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.
A linearization is necessary for all vessels in which the vessel volume
does not increase linearly with the level - e.g. in a horizontal cylindrical
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. By activating the appropriate curve,
the volume percentage of the vessel is displayed correctly. If the
volume should not be displayed in percent but e.g. in l or kg, a scaling
can be also set in the menu item "Display".

Enter the requested parameters via the appropriate keys, save your
settings and jump to the next menu item with the [->] key.
This function enables reading out parameter adjustment data as well
as writing parameter adjustment data into the sensor via the indicating
and adjustment module. A description of the function is available in the
operating instructions manual "Indicating and adjustment module".
The following data are read out or written with this function:
l Measured value presentation
l Adjustment
l Medium
l Vessel form
l Damping
l Linearisation curve
l Sensor-TAG
l Displayed value
l Unit of measurement
l Language
l Sensitivity
l Dielectric figure
The following safety-relevant data are not read out or written:
l HART mode
