1. In this menu item you can select the application.
2. In the menu item "Medium - Dielectric constant" you can define
the type of medium (medium).

"Max. adjustment".
4. A "Linearization" is recommended for all vessels in which the
vessel volume does not increase linearly with the level - e.g. in a
horizontal cylindrical or spherical tank. Activate the appropriate
curve.
The sensor measures the distance from the sensor (reference plane)

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
point for these distance specifications is always the seal surface of
the thread or flange.
