This parameter is described in the operating instructions manual
"Display and adjustment module".
With this parameter you can change the indication of the display.

Diagnostics
Inthismenuitem,youcanenquirethestatusofyoursensor.Innormal
operation, the sensor displays the message "OK". In case of fault, you
willndthecorrespondingfaultcodehere.
This parameter is described in the operating instructions manual
"Display and adjustment module".
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dierenceofthemin.andmax.adjustment
points (Delta I). The value is an indication for the reliability and repro-
ducibility of the measurement.

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.
