The peak value function holds the max. and min. values during opera-
tion.
This parameter is described in the operating instructions manual
"Display and adjustment module".
Here you can retrieve the adjustment value of the sensor. This is the
percentage value of the difference of the min. and max. adjustment
points (Delta I). The value is an indication for the reliability and repro-
ducibility of the measurement.
The higher the difference between the two adjustment points,
the higher the differential value (Delta I) and the more reliable the
measurement. A Delta I value below 10 % is an indication for a critical
measurement.
To increase the Delta I value, you have to increase the distance of the
min. and max. adjustment points in the linearization.
In this menu item you can simulate measured values via the current
output. This allows the signal path to be tested, e.g. through down-
stream indicating instruments or the input card of the control system.
You can simulate different values:
Pulse rate of the sensor
Process value
Current output
Switching function of the relay
