bypass/pipe
The "bypass/pipe" option is designed especially for the installation of probes in a
bypass or a stilling well. If this option is selected, the upper blocking distance is preset to
100 mm.
coax probe
Select the "coax probe" option when using a coax probe. When this setting is made,
the evaluation is adapted to the high sensitivity of the coax probe. This option should,
therefore, not be selected when using rope or rod probes.
concrete wall
The "concrete wall" option takes into account the signal-damping property of concrete
walls when mounting with < 1 m distance to the wall.

Function "medium property" (003)

The lower group applies to very loose or loosened bulk solids. Reduction of the max.
possible measuring range by means of:
•
extremely loose surfaces of bulk solids, e. g. bulk solids with low piled density when
filled pneumatically.
•
Build-up, primarily of moist products.
