Commissioning
To turn on, briefly press the
I/O pushbutton
. The I/O LED is lit green when the
device is turned on. To turn the device off, press the button until the LED goes out.
The microphone's storage place
is fitted with a magnetic switch. As a result, the
Power transmitter "knows" whether the microphone is currently in use or not.
As long as the microphone rests in its storage place, the Power transmitter remains in
"Stand-by" mode. The internal analogue radio module stays off as no measuring data
needs to be transferred to the Correlator. This saves battery power.
As soon as the microphone is taken from the storage place, the Power transmitter
switches from "Stand-by" to "Active" mode. The radio module is activated. From now on,
the recorded data are directly sent to the Correlator. The row of LEDs switches from
green to red and represents the recorded noise level.

Installation
The sensors should be installed directly on the pipe but, however, you can also attach
them to valve rods or hydrants, for example, or any other position along the pipeline that
is easily accessible.
There must be the best possible contact between the sensor foot or the mounted
adapter (see below) and the pipe. If need be, clean the contact point thoroughly
(preferably with a wire brush).
In some situations it might be helpful to use one of the supplied magnetic angle
adapters.
