7.1 Sensor
Open the case cover, push one of the two black fastening clips backwards and
pull the display module upwards.
Designation of terminal connectors
7.1.1 Resistance thermometer (RTD) and resistance sensor
The connection of a resistance thermometer (e.g. per EN 60751) into a 2-, 3- or 4-wire
sensor connection or the connection of two identical resistance thermometers into a 2-wire
connection with an identical measuring range. The sensor input of the transmitter has to
be configured in accordance with the actually used sensor connection type, otherwise a
complete use of the possibilities of connection compensation is not possible; furthermore
this may cause additional measuring errors (see chapter 6.2 "Configuration").
7.1.2 Thermocouples (TC)
It is possible to connect one or two identical thermocouples. Make sure that the
thermocouple is connected with the correct polarity. If the lead between the thermocouple
and the transmitter needs to be extended, only use thermal or compensation cable
appropriate for the connected thermocouple type.

Identical dual sensors are supported for all sensor
models, i. e. dual sensor combinations as for example
Pt100/Pt100 or thermocouple type K/ type K are possible.
A further rule is:
Both sensor values have the same unit and the same
sensor range.
