 Sensor calibration of the external Pt100 sensor is carried out in the menu
>ATCalibration<, with the > Status< set to >no< (see page 59).
 Suggested adjustments for external temperature control:
AreaUp/ AreaDown and IntMax / IntMin
see chapter >Limits< on page 56.
 External temperature control does not allow for setpoint setting via the
socket „ext. Pt100“ (see page 32).

8981020 M+R in-line Pt100 sensor
The M+R in-line Pt100 sensor is a flow sensor and can be installed loop
circuit
Notice:
Place the external sensor into the bath medium and securely fix the sensor.
Selftuning:
When performing an selftuning for the controlled system (temperature
application system), the control parameters Xp, Tn and Tv are automatically
determined and stored.
Possible parameters:
off - no
selftuning.
The control parameters ascertained during the last identification are used
for control purposes.
once – single
selftuning (factory setting)
The instrument performs a single selftuning of the controlled system after
each start with the start/stop key
or after receiving a start command
via the interface.
always – continual
selftuning
The instrument performs a selftuning of the controlled system whenever a
new setpoint is to be reached.
Use this setting only when the temperature application system changes
permanently.
