CJC Mode 

 

CJ (Cold Junction) Temperature Mode 
 
Available Options: 
 

AUTO 

CJ Temperature is TC Terminal’s temperature. 

MANUAL 

CJ Temperature is user selectable irrespective of 
TC Terminal temperature.  

RTD 
COMPENSATION 

When using an external Reference Junction, UC-12 
measures or simulates the thermovoltage. 

 

CJC Adjustment 

CJ Temperature adjustment for Manual CJC Temperature. 

External RJ 
Sensor 

The Reference Junction temperature is measured using and 
RTD sensor connected to RTD terminals
