The seals affixed to this equipment indicate that only authorized service technicians are allowed to open the equipment and perform maintenance work so that safe and troublefree operation of the equipment is ensured and the warranty remains in effect. If the seal is broken, this will result in forfeiture of all claims under the manufacturer s warranty. Important Note to Users Make sure to carefully read and follow sections marked with this symbol. They contain important safety instructions. Before you begin to weigh, please read the following directions carefully. In this way, you will avoid making any operating errors which could result in damage to the weighing platform. Working with the mass comparator requires a smooth, uninterrupted technique. After initially connecting your mass comparator to AC power (or after a relatively long power outage), allow at least 12 hours warmup time before operating the equipment. Before connecting or disconnecting peripheral devices (such as a printer) to or from the interface port on the display and control unit, make sure to disconnect the mass comparator from power. Installation Instructions Ambient Conditions Your Sartorius mass comparator is designed to provide reliable weighing results under normal ambient conditions. Set up the mass comparator in a conditioned room kept at a constant temperature (maximum allowable fluctuation: DT < ±0.5 K/h), free of drafts and aggressive agents. The humidity in the room should be between 50% and 55% (maximum allowable fluctuation: <10%). During a weighing operation, avoid moving around in the room where the mass comparator is set up. 5

6 Select a suitable place of installation for the mass comparator: C Set up the mass comparator on a stable, even surface (e.g. a Sartorius balance table) Do not expose the mass comparator to heat radiation generated, for example, by direct sunlight, light fixtures or heaters. Protect the mass comparator from drafts that come from open doors or windows or from air conditioning units. Avoid exposing the mass comparator to any vibration during weighing. Protect the mass comparator from aggressive chemical vapors. Do not expose the mass comparator to extreme moisture over long periods. Moisture in the air can condense on the surfaces of a cold mass comparator whenever it is brought to a substantially warmer place. If you transfer the mass comparator to a warmer area, make sure to condition it for about 2 hours at room temperature, leaving it unplugged from AC power. Avoid static electricity at the place of installation Use suitable materials for the floor covering, upholstery, operators clothing and tools. You can adapt the mass comparator to ambient conditions by setting the respective codes in the operating menu (for details, see Operating the Mass Comparator ).

Tighten the screws on the connectors. Place the weighing pan (25) on the weighing platform. Leveling the Weighing Platform Using the Level Indicator At the place of installation, level the weighing platform using the leveling feet (2) so that the air bubble is centered within the circle of the level indicator. To level the weighing platform, proceed as follows: To raise the weighing platform, extend the leveling feet (turn clockwise) To lower the weighing platform, retract the leveling feet (turn counterclockwise) Connecting the Mass Comparator to AC Power The mass comparator is powered by the AC adapter supplied. Make sure that the voltage rating printed on this unit is identical to your local line voltage. If the voltage specified on the label or the plug design of the AC adapter does not match the rating or standard you use, please contact your Sartorius office or dealer. Plug the AC adapter into the socket (22) at the back of the display and control unit (24). Then plug the AC adapter into the wall outlet. 7

8 Note: Use only original Sartorius AC adapters. Use of AC adapters from other manufacturers, even if these units have a registered approval rating from a national testing laboratory, requires the consent of an authorized Sartorius service technician. Safety Precautions The AC adapter rated to Class 2 can be plugged into any wall outlet without taking any additional safety precautions. The pole of the output voltage is connected to the housing of the display and control unit, which can be grounded for operation. The data interface is also electrically connected to the housing of the weighing platform (ground). Selecting the Voltage When you use the portable AC adapter model with a standardized European plug, you can select the desired voltage (see Accessories ). Note: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to Part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to correct the interference at his own expense. Changes or modifications not expressly approved by Sartorius AG could void the user s authority to operate the equipment. 8

9 I/. Operating the Mass Comparator Warmup Time Once you set up the mass comparator at its place of use, allow at least 12 hours acclimation time. After initially connecting your mass comparator to AC power (or after a relatively long power outage), the system will need to warm up for at least 2 hours before you can operate it. CF Turning the Display On and Off (Standby Mode) To turn the mass comparator display on or off, press the e key (16). F1 F2 TARE Self-test > After the mass comparator has been turned on, an automatic self-test of the mass comparator s electronic circuitry is performed. At the end of the self-test, either 0.00 g or is displayed, depending on the model. You can now begin weighing. Calibrate/adjust the weighing platform before performing the first weighing operation (see Calibration/Adjustment below). 9

10 CF F1 Mass Comparator Display The display shows the following special codes for your information: <O> means standby > The display was turned off using the e key (16) and is currently in standby mode. The mass comparator is ready to operate and does not need to warm up. F2 TARE <b> means busy > Once you switch on the mass comparator, the b symbol is displayed until you press a key. > During operation, the b symbol indicates that the mass comparator processor is still busy processing a function and cannot accept another command to perform any other functions at this time. TARE CAL > Press and hold the t key (11) and press the f key (7) to initiate the external calibration/adjustment function (see also the chapter entitled Calibration/Adjustment ).

12 Calibration/Adjustment Purpose Calibration technically means to determine the difference between the weighing instrument readout and the actual weight on the platform to determine the accuracy. Calibration does not entail any modification of the calibration weight value stored in the mass comparator. Adjustment is the correction of the difference between the measured value displayed and the true weight (mass) of a sample, or the reduction of the difference to an allowable level within maximum permissible error limits. During calibration, the mass comparator is adjusted to changes in the ambient conditions. Calibrate/adjust your mass comparator at the place of installation: after each warmup period before the first weighing operation following a change in ambient conditions each time the mass comparator is set up in a different area Use only calibration weights of an accuracy equal to or better than the particular accuracy class of your mass comparator. See the section entitled Accessories for an overview of the calibration weight sets available. You will need calibration weights of the following accuracy classes: Model CC30002 CC50002 Weight (g) 1x x20000 Accuracy class E2 E2 Tare the mass comparator when the display has stabilized. Press and hold the t key (11) approx. 2 seconds > The Application display shows C.E. ( calibration: external ), and the function display shows CAL. Press f (7) to initiate the calibration routine; the calibration weight (10000 or g) is displayed. Center the calibration weight on the weighing pan. > The mass comparator is calibrated automatically. At the end of calibration, the calibration weight value is displayed with the weight unit and an acoustic signal is emitted. Note: You can also enter the conventional weight of your calibration weight via the numeric keys to adjust the sensitivity of the mass comparator more precisely. To do this, press f (7) (CAL) to display the currently valid calibration weight. Now you can enter the desired weight value using the numeric keys. Press f (7) again (STO) to store the weight value; the previous value is overwritten. Center the prompted weight on the weighing pan. The value you entered is stored automatically. If the error code Err 02 is displayed, this indicates an error or disturbance in starting the calibration procedure. In this case, press t briefly and then, when the display shows a zero readout, press the f key again. Note: Press and hold the f (7) key to store the values in non-volatile memory. Blocking the Calibration/Adjustment Functions You can block these functions by setting code

13 I/. General Directions for Working with the Mass Comparator Working with the Mass Comparator Working with the mass comparator requires a steady hand and a smooth, uninterrupted technique. Perform a few trial weighing procedures before you begin the actual mass comparison sequence, to get a feel for the handling method required. > The weights and the mass comparator should remain next to one another in the weighing room for an extended period to condition them to the same temperature. Place the weight gently on the weighing pan. Moisture or warmth from your hands can cause measuring errors. For best results, wear gloves or use weight handles or forceps while working with the mass comparator (see Accessories ). Always place the weight in the middle of the pan. If the weight is not centered, this may result in systematic deviations in the weighing results which can influence the accuracy of your measurement unnecessarily, resulting in longer response times. General Directions Press the e key (16) to turn on the mass comparator Center your reference weight on the weighing pan Calibrate/adjust the mass comparator if necessary > After a brief period, a readout appears on the display. Press the t key (11) to set it to 0.00 g. If the displayed value changes after you have set it to zero, tare the mass comparator again. If the display continues to change, make sure you are observing the instructions given in the section entitled Working with the Mass Comparator. Remove the reference weight from the weighing pan. Place your test weight on the weighing pan. > After a brief period, the display shows the difference between the reference weight and the test weight with the respective plus or minus sign. Read off the weighing result after the mass comparator has stabilized. Note: Weighing with a mass comparator is a method of measuring by comparison, known as comparative weighing. The known mass of a reference weight is compared to the mass of the test weight, in a two-part weighing procedure. The difference in mass is shown in the weight display (13) along with the respective plus or minus sign. With full range mass comparators you can perform comparison weighing in any range, up to the maximum capacity. 13

14 Weighing Methods For accurate results, we recommend using the A-B-B-A or A-B-A method, whereby the difference in mass between test weight (B) and reference weight (A) is determined repeatedly and the average of the individual weighing results is calculated from the mean value of the measured differences. A-B-B-A Method Place the reference weight (A) and the test weight (B) alternately on the weighing pan in the sequence shown below, maintaining a smooth, steady pace: A B B A A B B A A B B A etc. 1st cycle 2nd cycle 3rd cycle etc. A-B-A Method Place the reference weight (A) and the test weight (B) alternately on the weighing pan in the sequence shown below, maintaining a smooth, steady pace: A B A B A B A B A etc. 1st cycle 2nd cycle 3rd cycle etc. Please note when using either of these methods: The time intervals between A-B and B-A or between B-B and A-A should always be the same. This produces a smooth, steady working rhythm. Note: Always lift the weight completely off of the weighing pan. 14

15 Data Interface Connecting Electronic Peripheral Devices Before you connect a peripheral device (such as a printer or PC) to the interface port: Make absolutely sure to unplug the mass comparator from AC power - also before disconnecting a peripheral device from the mass comparator data interface (20). > To document measurements with a Sartorius printer, connect the printer to the interface port (20). You do not need to adjust any settings. Re-connect AC power. To print or output data, press the p key (9). For details on the data interface (such as the data output or input formats, pin assignment, etc.), see the Interface Description included with your mass comparator. Connecting Devices to the Mass Comparator Note: The data interface is electrically connected to the mass comparator housing. The accessory cabling supplied is shielded and electrically connected on both ends to the cases of the connectors. This electrical connection may result in interference caused by ground loops or by transient currents if you have grounded the housing or connected the protective grounding conductor for AC power. If necessary, connect an equipotential bonding conductor to the mass comparator. If you have any problems with your mass comparator, please contact your nearest Sartorius Service Center. 15

16 I/. Care and Maintenance Service Regular servicing by a Sartorius technician will extend the service life of your mass comparator and ensure its continued weighing accuracy. Sartorius can offer you service contracts, with your choice of regular maintenance intervals ranging from 6 months to 2 years. Cleaning Before cleaning the mass comparator, unplug the AC adapter from the wall outlet (mains supply). Please do not use any aggressive cleaning agents (solvents or similar agents). Instead, use a cloth which has been wet with a mild detergent (soap). Make sure that no liquid enters the mass comparator housing. After cleaning, wipe down the mass comparator with a soft, dry cloth. Note: If you clean the mass comparator with water that is too hot or too cold, the difference in temperature between the water and the equipment can cause condensation to form within the equipment. This condensation can lead to malfunctions in the equipment. Safety Inspection If there is any indication that safe operation of the mass comparator with the AC adapter is no longer warranted, turn off the power and disconnect the equipment from AC power immediately. Lock the equipment in a secure place to ensure that it cannot be used for the time being. Safe operation of the mass comparator with the AC adapter is no longer ensured when there is visible damage to the AC adapter the AC adapter no longer functions properly the equipment has been stored for a relatively long period under unfavorable conditions (such as extreme humidity) In this case, notify your nearest Sartorius Service Center or the International Technical Support Unit based in Goettingen, Germany. Only service technicians who are authorized by Sartorius and who have access to the required maintenance manuals are allowed to perform maintenance and repair work on the equipment. Instructions for Recycling the Packaging To ensure safe shipment, your mass comparator has been packaged using environmentally friendly materials. After successful installation of the mass comparator, you should return this packaging for recycling.

27 ISO/GLP-compliant Printout or Record Application: Use of the mass comparator as a test and measuring instrument in quality assurance systems in compliance with the requirements of ISO, GLP, GMP and EN (European Standards) in which proof of the mass comparator s accurate performance is required. The mass comparator can record all completed calibration or adjustment operations and print out data in compliance with the requirements of Good Laboratory Practice (GLP). The mass comparator, interfaced with a data printer or a computer, generates documentation that includes the date, time, serial number and model designation, which means data can be unambiguously traced to the mass comparator that generated it and the time at which it was generated. Select the ISO/GLP-compliant printout or record mode by setting the corresponding code in the operating menu. ISO/GLP-compliant printout/record mode Off * Only for calibration/adjustment and linearization functions Always on The following menu code setting must be selected in order to obtain an ISO/GLP-compliant printout/record: With data ID codes Important Note: ISO/GLP-compliant printouts/records are not generated when the factory setting, menu code 7 2 1, is active. With the Auto print data output parameter selected (code or 6 1 5), only calibration/adjustment and linearization data is output. 27

28 Printout/Record for Calibration/Adjustment Functions A printout or record is generated at the end of the following functions: all calibration and adjustment procedures all linearization procedures The printout can have the following lines: MC1 - Sartorius : Manufacturer Model CC50002 : Mass comparator model S/N : Serial number of the mass comparator Id : ID number (e.g., for entering a workstation or operator ID) Date : 24 May 02 : Current date Start: 10:05:30 : Time at which the application started Cal. : Test : Calibration mode (in this case, sensitivity test ) Diff.: g : Weighed value for sensitivity test Cal. : External : Type of adjustment function (in this case, external calibration ) Stat.: Complete : Status of adjustment/calibration or linearization function End : 10:05:45 : Time application ended Name : : Field for signature of the operator responsible Set. : g : Calibration weight value (only for external calibration ) Reset: Undoing All Menu Code Changes The reset function lets you undo all menu code changes, which means the original factory defaults (marked by an asterisk ( * ) in this manual) are restored. This can be useful if, for example, you do not know which menu codes have been changed. Reset function Reset all codes 9 1 Off 9 2 * 28
