Measured products have different reflective properties depending on
their respective permittivity (dielectric constant). That's why there is an
additional selection option.
Under "Sensitivity" you can select "Standard (DK ≥ 2)" or "Increased
sensitivity (DK < 2)".
Through this the sensor is optimally adapted to the product and
measurement reliability, particularly in products with poor reflective
properties, is considerably increased.
Enter the requested parameters 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. 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. in a horizontal 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".
