6. CJC Calibration (only for T/C input module)

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.
