Out of specification (NE 107 status signal)
Signal weak The signal amplitude is less than the
average value. This can occur if the
liquid is agitated or if there is foam in the
tank. If this error occurs frequently, the
device will possibly show the "No
measuring value" error message. 1
If this error occurs frequently, it is possible that you
must install a float with a radar target (if there is no
float supplied with the device).
Signal strong This error can occur if there is a large
change in signal amplitude. 1
No corrective action is necessary.
Spectrum quality
bad
The quality of the spectrum is poor. If
this message is temporarily shown, this
will not affect the performance of the
device. If this message is continuously
shown, the measured values can be
incorrect. The error message
"Measurement old" will then be shown.
Possible causes are foam, vortices,
turbulent product surface and internal
tank elements.
Do a check of the device, tank and the process. Change
the device settings. If necessary, contact the supplier.
