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].
Each product has different reflective properties. In addition,
there are various interfering factors which have to be taken into
account: agitated product surfaces and foam generation (with
liquids); dust generation, material cones and echoes from the
vessel wall (with solids). To adapt the sensor to these different
conditions, you should first select in this menu item under
"M
edium" the selection "Liquid" or "Solid".
With coax versions, this menu item must be set to "Liquid".

Depending on the dielectric figure (dielectri value or ε
r
),
measured products can have a different reflective property.
Therefore an additional selection possibility is available.
Under "Sensitivity" you can select "Standard (DK ≥ 2)" or
"I
ncreased sensitivity (DK < 2)".
Through this, the sensor is adapted perfectly to the product
and measurement reliability, particularly in products with bad
reflective properties, is considerably increased.
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.
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.
