1 Prepare the % value for editing with [OK] and set the
cursor to the requested position with [->]. Set the
requested percentage value with [+] and save with [OK].
The cursor jumps now to the distance value.
2 Enter the appropriate distance value in m (corresponding
to the percentage value) for the full vessel. Keep in mind
that the max. level must lie below the dead band.
3 Save the settings with [OK].
To suppress fluctuations in the measured value display, e.g.
caused by an agitated product surface, an integration time 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 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. 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".
