Thermocouple Simulation
MC5P is able to mimic a thermocouple at given temperatures. This property is called
thermocouple simulation. It enables checking and calibration of temperature indicators,
recorders, transmitters and other equipment related to temperature measurement with a
thermocouple probe.
In thermocouple simulation the original thermocouple is disconnected from the instru-
ment under test and replaced with MC5P. To the instrument under test MC5P appears as
a thermocouple at the given temperature.
Thermocouple simulation terminals are located in the
ET
module.
