Description
The measurement value is less
2
than the minimum value of the
current output range. The current
output cannot go lower than its
minimum value and thus does not
agree with the correct
measurement value.
The measurement value is more
2
than the maximum value of the
current output range. The current
output cannot go higher than its
maximum value and thus does not
agree with the correct
measurement value.
The signal amplitude is too small.
The measurement value is
incorrect and does not change for
more than 10 s.
The empty spectrum recording
does not agree with the process
conditions at this time (e.g. the
tank height was changed).

Corrective action
Do a check of the process
conditions and the minimum
current output value.
Do a check of the process
conditions and the maximum
current output value.
Make sure that the device
installation agrees with the data in
the handbook.
If the message is shown again, it is
possible that a different antenna
must be installed. tell the
supplier.
Make sure that the device
installation agrees with the data in
