Model 109 Temperature Probe Cut Help, which is accessed by clicking on Help | Contents | Programming Steps. 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. 5. Overview The 109 is a rugged probe that accurately measures air, soil, or water temperature in a variety of applications. The sensor consists of a thermistor encapsulated in an epoxy-filled aluminum housing. This design allows the probe to be buried or submerged in water to 15 m (50 ft) or 21 psi. When measuring air temperature, a 41303-5A radiation shield is normally used to mount the 109 and limit solar radiation loading. See Specifications for a complete list of compatible dataloggers. 6.
