Through this selection the operating range of the sensor is adapted
to the vessel height, which considerably increases measurement
certainty under different basic conditions.
The min. adjustment must be carried out independently of this.
Enter the requested parameters via the appropriate keys, save your

Since the radar sensor is a distance measuring instrument, the
distance from the sensor to the product surface is measured. To
indicate the actual level, an allocation of the measured distance to the
percentage height must be carried out.
To perform the adjustment, enter the distance with full and empty ves-
sel, see the following example:

Fig. 40: Parameter adjustment example min./max. adjustment
1 Min. level = max. measuring distance
2 Max. level = min. measuring distance
If these values are not known, an adjustment with the distances of e.g.
10 % and 90 % is possible. Starting point for these distance specifica
