Also the vessel form can influence the measurement apart from the
medium and the application. To adapt the sensor to these measure-
ment conditions, this menu item offers you different options for vessel
bottom and ceiling in case of certain applications.
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.
As the radar sensor is a distance measuring instrument, the distance
from the sensor to the product surface is measured. For indication of
the real level, an allocation of the measured distance to the percenta-
ge height must be carried out.
To perform the adjustment, enter the distance with full and empty
vessel, see the following example:

1 Min. level = max. meas. distance
2 Max. level = min. meas. distance
If these values are not known, an adjustment with the distances of for
example 10 % and 90 % is possible. Starting point for these distance
specifications is always the seal surface of the thread or flange. By
means of these settings, the real level will be calculated.
The real product level during this adjustment is not important,
because the min./max. adjustment is always carried out without chan-
