code Description
W The quality of the spectrum is
poor. If this message is
temporarily shown, this will
not affect the performance of
the instrument. If this
message is continuously
shown, the measured values
can be incorrect. The error
message "Measurement is
old" will then be displayed.
Possible causes are foam,
vortices, turbulent product

elements.
W The Empty Spectrum stored
in the instrument does not
agree with the installation. If
you change the instrument
configuration (tank height

displayed. The recorded

displayed.
