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.

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
".
