Campbell CR300 Series Operator's Manual page 21

For most sensors and measurements,
a dialog window is then presented
with several fields and options.
Click Help to learn more about any
field or option.
Click OK in the dialog window to accept default options that include selection of 1 sensor named Temp_C, and
PTemp_C as the reference temperature measurement.
NOTE PTemp_C is the temperature measurement of the processing board and therefore does
not provide an accurate reference temperature for the thermocouple. To make an
accurate thermocouple measurement with the CR300, an external reference temperature
must be used.
NOTE BattV (battery voltage) and PTemp_C (processing board temperature) are default
measurements. During operation, battery and temperature should be recorded at least
daily to assist in monitoring system status.
After adding the measurement, click
Wiring Diagram to see how the
sensor is to be wired to the
datalogger. Under Progress, click
Sensors to return to the sensor
selection screen.
