5 1.0 INTRODUCTION This manual is intended for all users of the Geosense GeoLoggers 800/1000 data loggers and provides a guide for its installation, operation and maintenance. It is VITAL that personnel responsible for the installation and use of the GeoLogger 800/1000 READ and UNDERSTAND the manual, prior to working with the equipment. 1.1 General Description The Geosense GeoLogger 800/1000 is an automatic data logging system used typically within Geotechnical & Structural instrumentation for monitoring and logging of many types and numbers of sensors with output signals such as :- Frequency Voltage Current Resistance RS-485 BUS They are built around the Campbell Scientific CR800 and CR1000 control modules and their particular features are:- Reliable long term performance Rugged; suitable for demanding environments Proven technology & components Fully reprogrammable remotely & on site Real time monitoring possible Data can be accessed remotely Various power options including solar for remote locations The Geosense GeoLogger 800/1000 is pre-assembled and configured to suit individual project requirements and will come partly programmed in accordance with customers requirements. 1.2 Theory of Operation A wide range of sensors (digital or analogue) can be connected to a Geosense GeoLogger 800/1000 which controls the sampling interval times and the storage of the output signals onto the CPU. On-board software (LoggerNet) is used to program all the settings within the unit and the data can be downloaded either directly to a PC or remotely via GSM/GPRS. Explanation of all the main components is outlined in section

8 1.4 Multiplexer (Flexi-Mux) A multiplexer is used to increase the number of sensors that can be measured with a data logger and is located between the data logger and the sensors which allows a single channel of the data logger to be sequentially connected to numerous sensors. The most common multiplexer used in the Geosense GeoLogger is the RST Flexi-Mux and can sequentially multiplex 5 groups of 4 wire inputs or 10 groups of 2 wire inputs and these settings can be changed using the Internal DIP switches. The number of sensors can be expanded by connecting (chaining) multiple Flexi-Muxs allowing the signals to cascade through the system. This allows a virtually unlimited number of sensors to be connected to a single channel. The data logger program and control ports advance the Flexi-Mux through each sensor. The Flexi-Mux is fitted with internal transient protection on each individual line which eliminates the need for external protection unlike traditional multiplexers Flexi-Mux identification Earth/ground spade terminal 2. Channel identification 3. Multiplexed terminal channel identification 4. Sensor connection ports (fitted with removable terminal blocks) 5. Modular 18-pole Mux control terminal 6. DIP switch setting illustration (switch accessed through rubber grommet on base) 7. Mounting tabs 8

9 1.4.2 Flexi-Mux connections - overview The sensors are connected into the terminal blocks (4) which are capable of taking the outputs in two different settings :- With temperature (4 pole) Without temperature (2 pole). The mode will have been configured for your individual project requirements at manufacturing stage and cannot be easily changed. Contact Geosense for advice pin Mux terminal block This is all pre-wired and therefore nothing needs to be done with this. Where multiple Flexi-Muxs are used this is where they are linked together. 4 5-pin sensor connection ports This is where all the sensor cables are wired into the Geosense GeoLogger. These 5 pin tabs are generally shipped separately. The sensor wires are easily connected and the tabs placed into position. For the wiring details for the most common types of sensors see sections to KEY THINGS TO CONSIDER WHEN WIRING Route cables away from the power supply Strip cables ~10mm Ensure shield is connected with VW Refer to labels on inside of cabinet Label each cable and reference the terminal blocks and Flexi-Muxs 9

10 1.4.7 Flexi-Mux reset The reset line is used to activate the Flexi-Mux. It is activated by a signal in the range of +2.0V to +10V DC. When this line drops lower than 0.9V DC the Flexi-Mux enters a quiescent low current drain state and the common terminals (A, B, C, D) are electronically disconnected from all the sensor input channels. Reset should always connect to a data logger control port Flexi-Mux clock Pulsing the Flexi-Mux clock line high (with reset set high) advances the channel. When the reset first goes high the common terminals A, B, C, D are disconnected from all sensor input terminals. With the Flexi-Mux set in the 4-Pole mode, when the first clock pulse arrives the common terminals are switched to connect with the sensor input channel 1 which consists of 5 wires : A, B, C, D and shield. When a second clock pulse arrives the common lines are switched to connect to channel 2. The Flexi-mux advances along the leading edge of the positive going clock pulse. The voltage level must fall below 1.5V DC and then rise above 2.0V DC to clock it. The clock pulse should be at least 1 ms long. A delay (typically 10 to 20 ms) should be inserted into the data logger program between the beginning of the clock pulse and the measurement instruction to ensure sufficient setting time for the relay contacts. Generally a control port is used to clock the multiplexer however switched excitation can also be used Earth/ground The earth terminal of the Flexi-Mux must be connected to the data logger power earth/ ground. 1.5 Modem Where remote communication is required the Geosense GeoLogger 800/1000 can be fitted with a GSM/GPRS modem to provide:- Remote access to data Remote access to re-configure the data logger Provide alarms The modem should have a 3G data enabled fixed IP SIM card to allow communication via telephone modem and IP protocol. For setting up of communication see section

11 1.6 Software LoggerNet software is used to control and schedule the data acquisition. During manufacture a program written in LoggerNet is loaded onto the Central processing unit (CPU) based on the customer/project requirements and covers:- Sensor type Sensor quantity Sampling interval timing Method of communication Alarms (if applicable) In order to communicate with the Geosense GeoLogger 800/1000 LoggerNet software will need to be installed onto a laptop/pc in order to finish configuring the unit on site together with the ability to download data and will include:- Base readings (VW sensors) Sensor identification (serial number) Sensor location (channel in Flexi-Mux) Sensor calibration factors 1.7 EMC - Electro Magnetic Compatibility EMC is the electromagnetic interaction of electrical and electronic equipment with other electrical and electronic equipment. All electronic devices have the potential to emit and be affected by electromagnetic fields. With the reduction in size of electrical components and the ever increasing amount of electrical & electronic devices such as mobile phones, twoway radios, safety control systems, signalling, generators, welding equipment, power cables etc in all environments, especially construction sites, there is a huge potential for devices to interfere with each other. Geosense GeoLoggers 800/1000 have been designed and tested for EMC under the relevant CE marking directives to comply with the highest standards including requirements set out in London Underground requirements G-222 & This ensures correct operation under the harshest of site conditions. Cables attached to a Geosense GeoLogger should have adequate shielding to minimise the affects of electrical noise (EMI) and have the correct functional earth (see section 5.2). FAILURE TO PROVIDE SUITABLY SCREENED CABLES & TOGETHER WITH EMC GLANDS COULD RESULT IN INCORRECT OPERATION OF THE EQUIPMENT ENSURE THERE IS SUITABLE FUNCTIONAL EARTHING TO ENSURE CORRECT OPERATION OF THE EQUIPMENT 11

14 4.0 DELIVERY This section should be read by all users of Geosense GeoLoggers. 4.1 Packaging Geosense GeoLoggers are packed for transportation to site. Packaging is suitably robust to allow normal handling by transportation companies. Inappropriate handling techniques may cause damage to the packaging and the enclosed equipment. The packaging should be carefully inspected upon delivery and any damage MUST be reported to both the transportation company and Geosense. 4.2 Handling Geosense GeoLoggers are precision measuring instruments. They and their associated equipment should always be handled with care during transportation, storage and installation. Once the shipment has been inspected ( see below ), it is recommended that Geosense GeoLoggers remain in their original packaging for storage or transportation. Cable should also be handled with care. Do not allow it to be damaged by sharp edges, rocks for example, and do not exert force on the cable as this my damage the internal conductors and could render the installation useless. 4.3 Inspection It is important to check all the equipment in the shipment as soon as possible after taking delivery and well before installation is to be carried out. Check that all the components detailed on the documents are included in the shipment. Check that the equipment has not been physically damaged. 4.4 Storage DO NOT DROP AS THIS MAY CAUSE DAMAGE TO INTERNAL COMPONENTS ALWAYS CHECK UNIT WEIGHT BEFORE LIFTING Geosense GeoLoggers contain electronics and whilst they are designed for outside use and mounted within a waterproof (IP66) enclosure the internal circuit board can be affected by excessive moisture, dust and temperature. When not in use they should be stored in a cool, dry location with the cabinet door closed. Most units have a sealed battery fitted and therefore this should be disconnected if not in use to avoid discharging. DISCONNECT BATTERY WHEN NOT IN USE 14

15 5.0 INSTALLATION This section of the manual is intended for all users of Geosense GeoLoggers and is intended to provide guidance with respect to their installation. It must be remembered that no two installations will be the same and it is inevitable that some fine tuning of the following procedures will be required to suit specific site conditions. 5.1 Getting started Prior to installation of a Geosense GeoLogger it is essential to establish and confirm details of the installation to be carried out. Some of the main considerations are listed below :- 1. Intended location (ideally away from moving equipment) 2. Mounting of the enclosure - wall, mounting frame or pole (to suit unit weight) 3. Cable protection 4. Power supply (mains/battery/solar) 5. Position of solar panel 6. Tools - the following is a brief list of tools typically used during the installation:- Mounting frame Drill Drill Bit Spirit Level Bolts & fasteners Set of spanners Typical mounting frame supplied by Geosense including solar panel 15

16 5.0 INSTALLATION contd Wiring The individual components of the Geosense GeoLoggers are all pre-wired so that the only wiring that is required will be:- Mains power (where applicable) Solar panel power (where applicable) Sensor cables (Multiplexer where applicable) Each GeoLogger is fitted with the following cable glands (standard or EMC type):- One for the power supply (mains or solar) One for aerial if modem fitted One for each sensor WHERE SHIELDED CABLE IS REQUIRED ENSURE THAT THE GEOLOGGER IS FITTED WITH EMC GLANDS THE BOTTOM PLATE IS FITTED UPSIDE DOWN FOR SHIPPING PURPOSES TO PROTECT THE CABLE GLANDS AND SHOULD BE REVERSED BEFORE CARRYING OUT ANY WIRING THE GEOLOGGER IS SHIPPED WITH THE BATTERY AND CPU DISCONNECTED. CONNECT IN THE SEQUENCE ADVISED Undo the 8 screws in the bottom plate and remove Re-fit the bottom plate with the dome nuts on the outside. 16

17 5.0 INSTALLATION contd Wiring contd Mains power with battery back up The unit is mains powered with a battery back up which means that it can be operated using mains only but it is recommended to have a back up in case of mains failure. The unit is supplied with the red cable + POSITIVE terminal on the battery removed to preserve the battery when not in use. Re-connect the + POSITIVE terminal. Once the battery has been re-connected the power to the CPU (logger) should now be connected by placing the green terminal block into the POWER IN socket. 17

18 5.0 INSTALLATION contd Wiring contd Mains power connection with battery back up contd... The power supply required is volt AC but this is then transformed down to 12 volt DC for the operating components. The battery is trickled charged from the mains as a back up in case of mains power The Geosense GeoLogger is supplied with the mains cable already pre-wired into the internal power transformer from 220 to 12 volt and only needs connecting to a mains supply. Undo the cable gland nut and feed the end of the power cable down through the cable gland labelled MAINS fitted on the bottom plate. Once the cable has been fed through place the rubber seal and gland nut over the cable. Push home the rubber seal and tighten the gland nut. Connect to a suitable mains supply. ONLY QUALIFIED ELECTRICIANS SHOULD CONNECT TO A LIVE SUPPLY ALWAYS DISCONNECT THE MAINS POWER BEFORE CARRYING OUT A CONNECTION 18

19 5.0 INSTALLATION contd Wiring contd Battery powered connection Where a battery only is used everything will be pre-wired so there is no wiring to be done but the following will be required:- Connect the battery Connect the CPU (POWER IN) Solar power connection The internal power cable will already be wired internally and the only requirements are:- Connect battery Feed cable out through a gland & connect to solar panel Connect the CPU (POWER IN) CONNECT BATTERY BEFORE CONNECTING TO THE SOLAR PANEL 19

20 5.0 INSTALLATION contd Wiring contd Sensor cable connections - braided cable (typically MEMS sensors) Undo the dome nut and feed the cable through the rubber seal allowing enough length to reach the required Flexi-Mux terminal Measure ~ 25mm of braid Strip off the braid, clear wrapping and any fillers to leave ~ 25mm of braid 20

21 5.0 INSTALLATION contd Wiring contd Sensor cable connections - braided cable (typically MEMS sensors) Measure ~ 10 mm along the outer sheath and mark Pull the cable back out through the gland until the mark is visible Push the cable back into the gland to the mark and tighten 21

22 5.0 INSTALLATION contd Wiring contd Sensor cable connections - braided cable (typically MEMS sensors) Remove required sensor connection port from the Flexi-Mux Strip ~10mm off the end of each of the conductor outer sheaths and bend conductors over. Place conductors into each individual terminal Replace sensor connection port in the Flex-Mux Repeat for ALL Flexi-Muxs ALWAYS ENSURE THE CABLES & CHANNEL LOCATIONS ARE CAREFULLY PLANNED AND DOCUMENTED AS THESE WILL NEED TO BE INPUTTED INTO THE SOFTWARE 22

23 5.0 INSTALLATION contd Wiring contd Sensor cable connections - foil screened cable (typically VW sensors) Undo the dome nut and feed the cable through the rubber seal allowing enough length to reach the required Flexi-Mux terminal Strip off the outer sheath, foil and Mylar to expose the four conductors and the drain wire. ELECTRICAL NOISE (EMI) Vibrating wire instruments can be affected by electrical noise which typically comes from power lines, generators, motors, transformers and arc welders. Typically spikes in the data will be observed and the cause can often be identified by looking at the time when this interference occurs e.g. starting a welder on site. One benefit of vibrating wire sensors is that when the readings are affected they are very evident and do not have any long term detrimental effect on the sensor itself. The cable has a foil shield and a drain wire which should be connected into the middle port on the Flexi-Mux to minimise this problem. 23

Remove required sensor connection port from the Flexi-Mux Strip ~10mm off the end of each of the conductor outer sheaths and bend conductors over. Place conductors into each individual terminal including the drain wire Replace sensor connection port in the Flex-Mux Repeat for ALL Flexi-Muxs ALWAYS ENSURE THE CABLES & CHANNEL LOCATIONS ARE CAREFULLY PLANNED AND DOCUMENTED AS THESE WILL NEED TO BE INPUTTED INTO THE SOFTWARE 24

25 5.0 INSTALLATION contd Connecting logger to PC The logger is connected to a PC through the RS 232 (Not Isolated) port Connect one end of the RS 232 cable into the RS 232 (Not Isolated) port on the logger Connect the other end of the RS 232 cable into the RS 232 port on a PC If the PC does not have an RS 232 port use the RS232-USB adaptor provided YOU MAY NEED TO LOAD THE DRIVERS FOR THE RS 232-USB ADAPTOR 25

26 5.4 Modem Where remote monitoring is required the GeoLogger will be typically fitted with a preconfigured COM110A* modem that allows data to be collected from a remote datalogger across the GSM cell phone network. It also allows remote access for:- Downloading data Programming the logger Setting sampling intervals Setting alarms Configure how sensors are interrogated * other modems available on request Modem antenna connection Where a modem is fitted the antenna should be located on the outside the GeoLogger enclosure. Feed through the cable gland marked ANTENNA in the bottom panel and secure into required place on the modem. The standard aerial cable comes with a 2m cable which normally allows it to be located in in a suitable location in order to receive a good signal. Should the antenna need to be located further away a longer cable is available. Please contact Geosense for advice. 30

27 5.4.2 Installing SIM card GEOSENSE SUPPLY If the SIM card has been supplied by Geosense everything will have been configured as per customer requirements and there will be nothing required to be done. SUPPLIED BY OTHERS If the SIM card is to be supplied by others then we would recommend using systems with a fixed IP address. The SIM card is installed in the COM110A modem in the slot at the aerial end of the case in a small tray that has to be ejected by pushing in the small green button which is to the right of the slot holding the tray. Use a pen or similar to push the button inwards. Insert the SIM with card with the gold contact side of the card facing upwards in the tray. Ensure the cut-out of one corner of the card is orientated to match the recess in the tray so the SIM sits flat in the tray. Push the tray back into the slot until fully in then, with the aerial connected, power on the modem and check if the LED starts flashing within a minute or so to indicate successful registration on the network. Configuration should be carried out in accordance with the COM110A manual in the Appendix. BEFORE INSTALLING THE SIM MAKE SURE POWER IS DISCONNECTED FROM THE MODEM 31

28 6.0 DATA ACQUISITION SOFTWARE 6.1 Introduction The main operation of the Geosense GeoLogger is determined by the LoggerNet software which is already loaded onto the CR800 or CR1000 CPU. However the Geosense GeoLogger has been hardware preconfigured and is provided partially pre-programed to collect data from all channels generally in accordance with customers requirements. Where no preference has been provided the Geosense GeoLogger 800/1000 is set to log and store readings at hourly intervals. The Geosense GeoLogger is shipped with the clock set to UST/GMT, and the battery disconnected. Re-connect the battery before operation. 6.2 Resource discs Each unit is supplied with the following discs / Flash Drive:- LoggerNet software from Campbell Scientific Ltd CR800/1000 program created by GEOSENSE Ltd Campbell Scientific resource which includes the manuals for CR800, CR100 and AVW200 plus all other products in their range. 6.3 Laptop/PC Computer Setup The Campbell LoggerNet software is shipped on a CD. Therefore a CD drive on a laptop or PC will be required for a straightforward installation. Where a CD drive is not available on the machine on to which it is to be installed, the contents of the CD can be copied to a USB memory device and installed from there. From the CD, the installation may begin automatically. If not, either double click on the Setup.exe file in LoggerNet directory of the CD, using Explorer. 32

29 or from the DOS command prompt, type d:\loggernet\setup.exe to start the installation. The software will then begin to load, showing the following window. Select the button. It may ask for permission to continue the installation and Administrators Rights may be required to complete the installation. The software will begin Preparing for the setup. 33

This can either match the PC s clock or it can be offset from the PC s clock to another specific time zone using the options in the following window. When the setup has bee completed, press the Next button. 40

37 A site specific data logger program will have been provided by Geosense. For the 800 series loggers it will end in.cr8 and for the 1000 series loggers it will end.cr1. The program may be pre-loaded onto the logger or it may need to be up-loaded. The program will also be provided on either a CD or a Geosense Flash Drive. The following window displays the program that is currently loaded onto the logger ( if any ) and allows for a new program to be selected and sent to the logger. If necessary, select the program from the source provided follow the instructions to complete the up-load. If the program has been pre-installed on the logger, it is not necessary to re-install it as the program will be re-activated and will run when power to the logger is activated. The following messages are likely to appear. If no data has been recorded or it has all been downloaded, this can be ignored. Otherwise press NO and download data before re-trying. The logger will compile the file as it is loaded When the upload is complete it will be confirmed. Press OK When done, press the Next button on the Send Data window. 41

38 Various information is generated by a logger during it normal running routine. The following window allows the user to select what data it stores for future downloading. Commonly the Public and the Status information are not required so these are de-selected as can be seen below. The other Table ( in this case Test ) will have been generated within the site specific logger file and should be selected, as below. Tick the Table Collection and select the Append data to file option, as above. Select the final destination and name of the data file. Where data is to be collected automatically by LoggerNet, a schedule is defined in the next two windows. The first window include the option to activate the schedule and is used to define the start of the schedule and the collection interval. The second window in Scheduled Collection is used to define the interval and number of re-tries LoggerNet will initiate to obtain the data in the event that it fails to do so at the first attempt. The following re-try are commonly adopted: Primary Retry is set to 2 minutes with 3 re-tries Secondary Retry is set to 1 day, if enabled 42

43 6.6 Logger Programs A site and hardware specific logger program is written to instruct the data logger how and when to perform certain activities. This will be supplied by GEOSENSE on a CD or USB Flash Drive Retrieving a program from a logger If the logger program is stored on the PC that is connected ( or to be connected ) to the logger or the program is available on the CD or USB Flash Drive, there is no need retrieve the program from the logger. However, if the program is not available or it has already been modified from it original form, the current version must be downloaded from the logger. To do this, open the Connect Screen from the Main option on the LoggerNet main window. Click on the Retrieve button located on the lower right of the window. 47

44 In the Save As window, choose a name and location for the downloaded file. The default location is within the LoggerNet directory. If file of the same name already exists in this directory, give the new file a unique name so that it can be easily identified as a variant of the logger file. In this case the file has been given a -v1 identifier. Confirmation of the download is provided when it has been completed. Close or minimise the Connect window. It is not important weather or not the connection to the logger remains connected or is disconnected, at this stage Changing the Scan Interval It may be necessary to change the time interval between each scan that the logger performs. This will involve changing the parameter embedded in the software that is running within the logger. From the main LoggerNet window, select to open the Program software package called CRBasic Editor 48

45 The Editor will open with either the default program in its window or the last file that was Use the File, Open commands to select and open the file that has just been downloaded To alter the SCAN INTERVAL scroll down the program to locate the Main Program section. Locate the Scan command. A typical layout can be seen in the window below. The units within the brackets (in this case 60,Min,0,0) set the scan interval. Change only the first two parameters. Right click the mouse on the parameter to select alternatives. Type the numeric value. (text beginning with a is a comment, NOT part of the program) 49

46 6.6.3 Entering the Calibration Values Some logger programs require the use of instruments specific calibration and/or initial/zero reading values to automatically convert the raw data into values in engineering units. This will require the user to enter these values into the logger program for instruments installed on site. The default settings for each sensor are Calibration Constant (K) =1 and the Zero or Initial Reading (Z)=0 for each sensor. The characters in the brackets next to the K or Z are the names or numbers of the instruments, in the order that they are connected to the logger. Without the calibration values in the software, only the Raw values from each sensor will be recorded. For the first instrument,enter the Linear calibration Constant from the Calibration sheet for the instrument connected to the loggers first input channel, replacing the 1. For example K(1) = Then enter the Zero or Initial reading corresponding to the same instrument, replacing the 0. For example Z(1) = A Zero Reading ( most commonly associated with Vibrating Wire pressure sensing equipment ) is the value recorded when the instrument has Zero pressure acting on it. An Initial Reading ( for most other instruments is the reading recorded when the sensor is installed and it s readings have stabilised. This is the starting point to which all subsequent readings will be referenced to calculate changes. For details of how to determine the Zero or Initial reading, consult the manual for the instruments being connected to the logger. 50

47 When the required values have been entered into the software, it is necessary to up-load the program to the logger. However, to check that no format errors have occurred, it is necessary to first compile the program. From the menu bar in the Editor, select Compile and Compile. This operation will return a result of the compilation and indicate if, and where, any errors exist. For example in the window above, a typing mistake has resulted in an error in Line 74 where the wrong characters have been included in the calibration value. Select the File, Save As option to save the file with a new name to indicate that it has been updated with the calibration details. For example, this file could be called :- Crackmeter-Cal.CR8 Now follow the file up-loading sequence detailed in section 6.7 in this manual to send the modified program to the logger and re-start the logger. 51

48 6.6.4 Changing the Excitation Frequency for Vibrating Wire Sensors It may be necessary to set or change the frequency range that an AVW200 Vibrating Wire interface uses to excite a particular type, or types, of sensors. Where the program has been configured for a particular site using specified sensors, this should not be necessary. However, the need to change this range could arise for a number of reasons some of which are :- A different type of Vibrating Wire sensor is attached to the logger where its normal operating range varies from that specified when the program was written. External interference at a particular frequency may be affecting the instrument readings. Modifying the excitation range can be carried out from within the logger program. Having either Retrieved the program from the logger or loaded it from another drive, use the main LoggerNet window, to open the Program software package called CRBasic Editor Open the logger program file to be edited. 52

49 Scroll down to locate the sub routine called Sub Read_VW. The typical line of code highlighted in the above window is detailed below... AVW200 (AVW_Result,Com1,200,200,Dest(),1,1,1,1400,2800,2,_50Hz,1,0) The two numbers in RED can be edited to change the Minimum and Maximum range of the excitation frequency used to read the sensors. This Excitation Value is in FREQUENCY (Hertz - H z ) NOT in Linear DIGITS To determine a suitable excitation frequency for a particular instrument, it is necessary to have its current reading in Hz or convert its operating range from Digits to Frequency Frequency = Square Root of (the value in digits x 1000) For example if the Digits reading is 4556, the equivalent frequency would be In this example and excitation range of 2000 to 2500 could be used. This would be a suitable excitation range for a single instrument at its current reading. It must be remembered that if the reading changes significantly or a number of instruments are read using the same reading routine, they may be outside this range. To set a range that would suit a group of instruments, look at their calibration sheets and convert the Lowest and Highest Digit values recorded during their calibration, into Frequency. Round these to the nearest 100 Hz and use these values as the upper and lower limits of the sensor excitation range. Type in the new values, replacing those in the position of the numbers highlighted in red above. 53

50 When the required values have been entered into the software, it is necessary to up-load the program to the logger. However, to check that no format errors have occurred, it is necessary to first compile the program. From the menu bar in the Editor, select Compile and Compile. This operation will return a result of the compilation and indicate if, and where, any errors exist. For example in the window above, a typing mistake has resulted in an error in Line 74 where the wrong characters have been included in the calibration value. Select the File, Save As option to save the file with a new name to indicate that it has been updated with the calibration details. For example, this file could be called :-Crackmeter -Cal.CR8 Now follow the file up-loading sequence detailed in section 6.7 in this manual to send the modified program to the logger and re-start the logger. 54

51 6.7 Sending a program to a Logger Whether or not the program has been modified, the following procedure is adopted to load it onto the logger. From the Connect window, establish a connection to the logger following the procedure detailed in section 6.4 of this manual. Press the Send button of the right side of the window. This will open a file selection window allowing the user to browse to the location of the logger program. The default save and open location is the LoggerNet folder but if the file is on a CD or Flash drive, its location must be selected. Select the program to be uploaded to the logger. And press Open. A warning will be displayed. If any important data is still stored on the logger, it must be downloaded first so press No at this stage and follow the instructions in section 6.5 of this manual before continuing. 55

52 When ready to load the program onto the logger, press YES on the warning window, shown As soon as the program is loaded and the compiling completed, it will run. It may not take a set of readings immediately as it will wait until a suitable starting time that is consistent with the scan interval that has been set in the program. For example, if a scan interval of 1 hour has been selected, the logger will wait until the beginning of the next hour to start its scan. 56
