False signal suppression
Change now?
Proceed as follows:
1 Move from the measured value display to the main menu
by pushing [OK].
2 Select the menu item "Service" with [–>] and confirm with
[OK]. Now the menu item "False signal suppression" is
displayed.
3 Confirm "False signal suppression - Change now" with
[OK] and select in the below menu "Create new". Enter the
actual distance from the sensor to the product surface. All
false signals in this area are detected by the sensor and
saved 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.
Additional adjustment and diagnosis options such as e.g.
scaling, simulation or trend curve presentation are shown in
the following menu schematic. You will find a detailed
description of these menu items in the operating instructions
manual of the indicating and adjustment module.
