Procedures (CH1): Cold Junction (TC method) and CJ 8.12
(measure)
Note: Do the TC mV (measure) calibration before the cold
junction calibration. The conditions for CJ calibration are as
follows:
• Battery mode (with DC charger disconnected)
• CH1 active
• CH2 set to “None”
• Burnout Detection off
• Use miniature TC connectors
There are two methods of doing a cold junction test; the CJ
(TC Method) is the preferred method. Both procedures are
described as follows:
