Connection when
easuring/simulating
thermocouples
using Internal
Reference Junction
Mode:
External Reference Junction
When using an external Reference Junction, UC-12 measures or
simulates the thermo-
voltage using the “T/C” terminals. The
following external Reference Junction compensation methods are
available, To select this compensation method, set the SCR1 field
“T/C Sensor Measurement” or “T/C Sensor Simulation”, make sure
the Unit is a temperature unit and set the CJC Mo
de to “RTD
Compensation”.
External RTD:
To be used when The Reference Junction temperature is
measured using an
RTD sensor connected
to UC-
12’s RTD
terminals.

compensation
method “External
RTD”:
Note: If you connect an
RTD sensor to the
RTD connectors, there
is no galvanic isolation
between the
thermocouple and the RTD sensor.
