Setting the switching delay

NOTICE
The tank can overflow if the switching delay is set for too long.
‣
The switching delay causes the device to signal the point level after a delay. This is
highly useful in tanks with turbulent medium surfaces caused, for example, by the
filling process or by collapsing mounds. By doing so, you ensure that the filling of the
tank does not end until the probe is continuously covered by the medium.
A switching delay that is too short may, for example, cause the filling process to be
restarted as soon as the medium surface settles.
