Note:
This should be done with the lowest possible level so that all potential
interfering reflections can be detected.
Proceed as follows:
1. Select menu item "
Additional settings
" with
[->]
and confirm with
[OK]
. With
[->]
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 range are detected by the sensor and
stored after being confirmed 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 a false
signal. The 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 existing 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-
