Signal quality
Navigation  Diagnostics → Signal quality
Description Displays the signal quality of the level echo.
Meaning of the display options
- Strong:
The evaluated echo exceeds the threshold by at least 10 dB.
- Medium:
The evaluated echo exceeds the threshold by at least 5 dB.
- Weak:
The evaluated echo exceeds the threshold by less than 5 dB.
- No signal:
The device does not find an usable echo.
The signal quality indicated in this parameter always refers to the currently evaluated
echo, either the level echo or the tank bottom echo.
In case of a lost echo ('Signal quality' = No signal) the device generates the following error
message:
'Diagnostic echo lost' = Warning (factory setting) or Alarm, if the other option has been
selected in 'Diagnostic echo lost'.
