：Calibration of the voltage
：Calibration of the resistance temperature detector
：Calibration of reference junction compensation
[Note]
This recorder is precisely proofread. First of all, please reconfirm a setting value when the instruction value is
abnormal.
The calibration value abnormality doesn't usually occur.
Example) When calibrating the voltage at Channel 1.
