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.

Caution:
Note the following, if VEGAFLEX 66 is used as part of an overfill
protection system according to WHG:

If a linearisation curve is selected, the measuring signal is no longer
compulsorily linear proportional to the level. This must be taken into
consideration by the user, particularly when adjusting the switching
point on the level switch.

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 documentation of larger
plants, a singular designation should be entered for exact identification
of individual measuring points.

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 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.

Probes in coax version require no gating out of false echoes since they
are not influenced by false reflections.
