2. Confirm again with [OK].

3. Confirm again with [OK].

4. Confirm again with [OK] and enter the actual distance from the

sensor to the product surface.

5. All interfering signals in this section are detected by the sensor

and stored after confirming with [OK].

Note:

Check the distance to the product surface, because if an incorrect

(too large) value is entered, the existing level will be saved as false

signal. The filling level would then no longer be detectable in this area.
If a false signal suppression has already been created in the sensor,

the following menu window appears when selecting "False signal

suppression":

The menu item "Delete" is used to completely delete an already cre-

ated false signal suppression. This is useful if the saved false signal

suppression no longer matches the metrological conditions in the

vessel.
The menu item "Extend" is used to extend an already created false

signal suppression. This is useful if a false signal suppression was

carried out with a too high level and not all false signals could be de-

tected. When selecting "Extend", the distance to the product surface

of the created false signal suppression is displayed. This value can

now be changed and the false signal suppression can be extended to

this range.

A linearization is necessary for all vessels in which the vessel volume

does not increase linearly with the level - e.g. in a horizontal cylindri-

cal or spherical tank - and the indication or output of the volume is

required. Corresponding linearization curves are preprogrammed

for these vessels. They represent the correlation between the level

percentage and vessel volume.
