 Setup → Signal quality
Displays the signal quality of the evaluated echo.
Meaning of the display options
• Strong
The evaluated echo exceeds the threshold by at least 10 mV.
• Medium
The evaluated echo exceeds the threshold by at least 5 mV.
• Weak
The evaluated echo exceeds the threshold by less than 5 mV.
• 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/interface echo
these two, the quality of the end-of-probe 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 (→  142) = Alarm.
• S941, if another option has been selected in Output echo lost (→  142).
