all other signal types require additional settings.
For the transfer of analogue signal values to actual values, only the transfer ramp is now
defined. For this purpose, the minimum and maximum support point of the characteristic
curve is specified and the respective actual values are amended (MIN signal/value assignment
and MAX signal/value assignment).
The value for the minimum signal describes the lower signal value of the transmission ramp
with an associated value of 0 %. This is the equivalent of 0.0 mA for -10 °C in this example.

NOTICE
If another usage type has been set to "Not configured" in the "Select type
of use" menu, check whether the analogue input is already used for an-
other type of use.
If necessary, select a different source.
NOTICE
If the analogue input is configured to the signal type PT1000 for a temper-
ature sensor, a "temperature correction value" can be set to compensate
for the electrical resistance if the sensor cable is longer than 3 m.
NOTICE
If the signal type PT1000 has been selected, it's possible to set a temper-
ature correction value for the measured temperature. With this the elec-
trical resistance of a long sensor cable can be compensated.
