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 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.
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.
