1. Introduction The CS574A probe monitors the electrical conductivity (EC) and temperature of fresh water. It connects to a Campbell Scientific data logger using the A547 interface. This probe is compatible with most Campbell Scientific data loggers. NOTE: This manual provides information only for CRBasic data loggers. For retired Edlog data logger support, see an older manual at www.campbellsci.com/old-manuals...

4. Click on the Wiring tab to see how the sensor is to be wired to the A547 and data logger. 5. In Output Setup, type the scan rate, meaningful table names, and Data Output Storage Interval. Click Next. CS574A Conductivity and Temperature Probe and A547 Interface...
6. Select the measurement and its associated output option. 7. Click Finish and save the program. Send the program to the data logger if the data logger is connected to the computer. 8. If the sensor is connected to the data logger, check the output of the sensor in the data display in LoggerNet, RTDAQ, or PC400 to make sure it is making reasonable measurements.

Weight: 45 g (2 oz) Temperature rating: –15 to 50 °C 7. Installation If you are programming your data logger with Short Cut, skip Wiring (p. 8) and Programming 9). Short Cut does this work for you. See QuickStart (p. 1) for a Short Cut tutorial. 7.1 Site selection The CS574A measures the EC of water inside the hole running through the sensor, so detection of rapid changes in EC requires the probe be flushed continuously.
FIGURE 7-1. CS574A wiring diagram 7.4 Programming Short Cut is the best source for up-to-date programming code for Campbell Scientific data loggers. If your data acquisition requirements are simple, you can probably create and maintain a data logger program exclusively with Short Cut. If your data acquisition needs are more complex, the files that Short Cut creates are a great source for programming code to start a new program or add to an existing custom program.
7.4.1 EC measurement NOTE: Older data loggers, such as the CR800-series and CR1000, use a different method to measure EC. Refer to the CR1000 example program at www.campbellsci.com/downloads/cs547a- program-examples for more information. BrFull() BrFull() 1. Measure the voltage output using the CRBasic instruction.
resistance measurement, and converts the result to temperature using the Steinhart-Hart equation. See Measurement and output linearization section in the 107 manual for more Therm107() information. instruction and parameters are as follows: Therm107(Dest, Reps, SEChan, VxChan, SettlingTime, Integ/fN1, Mult, Offset) Set Mult to 1 and Offset to 0, which reports temperature as degree Celsius.
8. Operation 8.1 Calibration 8.1.1 Conversion factors 1 S (Siemens) = 1 mho = 1/ohm –1 –1 –1 Although mS·cm and µS·cm are the commonly used units of EC, the SI base unit is S·m . The –1 result of the example programs is mS·cm EC measurements can be used to estimate dissolved solids.
(p. 8). Program the data logger to make the field calibration. A downloadable calibration program is available at www.campbellsci.com/downloads/cs547a-program-examples The calibration solution temperature must be between 1 and 35 °C; a polynomial is used to correct for temperature errors within this range. The solution constant of 1.408 mS/cm (for prepared solution mentioned previously), is valid only for a 0.01 molal KCl solution.

Appendix A. Importing Short Cut code into CRBasic Editor Short Cut creates a .DEF file that contains wiring information and a program file that can be imported into the CRBasic Editor. By default, these files reside in the C:\campbellsci\SCWin folder. Import Short Cut program file and wiring information into CRBasic Editor: 1.
