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.
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
point for these distance specifications is always the seal surface of
the thread or flange.
1. In the menu "Additional settings", menu item "Damping" you can
adjust the requested damping of the output signal.
2. Select the parameter of the current output and the output charac-
teristics in the menu item "Current output".
