To suppress fluctuations in the measured value display, e. g. caused
by an agitated product 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 linearization is necessary for all vessels in which the vessel volume
does not increase linearly with the level - e. g. with a cylindrical 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".

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 low level so that all potential interfering reflections will
be detected.
