Electroacoustic water leak detection

To deactivate the

AC 06

re-

lease the

rotary regulator

press the

microphone key

again.

If the

AC 06

does not go off

when you release the rotary

regulator, the function of the

rotary regulator has been

changed. In this case press

the rotary regulator again.
Place the test rod at the next

measurement location and

proceed as above.

The previously measured

value will now appear in the

small digital display for com-

parison purposes.
