6.4 Hysteresis
If the level is fluctuating around the set value (e.g., wave movement during filling), the hysteresis
keeps the switching state of the outputs stable. When the level is increasing, the output switches
when the respective switching point (SP) is reached; if the level sinks again, the output switches back
only after the reset point (RP) has been reached.

6.5 Application notes

The error signal of the sensor is analogous to the cable breakage control.

Description
This function makes it possible to save diagnosic data in the device.
This parameter describes the quality of the measurement signal by using two
values; signal strength and signal interference.
Signal strength:
> 100 very good signal quality
< 20 poor signal quality
Signal interference:
> 80 strong signal interference
