Enter the requested parameter via the appropriate keys, save
your settings and jump to the next menu item with the [->] key.
Apart from the medium, the vessel shape can also influence
the measurement. To adapt the sensor to these measuring
conditions, this menu item offers different options depending
on whether liquid or solid is selected. With "Liquid" these are
"Storage tank", "Stilling tube", "Open vessel" or "Stirred
vessel", with "Solid", "Silo" or "Bunker".

Enter the requested parameter via the appropriate keys, save
your settings and jump to the next menu item with the [->] key.
To suppress fluctuations in the measured value display, e.g.
by fluctuating product surfaces, an integration time can be set.
This time can be between 0 and 999 seconds. Keep in mind
that also the reaction time of the complete measurement will
be bigger and the sensor will react on measured value
changes with a delay. In general a time of a few seconds will
be sufficient to smooth the measured value display.

Enter the requested parameter via the appropriate keys, save

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".
