The PROBE adjustment is performed in two steps:
55
a) Application of mV signal:
(*) RTD2, for PROBE adjustment, refers to the drawing shown above.
b) Application of standard resistors:
Connect a decade box or standard resistor to the probe connector, at positions RTD1, RTD2, RTD3 and
RTD4, as shown above.
CJC adjustment
The adjustment of the cold junction related to the thermocouple output is similar to the one related to the
thermocouple input. But the temperature should take at the GND OUT terminal.
