 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:
