6. Only for ADAM-5018: Execute the CJC (cold junction sensor)
Calibration command. This can be done with the ADAM utility
software. (See the "CJC Calibration" option in the Calibration
submenu of the ADAM utility software.)
* Note: Zero calibration and span calibration must be com-
pleted before CJC calibration. To calibrate CJC, the
thermocouple attached to ADAM-5018 and a stan-
dard 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.
