requested position with [->]. Set the requested percentage value
with [+] and save with [OK]. The cursor jumps now to the distance

2 E nter 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 S ave the settings with [OK] and move to "Medium selection" with
[->] .
E ach product has different reflective properties. In solids, these are
dust generation, material cones and additional echoes caused by the
vessel wall. Due to the medium selection, the sensor is adapted in an
optimum way to the product and the accuracy, particularly for products
with bad reflective properties, is increased considerably.
