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, PCE-
MCA 50 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
