1.1 Use
The SeCorrPhon AC 06 is used for electroacoustic water leak
detection and acoustic pipeline location. It can also detect leaks
in underground pressure line systems by correlation.
CAUTION!
To comply with FCC RF exposure compliance re-
quirements, a separation distance of at least 20 cm
must be maintained between the antenna of the
transmitter RT 06 and all persons.
The antenna used for this transmitter must not be
co-located or operating in conjunction with any other
antenna or transmitter.
1.2 How electroacoustic water leak detection works
The SeCorrPhon AC 06 is used to detect water leaks by
electroacoustic means. The device is used in conjunction with
various microphones which are listed in section “Accessories”.
When pressure pipelines leak, water gushes out of the crack into
the ground.
The consequences:
The pipe material begins to vibrate at the leakage point. These
vibrations are transmitted by the pipe and can even be felt at
distant contact points, e.g. ttings. The SeCorrPhon AC 06 makes
this structure-borne sound audible.
The water jet and the pipe in the vicinity of the leak also cause
the ground to vibrate. These vibrations are transmitted through
the ground to the earth’s surface where they manifest themselves
as ground noise.
The human ear continues to play a crucial role in electroacoustic
leak detection. With the right training, it can compare the type and
sound of different noises and distinguish between the noise of a
leak and background noise.

1.3 How acoustic pipeline detection works
Plastic pipes cannot be located by conventional electromagnetic
means because they are not electroconductive.
The acoustic method of locating pipes applies a different principle:
Pipes transmit mechanical vibrations better than the surrounding
ground. When the pipe is caused to vibrate appropriately, these
vibrations are transmitted along the pipe and then through the
ground to the earth’s surface. Here they can be picked up using
a ground microphone and the corresponding receiver with
headphones according to the water leak detection principle.
Just like with water leak detection, the pipeline is usually wherever
the greatest intensity is detected. Fiber cement pipes and metal
pipes can also be located in this way.
If you want to locate pipes by acoustic means, follow the operating
instructions for the vibration detector (e.g. COMBIPHON). To
locate the pipe, proceed as you would when detecting a water
leak. The SeCorrPhon AC 06 offers an extra mode to help you
locate the pipeline (see section 3.4).
1.4 How correlation works
Sensitive microphones record the noise from leaks at accessible
ttings and transmit them by radio to the correlator.
The SeCorrPhon AC 06 then calculates the position of the
leak using Fast Fourier Transformation (FFT = mathematical
calculation rule).
Additional functions allow you to, for example, improve the leak display,
enter several sections of pipe or measure the sound velocity.
Radio transmitter RT 06 can automatically measure the input level
of the microphone and optimally adjust its amplier modulation
accordingly. Features such as the microphone used, the battery
condition and the amplier setting are transmitted to the correlator
by radio data where they are analyzed. This ensures optimal results
in all situations with maximum ease of use (switch on by plugging in
the microphone).
Note:
These operating instructions refer to the SeCorrPhon
AC 06. They explain the functions of software
version 1.X. The manufacturer reserves the right
to make technical changes..

2 Starting up
2.1 Starting up for the rst time
CAUTION!
The batteries of the AC 06 and RT 06 must be fully
charged once before starting up for the rst time.
If the batteries are only partially charged, their ca-
pacity and consequently their operating time may
be reduced.
CAUTION!
Safety measures
Do not use the headphones at a high volume.
Hearing specialists warn against using head-
phones at a high volume constantly or for a pro-
longed period.
Set the volume so that you only hear the sounds
at a moderate level.
Disable the headphones as soon as you realize
that interference noise may occur (footsteps,
vehicles etc.).
Disable the headphones when the microphone
is in motion.
Please note that it is more difcult to pick up
sounds in trafc.

If you switch the device on as follows, you will be in what is known
as correlator mode. Certain functions are only possible in this
mode, others are not available.
Attach the two piezo micro-
phones to accessible ttings.
When the round magnet is
screwed onto the piezo micro-
phone, remove the very se-
curely attached round magnet
protector if necessary.
Insert the two microphone con-
nection cables into the sockets
of the RT 06 radio transmitters
(1). If you are only using one
RT 06, you must connect one
microphone directly to the
input (2) of the AC 06.
LED 1 on the RT 06 should
light up green.
Connect the headphones to
the input (3) of the AC 06.
Switch on the AC 06 by hold-
ing down the ON key.
The main screen displaying
the software version number
and the battery capacity will
briey appear.
Next the main screen (see
inside cover). From here you
can go to the menu (menu
key) or perform one of the
functions.
To switch the appliance off,
hold down the ON key until it
responds.

2.3.2 Radio transmitter RT 06
Radio transmitter RT 06 can
be operated with various sen-
sors, EM30 microphones and
the HA hydrophone. It is rec-
ommended to use active lter
ZF01 if you want to lter out
interference noise or if you
only want to transmit a certain
acoustic frequency range to
correlator AC 06.
CAUTION!
Always connect the sensor to the measuring point
rst (connect microphone to slide gate, hydrants
etc.) before switching on the RT 06 by plugging the
sensor into the socket (2).
This ensures that the automatic amplication in the
RT 06 is set quickly and correctly.
The RT 06 is switched on by plugging the sensor into the socket
(2).
Always press the lter key (4) for plastic piping. The right LED
(5) lights up to indicate the switch. At this setting only the lower
frequencies (low pass) are transmitted to the correlator by radio.
This often increases the quality of the correlation measurement.
Every time the RT 06 is switched on all frequencies are transmit-
ted and the left LED (6) lights up.
The carrying knob attached to the top of the aerial is ideal for
transportation.
The LED (1) indicates the status of the RT 06:
Operation: green
Undervoltage: ashing red
Charging: 1 x ashing green
Buffering: 2 x ashing green
Not charging: red (because temperature below 0 °C)
