7. Select any other sensors you have, and then finish the remaining Short Cut
steps to complete the program. The remaining steps are outlined in Short
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.
