When non-contact level sensors are used, the measurement can be
influenced by the respective process conditions. In this menu item,
the measurement reliability of the level echo is displayed as dB value.
The measurement reliability equals signal strength minus noise. The
higher the value, the more reliable the measurement. With a function-

The "Echo curve" shows the signal strength of the echoes over the
measuring range in dB. The signal strength enables an evaluation of
the quality of the measurement.
