1. In this menu item you can select the application. You can choose
between level and interface measurement.
2. In the menu item "Medium - Dielectric constant" you can define
the medium type (medium).
3. Carry out the adjustment in the menu items "Min. adjustment" and
"Max. adjustment".
4. A "Linearization" is required for all vessels in which the vessel vol-
ume does not increase linearly with the level - e.g. in a horizontal
cylindrical or spherical tank. Activate the appropriate curve.
5. A "False signal suppression" detects, marks and saves the false
signals so that they are no longer taken into account for level
measurement. We generally recommend a false signal suppres-
sion.
The sensor measures the distance from the sensor (reference plane)
to the product surface.

1 Reference plane
2 Probe length L
3 Measuring range (default setting refers to the measuring range in water)
4 Upper dead band (in this area no measurement is possible)
5 Lower dead band (in this area no measurement is possible)
For this adjustment, the distance is entered when the vessel is full
and nearly empty. If these values are not known, an adjustment with
other distances, for example, 10 % and 90 % is also possible. Starting
