04 Start-up and application
The LD6000 PTS transmitter unit is running on a customary
9 V battery. The Bluetooth headphones, Bluetooth speak-
er and Bluetooth receiver are provided with an integrated
rechargeable battery. Before start-up make sure that the
devices are charged or the battery has sufficient voltage.
Overview of the functions of the LD6000 PTS transmitter
unit.
LD6000 PTS
The functions of the Multi-function button (5) are described
below.
• If the button is pressed for approx. 3 seconds while
switched off, the transmitter unit switches on.
• If the button is pressed for approx. 6 seconds while
switched off, the last active Bluetooth connection will be
deleted. Simultaneously the device switches over into
pairing mode (search mode).
• If the transmitter unit is switched on and a Bluetooth
connection is established, briefly pressing the button
activates the "mute"function (muting). If the "MUTE"LED
is illuminated, sound transmission is active. If the LED is
not illuminated, the transmission is muted as well. The
level indicator is not affected by this.
• To switch the device off, press the button for approx. 3
seconds. All parts of the "Level LED"light up. The device
only fully switches off when letting go of the button.
The Battery LED (2)indicates the battery's voltage condi-
tion. If the LED is constantly lit, the battery has sufficient
voltage. If it flashes slowly, the battery should soon be
changed. If it flashes quickly, the voltage is insufficient for
another measurement and the battery has to be changed
first.
The Bluetooth LED (3) indicates, whether there is a Blue-
tooth connection. If the LED is constantly lit, a connection
is established. If it flashes, the device is in pairing mode
(search mode). If it is not illuminated, the connection is not
made and the transmitter unit will only reconnect (pair) with
the last active connection.
The Level LED (4) indicates the intensity of the recorded
sound. Please note that a leaking sound does not necessar-
ily cause a full-scale deflection of the Level LED. The Level
LED is only intended for orientation purposes.

Operating manual for LD6000 PTS
The "MUTE" LED (6) indicates, whether the recorded sound
is transmitted or the transmission is muted. If the LED
is illuminated, the sound is transmitted. If the LED is not
illuminated, the transmission is muted.
The two integrated 9 mm connectors (1) serve to connect a
frequency generator (e.g. SeekTech transmitter ST510) for
pipe detection. If a connector is connected to the generator
and at the same time a ground spike is used, the course of
the inserted fibre optic cable can be traced. If both connec-
tors (signal and ground) are connected, the search pig at the
probe tip is contacted. Thus an exact position for the pig can
be determined. The pig was optimized for use with 33 kHz.
Other common frequencies can only be used to a limited
extent or not at all.
To install the LD6000 PTS in a pipeline to be inspected,
please proceed according to the illustrated getting started
guide which is supplied with the device. The above
mentioned usage is only one example for possible applica-
tions. For different application scenarios the procedure is
to be analogous. In chapter 8 Application examples you will
find further possible uses of the LD6000 PTS.

Operating manual for LD6000 PTS
4.2 Disinfection – disinfection instructions
mBefore using the LD6000 PTS, all parts coming
into direct contact with the drinking water must
be disinfected. Proceed according to the following
instructions.
mAlways wear suitable protective gloves (supplied
in the accessory case) when filling the storage
container or refilling the spray flask.
The disinfectant is a neutral, liquid cleaning agent based
on especially stabilized 3% hydrogen peroxide. It is used
for environmentally friendly cleaning and sterilization and
approved for use in drinking water systems.
mNo general HAZMAT regulations apply. However,
the usual precautions are to be taken when
handling chemicals.
1. First spray a generous amount of disinfectant on
the sensor head of the LD6000 PTS and let it sit for
approx. 5 minutes.
2. Fill the storage container to approx. ¼ with disinfectant.
3. When measuring, the storage container is to be
positioned vertically at the top to enable a continued
flow of the disinfectant.
When inserting the fibre optic cable into the pipeline, it is
continuously pulled through the disinfectant solution. No
specific application time is required during insertion. The
agent is pH neutral and after use can be fed into the waste
water system without prior neutralization.
4.3 Connection of the LD6000 PTS cable passage
The cable passage is connected for a smooth insertion
of the flexible sensor head in the drinking water line. The
passage comes with a GEKA coupling approved for use in
drinking water systems. Prior to installation the water line
must be shut off!
Close the shut-off valve and then prepare the end of the
pipe section to be examined with a supplied GEKA coupling.
Always connect preferably straight pieces or branches of no
more than 45° to avoid the sensitive sensor head getting
caught during insertion.
If the distance between the attached GEKA coupling at the
pipeline and the next shut-off valve is too small, you should
use a hose adapter (supplied in the accessory case) to
connect the cable passage.
The GEKA coupling is now connected to the pressure-
resistant cable passage of the LD600 PTS.
Make sure that the storage container with the disinfectant
(see disinfection instructions 4.2) is positioned vertically at
the top.

A - 5 EN
Operating manual for LD6000 PTS
Before inserting the sensor head with the fibre optic
cable from the reel, the shut-off valve must again be opened
completely.
mBefore opening the shut-off valve make sure that
all connections have been made correctly.
4.4 Insertion of the fibre optic cable
m In case of DN50 pipes the fibre optic cable can
be pushed around bends of 90°. Despite this
flexibility and the high breaking load, one has to
exercise utmost caution during every application
with 90° turns.
Should the probe get caught, try loosening it by careful
pushing and pulling. In the course of the insertion process
a very loud scratching noise will be audible via the head-
phones/speaker, which is a result of the pushing. This can
be suppressed by use of the MUTE function.
05 Acoustic leak detection
The fibre optic cable with integrated sensor head for audio
recording is inserted in the defective pipe. The sound
recorder is very sensitive and records even barely percep-
tible sounds. Nevertheless, despite this sensitivity, it can-
not be excluded that a leak is not recognized under certain
conditions. This might either be due to the fact that the leak
causes no leakage noise or else the sensor head no longer
works correctly. Hence, prior to every insertion, check
whether the sensor head records the sounds correctly by
running you finger down the tip.
It is recommended to insert the fibre optic cable in steps of
approx. 30-50 cm. At the end of each step, the probe should
be allowed to come to a rest in order to record the sound in
the probe's environment.
5.1 Using the Bluetooth headphones
LD60 00 PT S
In the case of leak detection using the LD6000 PTS in
connection with the Bluetooth headphones, the noisiest spot
in the defective pipe is the search target. We proceed on the
assumption that every leak brings about a leakage noise.
The closer you get to the fault location, the more sound
energy will be recorded by the sensor head, which in turn
results in a perceptible increase of the volume. At the same
time a shift in the pitch to higher frequencies will be audible.
Push the probe so far into the pipe until you have detected
the noisiest location. For fine tuning push and pull the probe
past the leak for a number of times.
5.2 Via integrated level indication
The integrated level indicator at the LD6000 PTS is merely
for orientation purposes. Please note that a leaking sound
does not necessarily cause a full-scale deflection of the
Level LED. On principle, though: the closer the sensor is
pushed to the point of leakage, the more noticeable will be
the deflection.
5.3 Using the Bluetooth receiver and LD6000 combina-
tion detector
LD60 00 PT S
LD600 0 PTS
When combined with the LD6000 combination detector
the LD6000 PTS is the perfect visual addition for acoustic
leak detection. By use of the LD6000 combination detector
frequencies to 4000 Hz can be visualized. Optimum results
can be achieved in "smart mode"and here in the user-
defined application. Also recommendable are non-stop
measurements. For details regarding the settings please

EN A - 6
Operating manual for LD6000 PTS
read the user manual of the LD6000 combination detector.
Fundamentally, here, too: the closer you get to the fault
location, the bigger the sound level (numeric indication
in the LD6000 combination detector). At the same time a
shift in the pitch to higher frequencies will be visible (lower
frequency-response diagram in the LD6000 combination
detector).
06 Pipe and pinpoint location
Described below are 2 methods to determine the position of
the probe head. For one thing by using a common locating
device (not included in the scope of delivery) and for
another by means of a perambulator.
Method 1 – locating device
A common locating device is required for pipe and pinpoint
location (not included in the scope of delivery). Typically
such a locating device consists of transmitter and receiver.
Read the operating manual of your locating device for
proper usage.
After successful acoustic leak detection leave the fibre
optic cable at that position in the defective pipe where you
detected the maximum level. Then connect the frequency
generator of your locating device to the LD6000 PTS.
Generally true for all frequency generators of
locating devices:
Probe detection
When one connector is connected to the generator
and the other to a ground spike stuck into the earth,
the course of the inserted fibre optic cable can be
traced.
Locating pinpoints
When both connectors (signal and ground) respectively
are connected to the generator, only the search pig at the tip
of the probe will be contacted. Thus an exact position for the
pig can be determined.
The locating function was optimized for the use with 33 kHz,
othercommonfrequenciescanonlybeusedtoalimitedextentor
not at all.
33 kHz
33 kHz
Method 2 – perambulator
After successful acoustic leak detection also leave the fibre
optic cable at that position in the defective pipe where you
detected the maximum level. Now read the developed
uncoiling length from the mechanical metre counter.
Memorize the value and then walk down the corresponding
length with a perambulator. The position, where the values
of perambulator and mechanical metre counter coincide,
corresponds to the location of the probe head inside the
pipe.
