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 109SS is a rugged probe that accurately measures soil or water
temperature in a variety of applications. The sensor consists of a thermistor
encased in a stainless-steel sheath. This design protects the thermistor,
allowing the 109SS to be buried or submerged in harsh, corrosive
environments. It can be submerged in water to 45 m (150 ft) or 63 psi. See
Specifications for a complete list of compatible dataloggers.
