3. Prepare the % value for editing with [OK]
and set the cursor to the requested position
with [->]. Set the requested percentage va-
lue with [+] and save with [OK]. The cursor
jumps now to the distance value.
4. Enter the suitable distance value in m for
empty vessel (e.g. distance from the sensor
to the vessel bottom) corresponding to the
percentage value.
5. Save the settings with [OK] and move to
"Max. adjustment" with [->].
Carry out max. adjustment
Proceed as follows:

1. Prepare the % value for editing with [OK]
and set the cursor to the requested position
with [->]. Set the requested percentage va-
lue 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 blocking distance.
3. Save the settings with [OK] and move to
"Medium selection" with [->].
Medium selection
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 "Liquid" or "Solid".
Medium
Liquid
With solids, you can also choose between
"Powder/Dust", "Granular/Pellets" or "Ballast/
Pebbels".
Through this additional selection, the sensor is

adapted perfectly to the product and measure-
ment reliability, particularly in products with poor
reflective properties, is considerably increased.
Enter the requested parameters via the appro-
priate keys, save your settings and jump to the
next menu item with the [->] key.
Vessel shape
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 bulk solid is selected. With "Li-
quids" these are "Storage tank", "Stilling tube",
"Open vessel" or "Stirred vessel", with "Solid",
"Silo" or "Bunker".

priate keys, save your settings and jump to the
next menu item with the [->] key.
Damping
To suppress fluctuations in the measured value
display, e. g. caused by an agitated medium
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 mea-
surement 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 suffici-
ent to smooth the measured value display.

priate keys, save your settings and jump to the

Linearisation curve
A linearisation is necessary for all vessels in
which the vessel volume does not increase line-
arly with the level - e.g. in a horizontal cylindrical
or spherical tank - and the indication or output
of the volume is required. Corresponding line-
