Connectable thermocouples and their measuring ranges
The linearization of the thermocouple characteristic curves occurs for thermocouples in
accordance with IEC 584.
For thermal resistance measurements, linearization of the characteristic curves is based on
DIN 43760 and IEC 751.

In the case of internal compensation in the module, all 8 channels are available for temperature
measurements thus with different types of thermocouples.
● If the input is short-circuited, the terminal temperature of the module is supplied.
This does not apply to thermocouple type B, which is not suitable for measurements in the ambient
temperature range.

This type of measurement supports the following compensations:
● Use of a compensation box
The compensation box must be compatible with the type of thermocouple connected. Connection to
channel 7.
● Use of thermal resistors in climatic range (e.g. Pt100) for compensation.
The absolute terminal temperature is determined in the climatic range with a thermal resistor (e.g.
Pt 100) for the compensation. In this case, the thermocouples to be compensated can be of different
types.
Connection to channels 6 and 7. This channel group must be configured in the measurement type
as "Thermal resistance" and in the measuring range as "Pt 100 climatic range"
