Model 109SS Temperature Probe 1. Introduction The 109SS Temperature Probe uses a thermistor to measure temperature in soil and water. It is compatible with all CRBasic dataloggers except the CR9000(X). See Section 6, Specifications, for a list of compatible CRBasic dataloggers. For Edlog datalogger support, check the availability of an older manual at www.campbellsci.com/old-manuals, or contact a Campbell Scientific application engineer for assistance. 2. 3. 4.
Model 109SS Temperature Probe 2 2. The Short Cut installation should place an icon on the desktop of your computer. To open Short Cut, click on this icon. 3. When Short Cut opens, select New Program. 4. Select Datalogger Model and Scan Interval (default of 5 or 10 seconds is OK for most applications). Click Next.
Model 109SS Temperature Probe 5. Under the Available Sensors and Devices list, select the Sensors folder, then select the Temperature sub-folder. Select 109 Temperature Probe. Click to move the selection to the Selected device window. Data defaults to degree Celsius. This can be changed by clicking the Deg C box and selecting Deg F, for degrees Fahrenheit, or K, for Kelvin. 6.
Model 109SS Temperature Probe 5. 8. If LoggerNet, PC400, RTDAQ, or PC200W is running on your PC, and the PC to datalogger connection is active, you can click Finish in Short Cut and you will be prompted to send the program just created to the datalogger. 9. If the sensor is connected to the datalogger, as shown in the wiring diagram in step 6, check the output of the sensor in the datalogger support software data display to make sure it is making reasonable measurements.

Steinhart-Hart linearization error 7. Installation If you are programming your datalogger with Short Cut, skip Section 7.1, Wiring to Datalogger, and Section 7.2, Datalogger Programming. Short Cut does this work for you. See Section 4, Quickstart, for a Short Cut tutorial. 7.
Model 109SS Temperature Probe 7.2 Datalogger Programming Short Cut is the best source for up-to-date datalogger programming code. Programming code is needed when: • • Creating a program for a new datalogger installation Adding sensors to an existing datalogger program If your data acquisition requirements are simple, you can probably create and maintain a datalogger program exclusively with Short Cut.
Model 109SS Temperature Probe 7.3 Water Temperature Installation 109SS probes can be submerged to 45 m (150 ft) or 63 psi. The 109SS is not weighted, so a weighting system should be added, or the probe secured to a submerged object such as a piling. 7.4 Soil Temperature Installation The 109SS tends to measure the average temperature over its length, so burying the probe such that the measurement tip is horizontal to the soil surface at the desired depth is usually preferred.
Model 109SS Temperature Probe The ratio of measured voltage (Vs) to excitation voltage (Vx) is related to thermistor resistance (Rs) and the 24.
Model 109SS Temperature Probe For CR6 datalogger: Therm109(T109_C,1,U1,U10,20000,_60Hz,1.0,0.0) For CR800, CR1000, CR3000, and CR5000 dataloggers: Therm109(T109_C,1,1,1,20000,_60Hz,1.0,0.0) A setting time parameter is not available for CR200(X) series dataloggers. 9. Troubleshooting and Maintenance NOTE 9.1 All factory repairs and recalibrations require a returned material authorization (RMA) and completion of the “Declaration of Hazardous Material and Decontamination” form.

Appendix A. Importing Short Cut Code Into CRBasic Editor This tutorial shows: • • How to import a Short Cut program into a program editor for additional refinement How to import a wiring diagram from Short Cut into the comments of a custom program Short Cut creates the following files, which can be imported into CRBasic Editor. Assuming defaults were used when Short Cut was installed, these files reside in the C:\campbellsci\SCWin folder: • • • • • • • .DEF (wiring and memory usage information) .
