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.
