Measuring status
Measurement is old W This is a temporary error
message. If the device cannot
get a measurement in this
time limit, the displayed
measurement is no longer
correct. The voltage is
possibly too low. If the device
continues to show the
message "spectrum quality is
bad", then this message is
also shown.
Check the voltage at the
device terminals. Refer also
to the error message
"Spectrum quality is bad".
Level has reached the
blocking distance (silo
overfill)
W The level is in the blocking
distance. There is a risk that
the product will overflow
and/or cover the device.
Remove some of the product
until the level is below the
blocking distance.
Measurement is lost in the
tank bottom
W The silo is possibly empty.
The device will display the silo
bottom measurement.
If you fill the silo, the device
will measure again.
The device got the last valid
measurement near to the silo
bottom, but it can no longer
find the signal. It is possible
that the device cannot find the
bottom of the silo if it is
installed in a silo with a dish-
shaped (DIN 28011 or similar)
or conical bottom. The form
of the silo bottom causes a
delayed radar reflection and
the device will display the
error message
"Measurement is lost in the
tank bottom". The device will
display the silo bottom
measurement.
Follow the instructions on
page 63.
