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 reli-
ability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
settings with [OK] and jump to the next menu item with the [ESC] and
the [->] key.

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, it is the
distance from the sensor to the medium surface that is measured. To
indicate the actual level, the measured distance must be assigned to
a certain height percentage.
To perform the adjustment, enter the distance with full and empty ves-
sel, see the following example:
