4 This menu item does a continuous check for radar reflections between the blocking distance (value set in menu item
2.3.2) and the flange. But condensation or other sources of parasitic signals can cause an "overfill" error. If you set
this menu item to "YES", make sure that there are no sources of parasitic signals near to the flange.

Function
Function description
OVERF. ENAB.
If this function is in operation,
the device will monitor the
level even if it is in the
blocking distance. The
reading shown on the display
stays fixed at the blocking
distance if the level is higher
than the blocking distance.
The output will show that the
tank is full. An error is
recorded by default.
If this function is not in
operation, the device looks
for the largest signal between
the process connection and
the tank bottom.
MULT.REF.EN.
Multiple reflections will cause
the device to display smaller
level readings. Objects in the
tank, sharp corners,
installation of the device on a
large nozzle or at the centre
of a dome roof, and low
dielectric products (ε
1.8...5) can cause multiple
reflections. A very calm
surface or a tank with a small
convex or flat roof can also
cause multiple reflections.
If this function is in operation,
the device looks for the first
signal peak below the
process connection. This
signal peak is then used to
measure the level of the tank
contents. If this function is not
in operation, the device looks
for the largest signal below
the process connection.

stop the empty spectrum
