Cold Junction Compensation (CJC) 

The 7085A has a temperature display on the module. EasyCal software automatically reads 
the CJC from the 7085A in the testing application.  

 

  
When using a 

7051 module

 the 7085A can be manually configured for operation.  

A simple user interface displays the CJC reading from the 7085A module.
