5 Set up with the display and adjustment module
arisation 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 appro-
priate keys, save your settings and jump to the
next menu item with the [->] key.
Sensor-TAG
In this menu item, a clear identification can be
assigned to the sensor, e.g. the measurement
loop name or the tank or product name.

With this menu item, the Basic adjustment is fi-
nished and you can now jump to the main menu
with the [ESC] key.
False signal suppression
High nozzles or vessel installations, such as
e.g. struts or agitators as well as buildup and
weld joints on the vessel walls cause interfering
reflections which can impair the measurement.
A false echo storage detects and marks these
false echoes, so that they are no longer taken
into account for the level measurement. A false
echo memory should be created with empty
vessel so that all potential interfering reflections
will be detected.

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 me-
nu "Create new". Enter the actual distance
from the sensor to the medium surface. All
false signals in this area are detected by
the sensor and saved after confirming with
[OK].
Note:
Check the distance to the medium sur-
face, 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.
Copy sensor data
This function enables reading out parameter
adjustment data as well as writing parameter
adjustment data into the sensor via the display
and adjustment module. A description of the
function is available in the operating instructions
manual "Display and adjustment module".
