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 dene

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.

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 specications is always the seal surface of

the process tting.
