Input 1 r Function INP1 r 7: process value X1
InP.1 r 1.Fnc 7 X1-Input
In input 1, the sensor type is set for one of the high-impedance voltage inputs:
Input 1 r Sensor type r 42: special (-25...1150 mV) or
41: special (-2,5...115 mV)
InP.1 r S.tyP 41 115 mV
InP.1 r S.tyP 42 1150 mV
Input 1 r meas. value correction r 0: no correction
InP.1 r S.Lin 0no
Temperature measurement (required with non-heated lambda probe)
Any temperature measurement with one of analog inputs INP2 or INP3 can be
used. Select input X2 during function selection (second set-point).

measurement, evaluation in ppm or % must be specified for all
parameters related to the process value.
This is done centrally during configuration.

Whether the temperature of the non-heated l probe is specified in °C or °F can
be selected during configuration.
