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
":
Delete: An already created false signal suppression will be com-
pletely deleted. This is useful if the saved false signal suppression no
longer matches the metrological conditions in the vessel.
Extend: is used to extend an already created false signal suppres-
sion. This is useful if a false signal suppression was carried out with
a too high level and not all false signals could be detected. 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.
