5. Save the settings with [OK] and move to "Max. adjustment" with
[->].
Proceed as follows:
Max. adjustment
100.00 %
=
1.000 m(d)
2.000 m(d)
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] and move to "Medium selection" with
[->].
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 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.
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 " Liquids" these are " Storage tank", "
Stilling tube", " Open vessel" or " Stirred vessel", with " Solid", " Silo"
or " Bunker".

Enter the requested parameters via the appropriate keys, save your
