3. Set the requested percentage value with [+] and save with [OK].

The cursor jumps now to the distance value.

percentage value) for the full vessel. Keep in mind that the max.

level must lie below the min. distance to the antenna edge.

5. Save settings with [OK]

The respective min. and max. measured value is saved in the sensor.

The values are displayed in the menu item "Peak values".

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-

ing measurement, the values are > 10 dB.

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.

The "False signal suppression" displays the saved false echoes (see

menu "Additional settings") of the empty vessel with signal strength in

"dB" over the measuring range.
