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

The peak value function holds the max. and min. values during opera-
tion.
This parameter is described in the operating instructions manual

Here, you can retrieve the adjustment value of the sensor. This is the
percentagevalueofthemax.pulserateatwhichthesensorswitches
over.
If you have carried out a single point adjustment, this is the entered
value.Withatwo-pointadjustment,thisisthecalculatedvalue.
The value is an indication for the reliability and reproducibility of the
switchingpoint.
