factory-set unit is grams. In the display, you will see "o" as the stability symbol for a stable readout, just as for kilograms. Some unit Symbols printed on hardcopy or output on a Computer screen will differ from the way they are shown on the balance display: This applies to code numbers ending with 3 = kg 6 = tlh 9 = tls 10 = tlt * = Factory setting 14

56 IQ-Mode (Load-dependent readability) In the IQ-mode, weighing is done with a menu-definable, load-dependent readability throughout the entire weighing range of your balance. In the process, the display resolution of the last weight digit changes in increments of 1, 2, 5, 10, 20, etc., in proportion to the weight of the sample. Oftentimes, a display accuracy of 10 milligrams is sufficient for a relatively heavy load. In this case, it makes sense to select the 2nd weighing range (identified as "R 1" for 3 ranges) with an accuracy of 0.01 % - a touch of the toggle key is all it takes. In the second weighing range (codes through ), a load-dependent readability of 0.01% has been factory-set. While you're filling up to a target weight, it is certainly easier to work with a target of g than with an absolutely accurate readout of g. By selecting this function for automatic adaption of the display accuracy, you will obtain stable weight readouts even faster. In daily laboratory routines, analyses must often be performed with a certain level of accuracy. The IQ-Mode meets this requirement - on a semi-microbalance, it gives you all 5 decimal places for initial sample weights below 1 g; whereas for heavier samples of 100 g or more, it provides proportionally lower readability which is usually sufficient: Initial sample weight Readout (for a code setting of 0.01 %) Below 1 g g Above 100 g g This mode for adapting the display accuracy enables you to weigh with constant proportional precision between 1 % and 0.01% over the entire weighing range of your balance. The particular accuracy you choose is indicated in the top right corner of the application display field. Select the load-dependent display accuracy independently for each of the three weighing ranges. Load-dependent display accuracy Code 1 st range 2 nd range 3 rd range 1.0 % % % % % % % * * = Factory setting 15

57 Display Modes You can select the display mode that best meets your individual requirements. The menu code settings for all weighing ranges are listed on the next page. Final Readout Mode "- -" lf you are only interested in the final readout, you can select this mode by setting code A special symbol "- -" will be displayed in any weighing range until the final stable readout appears in digits. For the Standard readout mode, set code (all readouts in digits). Readout mode Code Special symbol for unstable readings when load changes Standard digital readout mode * Last Numeral Blanked When the Load Changes As the load on your balance changes, the display resolution is reduced by a factor of 10 so that you will obtain a faster and more stable readout. In the process, the last numeral is blanked until the load stabilizes. Once the load stabilizes, the readout is shown again with the full display accuracy, which means the last numeral is displayed. Display Accuracy t You can define the level of accuracy by changing the display increments, also called "scale intervals" (of the last numeral). The display increments possible are as follows: 1, 2, 5, 10, 20, 50, etc. Starting with the basic increments of a weight unit, the display accuracy can be reduced by as many as three levels so that you will obtain a faster readout with reduced display accuracy. To make this concept easier to understand, the three levels are designated as "rounding factors" in the tables summarizing the various menu code settings. PolyRange Function (application for "single-range" balances) The PolyRange function divides a single weighing range into as many as 3 ranges, each with a different readability. In the various ranges, the readability will adjust so that the last numeral of a readout Ts displayed with a resolution of 2 or 5 increments. The PolyRange function makes filling easier because the readability becomes slightly coarser as the load increases and you will not immediately lose an entire place of readability. Press the tare control at any range level to restore the full resolution of the first range, even when the balance is loaded. Display mode Code 1 st range 2 nd range 3 rd range Highest possible accuracy Last number blanked when load changes * *3 4 2 Rounding factor Rounding factor Rounding factor PolyRange function** * = Factory setting ** = Only available for balances with the weighing range structure "SuperRange" 16

58 Calibration und Linearization Functions Select the appropriate menu code to define the access Status for each of the following calibration and linearization functions, which are activated by holding down the tare control for a few seconds: External calibration C.E. Internal calibration C.I. Calibration fest C.t. Internal linearization L.I. External linearization L.E. However, if the menu access switch is unlocked ("accessible" Status indicated by -c- after you have accessed the balance operating menu), the "external calibration" function will be accessible even though you have set the menu code for "access denied." External calibration Code Accessible * Access denied Internal calibration Code Accessible * Access denied Calibration test Code Accessible * Access denied External linearization The linearization weights to be loaded are displayed on the balance one after the other in increasing order. External linearization Code Accessible * Access denied Internal linearization Code Accessible * Access denied * = Factory setting 17

59 Multiple Calibration Mode The calibration accuracy can be increased. The calibration values calculated from the average of the individual calibration procedures. You can use the "multiple calibration mode" for both infernal and external calibration. The number of calibration procedures is indicated in the 3rd place of the application display field (e.g., "C 1 5 ). Important Note: lf "Err 04" is briefly displayed, the calibration values deviate too much from one another. This means the calibration value measured is not stored, and the calibration procedure will be repeated. Multiple calibration mode Code Off * On Fully Automatic Calibration and Linearization Automatic calibration and linearization Code Off Off (with calibration Status)* Fully automatic calibration on * Fully automatic calibration and linearization on Wait Interval until Fully Automatic Calibration Starts 1 minute after stability * minutes after stability Code * = Factory setting * = The symbol " " flashes in the display until you press the appropriate key to activate one of the calibration functions. 18

60 Quick CAL with You can activate the "internal calibration" function anytime by a touch of the key (factory setting). That s why we call it "Quick CAL" for short. You can also set a different menu code to change the function of the key from "internal calibration" to "calibration test." Both functions are accessible even if you select code or , respectively. Function of the key Code Access denied Internal calibration * Calibration test * = Factory setting 19

61 Utilities for Printouts or Data Transfer Sartorius MC1 Balances come Standard with an interface. You can plug a Sartorius Printer or a Computer into this interface port to print data on hard copy or transfer them to your Computer. Moreover, you can choose to Output data from your balance to this on-line device either automatically or by pressing the print key on the balance. The balance operating menu lets you define the various parameters for data output. For information on the data formats and for interfacing a Computer or a different peripheral device, see "Part V: Interface Description." Data Output Parameter This parameter is coupled with or without the stability parameter = stable readout or no motion is detected Print on request = data is output only when the print key is pressed or a Software command is received Auto print = continuities. automatic data output Code Print on request regardless of stability Print on request after stability with storage of the function * Print on request after stability without storage of the function Auto print regardless of stability Auto print at stability Automatic Data Output You can stop and Start automatic data output by pressing the print key. To avoid operating errors or to ensure that data will be output continuously in the automatic mode, you can block this function Start/stop auto print using the print key Auto print not stoppable * Code * = Factory setting 20

62 Data Output at Defined Intervals You can reduce the volume of data in the "auto print" mode by defining the interval at which data will be Output automatically. This auto print interval is based on the number of times the display is updated. Auto print interval Code 1 display update * display updates display updates display updates display updates display updates display updates Automatic Taring after Data Output This convenient setting lets you checkweigh a series of samples or products without having to unload the balance after each weighing Operation. This means less work for you: the sample remains on the pan after the weight readout has been printed or transferred to an on-line Computer the balance is tared automatically after the weight readout has been printed or transferred to an on-line Computer you simply load the next sample or part Automatic taring after data output Code Data output without automatic taring * Data output with automatic taring Data ID Codes To help you identify weights, piece counts, percentages, etc., a code letter is printed or displayed in front of these values. For example, an "N" printed or displayed before a weight value identifies it as a net weight. You will find the data ID codes of a particular application program listed in the corresponding description. This ID code increases the data Output format from 16 to 22 characters for each weight readout. ID code for data output Code Without * With * = Factory setting 21

63 Additional Functions A number of additional menu codes enable you to assign or deny access to various functions. Menu Access Function You can define the function of the menu access switch by setting the code for the balance operating menu to "accessible." In this setting, "-C-" will be displayed on your balance whenever you access the menu. This means that you can change the menu codes at any time regardless of the setting the menu access switch. Access to the balance operating menu Code Accessible depends on setting of menu access switch * Beep Tone (Acoustic Signal) lf you wish, you can turn off the beep tone (i.e., "acoustic Signal"). Acoustic signal Code On * Off Blocking the Keys You can block all keys on the balance (except for ). Key function Code Accessible * Blocked * = Factory setting 22

64 Analog Display: Bar Graph/Marker In the factory setting, the analog display works as a bar graph: By changing the menu code, you can turn the analog display completely off or have it appear as a marker. When the marker is selected, two individual Segments will move within the display scale range to indicate the loading Status of your balance. Analog display Code Off Bar graph * Marker Power-On Mode Depending on the operating mode, - line current, battery Operation or continuous Operation -, you can change the power-on mode of your balance. The factory setting is: (power) off on standby. In the setting "toggle between on and standby," the balance power will turn back on automatically after a power failure has occurred, or after you have disconnected your balance temporarily from line current. In the setting "automatic power-on," the balance will turn back on automatically after a power failure has occurred; after the balance has been disconnected from line current; or after the key has been pressed. In this setting, the balance can no longer be turned off by the key. Power-on mode Code (power) off on standby * on standby Automatic power-on Display Backlighting Depending on your individual workplace requirements, you can turn the display backlighting on or off accordingly: Display backlighting Code On * Off * = Factory setting 23

65 Fully Automatic Draft Shield Function You can define the fully automatic draft shield function to meet the most diverse requirements in order to shorten work procedures and make them easier. After you have pressed a function key (or after a control command has been received see "Part V: Interface Description"), the draft shield will dose automatically and the balance will then perform the particular function activated by the key. lf code or is set, the draft shield will open once the function selected has been performed. In code setting or , the last numeral is displayed when a balance with 0.01 mg readability is turned on. To be on the safe side for automatic Operation of the balance with a robot, you should turn off the fully automatic draft shield function (code ). Otherwise, if a power outage occurs and the balance is automatically restarted (e.g., code or 8 6 4), the robot arm may accidentally hit the draft shield as it is closing. The draft shield operates automatically for the following functions: powering on the balance ( key) taring once the balance has stabilized (tare control ) printing on request after stability ( key) starting the calibration function ( key) using the tare memory once the balance has stabilized ( key) - see also "Part IV: Application Programs" storing weights during over/under checkweighing ( key) - see also "Part IV: Application Programs" storing weights while weighing in percent and counting ( key) - see also "Part IV: Application Programs" Automatic draft shield function Code Off Close draft shield perform function after stability open draft shield Close draft shield perform function with stability symbol delay open draft shield Close draft shield perform function after stability * Close draft shield perform function with stability symbol delay Important Note For calibration, make sure to press the key to dose the draft shield. * = Factory setting 24

66 Display Accuracy with the Draft Shield Automatically Opened or Manually Adjusted You can define the display accuracy for the automatically opened or manually adjusted draft shield by changing the increments, also called "scale intervals" (of the last numeral). The display increments possible are as follows: 1, 2, 5, 10, 20, 50, etc. Starting with the basic increments of a weight unit, the display accuracy can be reduced by as many as six levels so that you will obtain a faster readout with reduced display accuracy (convenience feature for weighing-in). To make this concept easier to understand, the six levels are designated as "rounding factors" in the tables Code Highest possible accuracy * Rounding factor Rounding factor Rounding factor Rounding factor Rounding factor Rounding factor IQ-Mode with the Draft Shield Automatically Opened or Manually Adjusted (Load-Dependent Readability) In the IQ-Mode, weighing is done with a menu definable, load-dependent readability throughout the entire weighing range of your balance. In the process, the display resolution of the last weight digit changes in increments of 1, 2, 5, 10, 20, 50, etc., in proportion to the weight of a sample. While you're filling up to a target weight with the draft shield open, it is certainly easier to work with a target of g than with an absolutely accurate readout of g. By selecting this function for automatic adaption of the display accuracy, you will obtain stable weight readouts even faster. The IQ-Mode enables you to weigh with constant proportional precision between 1 % and 0.01 % throughout the entire weighing range of your balance. Load-dependent display accuracy Code Off * % % % % % % % * = Factory setting 25

67 GLP/GMP Print or Record The Research Series Balance can record all completed calibration operations and print out data in compliance with the requirements of Good Laboratory Practice (GLP). The balance, interfaced with a Data Printer or a Computer, creates a document that records the date, time, serial number and model number which makes it possible to clearly trace data to the balance that generated it and the time at which it was generated. Application: Use of the balance in quality assurance Systems in areas subject to compliance with GLP/GMP. Select the GLP/GMP printout/record mode by setting the appropriate code in the menu of the balance operating program. GLP/GMP printout/record Code Off * Only for calibration functions Always on The following are menu code settings which must be selected in order to receive a GLP/GMP printout/record: Auto. output of reference %/qty and reference weight or Auto. output of reference weight only and With data ID code Important Note: GLP/GMP printouts/records will not be Output if the factory setting or "without data l D code" is selected.

82 In addition to the functions implemented strictly for weighing, Sartorius Balances of the MC1 generation offer you a variety of application programs to handle tough daily routine work in the laboratory as well as in industrial plants. lf you have not yet experienced how fast and accurately a Sartorius Balance can count parts or convert weights into percentages, now is a good opportunity to try it out. In this description, you'll find a few simple examples for the following applications: Tare Memory Weighing in percent Over/under checkweighing Counting You can also use these programs in combination. How? You'll discover the ins and outs in the examples described on the next pages. To select an application program or a specific function, set the appropriate code in the menu. Part III describes in detail how to set menu codes. For quick information on setting these codes, see page xyz in this manual for brief instructions. Additional settings for running the particular program and displaying or printing the data on hard copy are listed in a fable of codes. One thing you should do when you want to set the code for a different program, or when someone else has already operated the balance is: Select the reset function - code to change all menu codes back to the original factory settings. 3

This means you will have all functions of the combined program available in addition. Program Tare memory Over/under checkweighing (net weight) Over/under checkweighing (difference in weight) Code * = Factory setting 11

91 Over/Under Checkweighing This program is used to check whether products are within a specific tolerance range, to sort and classify items, and to fill and batch products. Symbols are displayed above the bar graph as visual aids for this type of program: the equal sign indicates the target weight; the minus sign, the underweight limit; and the plus sign, the overweight limit. Within the tolerance range, the response sensitivity of the bar graph is increased. You can define the tolerance limits between 0.1 % and 10% as required. To find these setting options, see the chart on page 24. The factory setting is for tolerance limits of +/- 1.0 % For checkweighing, you can choose between two programs: checking net weights - code checking variations in weight - code These programs enable you to checkweigh in any range that can be selected with the toggle key labeled. Instead of weights, you can use percentages or piece counts for checkweighing if you have selected the corresponding application program by menu code. You will find examples of these in the section dealing with checking net weights. Both programs provide four control lines via the balance interface, which are called data output port lines. This means you can interface a remote display unit that has colour-coded indicators, which are activated by the lines depending on the target weight and the tolerance limits selected. For more information, see the "Interface Description" in Part V. You can use the Sartorius Three-Segment Checkweighing Display Unit, model YRD10Z, as a visual aid during checkweighing. 12

99 Breaking Bulk/Portioning Code A weight readout is Stored as the reference sample quantity (factory setting: 10 pcs), although it is shown with a negative sign. To change this value, see the description on page 21. While counting (piece count readout), you can Update the reference sample by pressing identified by - OPT - (approx. double the reference sample quantity) if the average reference piece weight is too light. In the process, the reference weight is recalculated based on the total reference sample weight and the piece count displayed. Additional menu codes used in the example: Function Code As an alternative, you can select With data ID code this output parameter: Ref. quantity + ref. wt Reference weight Application: breaking bulk/packaging the same quantities Step/(key ld)/key Readout Data output/printout Load Container with small parts g, g Remove 10 parts and place in 1 st package; store as ref. sample: STO REF g - 10 pcs nref + 10 pcs wref g Fill package up with the number of parts required pcs Qnt pcs 0 pcs Remove 750 parts; fill 2nd package pcs 0 pcs Continue as directed above The data ID codes mean nref wref Qnt pcs g 750 pcs reference sample quantity (piece count) reference sample weight calculated piece count 20

108 General Information This description is written for users who wish to connect their Sartorius Balance to a Computer or a different peripheral device using a V24/V28-RS232C(-SD/423 interface. By using an on-line Computer, you can change, activate and monitor the functions of the balance and the application programs. Sartorius Balances of the MC1 generation come with a V24/V28-RS232C(- S)*)/423 interface as a Standard feature. You can plug an external remote-control switch into the data interface port to activate these functions: print (data transfer), open/close the draft shield, F1 or F2 key function, or tare. The data interface also provides data output port lines for various application programs. lf you interface an original Sartorius accessory device, such as a Sartorius Data Printer or a similar unit, with a balance that has the factory-set menu codes, you do not need to change any settings. *) = Sartorius pin assignment 3

110 Data Output Formats Depending on the menu code setting: = no data ID code or = data ID code, data will be output with either 16 or 22 characters. For a data output of 22 characters, a 6-character ID, as defined in the application program selected, precedes the 16 characters. Data Output Format with 16 Characters Display segments that are not activated (+ or - sign, leading zeros other than zeros before the decimal point) are output as spaces. The following data block formal is output according to what is displayed on the balance: * * * * * * * * * * * * CR LF E E E * * * * * * * * = Space, E = Unit 5

111 When data are Output without decimals, the decimal point is suppressed (except when a certain display mode is selected) * * * * * * * * * * * CR LF E E E Data output example: g * g * * CR LF Characters: 1 st Plus or minus sign or space 2 nd 10 th Weight with a decimal point; leading zeros = space 11 th Space 12 th 14 th Unit symbol or space 15 th Carriage Return (CR) 16 th Line Feed (LF) lf the weighing System has not stabilized, no unit symbol is Output. For the display formal parameter "last numeral off or only at stability" (blank last numeral by a rounding factor of 10 or display last numeral when the readout is stable), the 10th character in the string is a space. The reason: the last numeral without a decimal point is not blanked. Instead, it is given a definite zero, otherwise the display would go completely blank when the balance is unloaded. In this case. you will obtain the Standard display formal. Unit symbol (standard balance): * * * No stability parameter t l s Singapore taels g * * Grams t l t Taiwanese taels k g * Kilograms g r * Grains c t * Carats d w t Pennyweights l b * Pounds m g * Milligrams o z * Ounces % * * Percent o z t Troy ounces p c s Pieces (parts) t l h Hong Kong taels 6

112 Special Codes are output only if the menu code 6 1 1, or is set (see "Part III: Data Output Parameters"). Special status-dependent codes * * * * * A B * * * * * * * CR LF The following Status codes are Output for "A B": * * : Tare H * : Overload C * : Calibrate *) L * : Underload : All numerals shown in stable readout Special error-dependent codes * * * E R R * X Y Z * * * * CR LF X = *, 0, 1, or 2 as a one-place error code Y Z = two-place error index code *) The displayed Status code "C" will also be Output when a print command is received. 7

113 Data Output with ID Code (Menu Code 7 2 2) When data with an ID code is Output, the ID code consisting of 6 characters precedes the data with a 16-character formal. During data Output, all characters are shifted to the right by 6 characters nd character K K * K * K * K * K * V * X * X * X X X X X X X * E * E * E CR LF V = Plus or minus sign * = Space x = Digit E = Unit. = Decimal point K = Letter for an ID comment CR = Carriage return LF = Line feed When special codes are Output (only if menu code 611, 614 or 615 is set), the letters "Stat" for Status code are assigned to the 1 st through the 4 th characters of the data string. Status-dependent string: nd character S t a t * * * * * * * * A B * * * * * * CR LF Error-dependent string nd character S t a t * * * * * E R R* * X Y Z * * * * CR LF A, B = Status codes X = *, 0, 1 or 2 as a one-place error code YZ = two-place error index code 8

114 Data lnput Formats Commands can be input via the balance interface port to control the balance and application program functions. Control commands are distinguished according to those with upper-case letters or special characters and those with lower-case letters. Format for Control Commands Control commands can include up to 13 characters. Each character must be transmitted with a start bit, a 7-bitASCII-coded character, a parity bit and one or two stop bits. You can define the parity, baud rate and handshake mode, including the number of stop bits, by programming the codes in the balance operating menu (see page 18). Formats: ESC K CR LF ESC K X CR LF ESC K X X X X X X X CR LF ESC = Escape K = Command character X = Number. = Decimal point _ = Underline CR =Carriage Return LF = Line Feed The characters CR and LF do not have to be transmitted in the data string. 9

115 Control Commands with Upper-Case Letters or Special Characters ESC P CR LF Print ESC Q CR LF Acoustic signal ESC S CR LF Self-test ESC T CR LF Tare ESC Z CR LF Internal calibration ESC = CR LF Internal linearization The commands "P" through "=' do not affect the code settings of the balance operating menu. The command S causes the processor to reinitialize (turns the balance off and back on again). The balance will operate according to the commands available up until the processor is reinitialized. Once the balance has been turned on, the processor will always recognize the codes entered by the user in the balance operating menu. ESC O CR LF Block keypad ESC R CR LF Release keypad Adaptation to Ambient Conditions ESC K CR LF Very stable ESC L CR LF Stable ESC M CR LF Unstable ESC N CR LF Very unstable 10

116 Control Commands with Lower-Case Letters All functions that can be selected by pressing the appropriate keys on the balance can also be activated by commands. Standard: ESC f 0 CR LF function key ESC f 1 CR LF function key ESC f 2 CR LF function key ESC f 6 CR LF function key ESC s 0 CR LF Info function ESC s 3 CR LF Clear function ESC x 0 CR LF Calibration test Each control command with lower-case letters (such as f, s, w and x) must be terminated by an underline (ASCII = 5F Hex). 11

117 Computer-Controlled Operation of the Draft Shield Control Commands for the Draft Shield ESC w 0 CR LF Draft shield Status (polling) ESC w 1 CR LF Open draft shield (aperture angle -170 ) ESC w 2 CR LF Close draft shield ESC w 3 CR LF Open draft shield as far as stored position (see also "Installation and Operating Instructions" in "Part l") Each control command with the lower-case letter "w" must be terminated by an underline (ASCII = 5F Hex). Draft Shield Status Polling the draft shield Status is done to control the motor-driven draft shield door. The draft shield Status will not be indicated until all movement of the draft shield door has completely stopped (draft shield motor "off"). Data Output Formats for the "Draft Shield Status" These depend on the particular menu code setting: code "no data ID code" = data Output with 16 characters or code "with data l D code" = data Output with 22 characters Data Output Format with 16 Characters * * * * * * W * 0 X X Y Y Y CR LF * = Space Data Output Format with 16 Characters With this format, the ID code "Stat" is Output in the 1 st through the 4 th places S t a t * * * * * * * * W * 0 X X Y Y Y CR LF * = Space 12

118 The draft shield Status consists of control codes and the turning angle of the draft shield. The control codes are identified as XXX, and the turning angle is designated as YYY XX = Control Codes for the Draft Shield The decimal values of bits 0 through 6 are added for the following control codes and Output as a decimal number: Decimal value Binary value Control code Bit 0 = 0 Bit 0 = 1 Bit 1 = 0 Bit 1 = 1 Bit 2 = 0 Bit 2 = 1 Bit 3 = 0 Bit 3 = 1 Bit 4 = 0 Bit 4 = 1 Bit 5 = 0 Bit 5 = 1 Bit 6 = 0 Bit 6 = 1 No control error Control error Draft shield motor "off" Not implemented Not implemented Motorized draft shield, as far as it will turn "Self-teaching'' function off "Self-teaching" function on (aperture angle 10 to 140 ) Open draft shield*) Closed draft shield*) Slow speed*) Fast speed*) Motorized draft shield Operation Manual draft shield Operation "Control Error" The control code for "control error" is Output if the draft shield door has not reached the selected position after one attempt (for mechanical reasons). "Speed" The draft shield door moves slowly in the following cases: during the first motor-driven draft shield movement once the balance has been turned on while closing after you have entered an aperture angle from 10 to 140 in the manual mode ("self-teaching" function) while opening following one unsuccessful attempt to reach the selected position (for mechanical reasons) For all other functions, the draft shield door moves rapidly. *) These control codes refer to the previous movements of the draft shield door. 13

119 YYY = Turning Angle of the Draft Shield The movements of the motorized draft shield door are output as a 3-place decimal number with a position readout. The readout 000 to approx. 170 corresponds to 0 (closed) to 170 (completely open). Turning Angle The draft shield door has opened by approx. 170 o Control Codes 0 Bit 6 motorized draft shield operation + 32 Bit 5 fast speed + 0 Bit 4 open draft shield + 0 Bit 3 self-teaching off + 4 Bit 2 draft shield door turned as far as possible + 0 Bit 1 draft shield motor off + 0 Bit 0 no control error = 36 14

120 Synchronization and Data Output Parameters Definition During data communication between the balance and an on-line device (Computer), "telegram-style" information consisting of ASCII characters is transmitted by the interface. For error-free data communication, the interface parameters including the baud rate, parity and handshake mode, as well as the character formal, must be the same for both units. You can change these parameters in the balance operating menu so that they match those of the on-line device. In addition to these parameter settings, you can define the data Output parameter of the balance so that data are transmitted depending on various conditions - for more information, see "Part III: Utilities." lf you do not plug a peripheral device into the interface port on the balance, this will not generate an error message. In this case, data will be Output but not received. Handshake The balance interface (Sartorius Balance Interface = SBI) has a 23-byte transmit buffer and a 40-byte receive buffer. You can access the balance operating menu to define various handshake parameters: Software handshake: controlled by "XOFF" and "XON" Hardware handshake: - after "CTS" send 2 characters -after "CTS" send 1 character What happens when you define a Software handshake? Receiving device: "XOFF" will not be transmitted until the receive buffer has stored the 26th character. The enable command "XON" is given after the buffer has transmitted all characters up to the 14th character. 15

121 lf the device addressed does not understand the control command, the SB! receiving device continues to operate additionally with a hardware handshake after it has received another 6 characters. For data communication with a Software handshake, "XON" must be sent by a device when it is turned on in order to enable another on-line device to exchange data. Sequence: Transmitting device Receiving device (balance) byte byte byte <XOFF> byte (Once <XOFF> is transmitted, a maximum of byte 14 bytes can still be received.) : : : Pause : : : <XON> byte byte Transmitting device: The importance of such handshake control for data transmission becomes especially apparent - when the continuous automatic data Output parameter is defined -when data Output is controlled by application programs. Once <XOFF> is received, it prevents further transmission of characters. When <XON> is received, it re-enables the transmitting device to send data. The transmitting device is always enabled for sending data after it has been switched on. lf data transmission is interrupted by the control line (CTS) or the command <XOFF> while a data block is being Output from an application program (only for printing a section of text with several lines of data), the readout will be locked into the display at the same time. Data Output will be blocked until the interface receives an enabling Signal. 16

122 Activating a Data Output Process You can define the data Output parameter so that output is activated when a print command is received, or is activated automatically. You have two options for the automatic mode: data output can be either synchronous with the balance display or activated at defined intervals (to select the parameter, see "Part III: Utilities"). Data Output by Print Command The print command can be transmitted by a Software command or by pressing the print key. You can connect an external universal switch for remote control to the balance interface port (for the print function, see: "Part III") in addition to an interface cable for a different device. For the switch, use pins 8 and 15 of this port and a cable up to 1.5 m or 5 ft long. lf data output is requested by a Software command (see the section on "Data lnput Formats"), you can install a 15 m (50 ft) cable for RS232C or a 300 m (984 ft) cable for RS423. Automatic Data Output In the "auto print" operating mode, the data are Output to the interface port without requiring a print command. You can choose to have data Output automatically at defined print intervals with or without the stability parameter. Whichever parameter you choose, the data will be Output as the readouts appear on the balance display. lf you select the auto print setting, data will be transmitted immediately the moment you turn on the balance. Automatic data Output can be stopped and restarted either when you press the print key, or when an external print command is received, if you have set menu code These data Output functions are described in "Part III: Utilities." 17

125 Control Lines For classification or filling in the ''over/under checkweighing" application program, you can use the voltage levels of four data Output port lines to control an external on-line display or control instrument. The voltage levels of the data Output ports will change according to various patterns, depending on the reference weight and on the lower and upper weight limits. Control output 1: lighter Control output 2: equal Control output 3: heaver Control output 4: set (target) 20
