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

Information:

The simulation is terminated automatically 60 minutes after the last

key has been pressed.
