Probe end pulse lost
W
The probe end pulse
amplitude is less than the
probe end threshold. This
means the instrument cannot
find the probe end to measure
level in TBF mode. The
instrument uses direct mode
as an alternative to TBF
mode. This error is only
displayed in automatic
measurement mode.
The dielectric constant of the
tank contents is too high.
Check that the measurement

The tank is full. The level or
the interface signal is lost in
the full area. The
measurement is held at the
blocking distance value.
This is also used for
applications with WHG
approval. Danger of overflow!
Remove the contents from
the tank until it is at a safe
level.
Dielectric constant out of
range
W
The dielectric constant,
ε
r
,
calculated by the instrument
is outside the given range.
This only occurs if the
dielectric constant is
automatically calculated (not
set by default).
Check that the probe does not
touch the process connection
(short circuit). Attach the end
of the probe or install it in a
stilling well or bypass
chamber.
