too high a level and not all false signals could be detected. When
selecting "Extend", the distance to the product surface of the created
false signal suppression is displayed. This value can now be changed
and the false signal suppression can be extended to this range.
A linearization is necessary for all vessels in which the vessel volume
does not increase linearly with the level - e.g. a horizontal cylindri-
cal 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 [ESC] and [->] key.
Caution:
Note the following if instruments with appropriate approval are used
as part of an overfill protection system according to WHG:
If a linearisation curve is selected, the measuring signal is no longer
necessarily linear to the filling height. This must be considered by the
user especially when setting the switching point on the limit signal
transmitter.
Entering a 4-digit PIN protects the sensor data against unauthorized
access and unintentional modification. In this menu item, the PIN is
displayed or edited and changed. However, this menu item is only
available if adjustment is enabled in the menu "Setup".
In delivery status, the PIN is "0000".
In this menu item, the internal clock of the sensor is set.
