Enter the requested parameter via the appropriate keys, save
your settings and jump to the next menu item with the [–>] key.
A linearization is necessary for all vessels in which the vessel
volume does not increase linearly with the level – e.g. in a
cylindrical or spherical tank -–and the indication or output of
the volume is requested. 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 parameter via the appropriate keys, save
your settings and jump to the next menu item with the [–>] key.
In this menu item you can enter an unambiguous designation
for the sensor, e.g. the measurement loop name or the tank or
product designation. In digital systems and in the documen-
tation of larger plants, a singular designation should be entered
for exact identification of individual measuring sites.

With this menu item, the Basic adjustment is finished and you
can now jump to the main menu with the [ESC] key.
High sockets 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 measure-
ment. A false signal suppression detects, marks and saves
these false signals, so that they are no longer taken into
account for the level measurement. This false signal sup-
pression should be created with empty vessel so that all
potential interfering reflections will be detected.
