Function Function description
MEASUR.MODE The device uses the dielectric constant (ε
of the tank contents to monitor level. In
direct mode (if the dielectric constant is
high), the level signal is a reflection on the
surface of the tank contents. If the
dielectric constant is low, the device uses
TBF mode. The device in TBF mode uses the
radar reflection on the bottom of the tank
(the signal goes through the tank contents).
This menu item is set by default to "Direct"
for tank contents with an ε
very low (<1.6), use "TBF Full". If ε

"TBF Partial" is an automatic mode that lets
the device make a selection between "Direct
mode and "TBF" mode. If you use "TBF Full"
or "TBF Partial", enter the dielectric
constant in menu item 2.5.3 Er PRODUCT.

OVERF. ENAB. If this function is switched on, the device will
monitor the level even if it is in the blocking
distance. The displayed output stays fixed at
the blocking distance. An error is recorded
by default.

display smaller readings. Objects in the tank,
sharp corners, installation of the device on a
large nozzle or at the centre of a dome roof
can cause multiple reflections. A very calm
surface or a tank with a small convex or flat
roof can also cause multiple reflections.
