6.3.2 Thermocouple measurements
The electrical module measures signals from the thermocouple and shows it in different
engineering units (°C, °F, K).
Thermocouple types, measuring range, linearity error and related resolutions are given in the
following table:
Type Range/°C Resolution/°C

Table 2 – Thermocouple measurements table
It is possible to perform the measurement in two different ways: with internal reference (cold
junction), with external reference cold junction by entering the reference value through the
keyboard. When internal reference cold junction is selected, the ambient temperature is measured
through the thermocouple pins using a special thermo resistance. This temperature value is used
for compensation. The Standard connector Mignon for thermocouple is shown in Figure 1. The
thermoresistance for compensation of the reference cold junction is integrated in the same
connector.
