Signal quality
Navigation Setup → Signal quality
Description Displays the signal quality of the level echo.
Additional information 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 a usable echo.
The signal quality indicated in this parameter always refers to the currently evaluated
echo: either the level echo or the tank bottome echo. To differentiate between these two,
the quality of the tank bottom echo echo is always displayed in brackets.
In case of a lost echo (Signal quality = No signal) the device generates the following
error message:
• F941, for Output echo lost (→ 153) = Alarm.
• S941, if another option has been selected in Output echo lost (→ 153).

performs a mapping.
• Distance unknown
To be selected if the actual distance is unknown. A mapping can not be performed in this
case.
