The value is an indication for the reliability and reproducibility of the

switching point.

more reliable the measurement. The automatically calculated damp-

ing is also oriented around the Delta I value. The higher the value, the

lower the damping.

A Delta I value below 10 % is an indication for a critical measurement.

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dierentvalues:

Pulse rate of the sensor

Current output

Switching function of the relay

Information:

The simulation is automatically terminated 10 minutes after the last

pressing of a key.

The sensor calculates a suitable integration time automatically.
