Enter the requested parameters via the appropriate keys, save your
settings with [OK] and jump to the next menu item with the [ESC] and
the [->] key.
Vessel height/Measuring range
Through this selection the operating range of the sensor is adapted
to the vessel height, which considerably increases measurement
certaintyunderdierentbasicconditions.
The min. adjustment must be carried out independently of this.
Enter the requested parameters via the appropriate keys, save your

example through condensation, the radar sensor can detect under
certain circumstances only the medium with the higher dielectric
constant. Keep in mind that layer interfaces can cause faulty meas-
urements.
If you want to measure the total height of both liquids reliably, please
contact our service department or use an instrument specially de-
signed for interface measurement.
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:
