To suppress fluctuations in the measured value display, e. g. caused
by an agitated medium surface, a damping can be set. This time can
be between 0 and 999 seconds. Keep in mind that the reaction time of
the entire measurement will then be longer and the sensor will react
to measured value changes with a delay. In general, a period of a few
seconds is sufficient to smooth the measured value display.

Enter the requested parameters via the appropriate keys, save your
settings and jump to the next menu item with the [->] key.
A linearisation is necessary for all vessels in which the vessel volume
does not increase linearly with the level - e.g. in a horizontal cylindri-
cal or spherical tank - and the indication or output of the volume is
required. Corresponding linearisation curves are preprogrammed for
these vessels. They represent the correlation between the level per-
centage 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.
In this menu item you can enter an unambiguous designation for the
sensor, e.g. the measurement loop name or the tank or product des-
ignation. 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.
In the menu item " Display" you can define how the measured value
should be presented on the display.
The following indication values are available:
•
Height
•
Distance
•
