The sensor measures the distance from the sensor to the product
surface. For indication of the real level, an allocation of the measured
distance to the percentage height must be carried out.
The actual level is then calculated on the basis of these entered
values. At the same time, the operating range of the sensor is limited
from maximum range to the requested range.

The actual product level during this adjustment is not important,
because the min./max. adjustment is always carried out without
changing the product level. These settings can be made ahead of
time without the instrument having to be installed.
