Display
With this parameter you can change the display language.
This parameter is described in the operating instructions manual
"Display and adjustment module".
With this parameter you can change the indication of the display.
You can choose if the display should show the actual pulse rate, the
electronics temperature or the percentage value.
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 find 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 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.
Note:
To carry out a simulation with the display and adjustment module,
you have to switch on the simulation switch on the electronics module
(switch position 1).
