Note:
A false signal suppression detects, marks and saves these false sig-
nals so that they are no longer taken into account for level measure-
ment.
This should be done with the low level so that all potential interfering
reflections can be detected.
Proceed as follows:
1. Select the menu item "Additional settins" with [->] and confirm
with [OK]. With [->] you have to select the menu item "False
signal suppression" and confirm with [OK].
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":
