13. Troubleshooting
Acoustic Leak Detection – List of possible errors or faults:
Error/Fault Description
Possible Cause
Recommended Action
No sound in the
headphones
1. The sound receiver or the
headphones are not
connected properly
Check the connections between the connected sound receiver and the
connected headphones and the Aqua M300.
2. Incorrect filter settings
Select a broader frequency range, e.g. 50Hz to 2,000Hz and generate a
clearly audible sound by scratching the surface or turning on a radio, for
example. If the action you have carried out causes the numerical or bar
display to change and these sounds can be clearly heard in your
headphones, then you can be sure that the headphones and
microphones are working properly.
Now carry out the measurement again and adapt the frequency range
to suit the measuring operation.
3. The cable which connects
the sound receiver and the unit
appears to be defective
Check the connections between the connected sound receiver and the
Aqua M300. Replace the cable with a spare cable, if possible, or use
the cable from a second Aqua M300 and check if the sound receiver is
working properly.
4. The cable between the
headphones and the central
unit seems to be defective (in
such a case the sound level
indicator on the display works
properly!)
Check the connections between the connected headphones and the
Aqua M300. Connect a spare pair of headphones which you may have
or another pair from a second Aqua M300 to the unit and check the
function again.
5. Memory settings
If the actions you have carried out have not been successful, go to
“Clear Memory"
in the menu

and clear the parameter memory
.
If you can still not hear anything over the headphones, please contact
