6.2.2 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:

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.
