Figure 6-4: Cold junction calibration
* Note: Zero calibration and span calibration must be completed
before CJC calibration. To calibrate CJC, the thermocouple
attached to ADAM-5018 and a standard thermometer
should be used to measure a standard known temperature,
such as the freezing point of pure water. The amount of
offset between the ADAM-5018 and the standard
thermometer is then used in the ADAM utility to complete
CJC calibration.
