Analog I/O Modules Calibration
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.
