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.
Required settings Options/description
Quantity T/C-Temp
Funct/Port ET: TCi(sim) (for the internal Reference Junction), or
ET: TCx(sim) (for other RJ compensation methods)
Sensor Type Available thermocouple types
Reference Junction Depends on the Function/Port setting.
See subsequent chapters.
Internal Reference Junction
To use the Internal Reference Junction,
select Function/Port ET: TCi(sim). The Ref-
erence Junction compensation method In-
ternal is automatically selected.
External Reference Junction
To use an External Reference Junction,
select Function/Port ET: TCx(sim) and
choose one of the available Reference
Junction compensation methods: Entered,
0°C or available RTD sensors.

Internal Reference Junction on page 93.
