Cold Junction compensation: N-type thermocouple and a
reference junction, for example an
ice bath.
Note that Cold Junction compensation is only possible when
”Measure/Adjust/Calibrate” is selected.
The number and type of electrical inputs to be checked is user-
definable. You can also define if you want to check the inputs by just
measuring them or to measure, adjust and then calibrate the electrical
inputs.
Cold Junction compensation requires a special setup, using a
calibrated temperature source, for example an ice bath. This and the
measurement principles are shown briefly below:
