Acoustic tube probe LD6000PTS 50m / LD6000PTS 80m / LD6000PTS 100m / LD6000PTS 150m
Information about the device
Device description
The devices LD6000PTS 50m, LD6000PTS 80m,
LD6000PTS 100m and LD6000PTS 150m are used for
acoustic leak detection in a pressurized water line, also on
the house connection side. For this purpose, the devices
have a bendable pig probe with integrated precision
microphone and a contactable probe cable.
Leakage sounds can be transmitted to the corresponding
headphones via Bluetooth and rendered audible. The sound
level is displayed analogously on the device.
The exact leakage position can be determined with a
mechanical metre counter.
Using the separately available combination detector LD6000
with Bluetooth receiver LD6000PTS, frequencies can be
visualized and points of leakage can be indicated in form of a
bar graph.
A separate frequency generator (not included in the scope of
delivery) in the 33kHz range allows the entire fibre optic cable
or the probe tip to be contacted. With a suitable receiver, the
pipeline course can be detected and the leakage point located
with pinpoint accuracy.
The devices are suitable, for example, for use on the following
elements of a piping system:
• domestic water meter
• free-flow valve
• dismantled piping
• tapping saddle
• hydrant
The images in these instructions show the device
LD6000PTS 50m by way of example.

Transport and storage
Note
If you store or transport the device improperly, the
device may be damaged.
Note the information regarding transport and storage of
the device.
Transport
Use the matching transport case to transport the accessories in
order to protect the accessories from external influences.
Before transporting the device, proceed as follows:
• Lock the storage container for the disinfectant in place by
means of the rubber strap provided at the reel.
• Make sure that the device does not suffer any severe
shocks during transport.
The supplied Li-ion batteries are subjects to the requirements of
dangerous goods legislation.
Observe the following when transporting or shipping Li-ion
batteries:
• The user may transport the batteries by road without any
additional requirements.
• If transport is carried out by third parties (e.g. air transport
or forwarding company), special requirements as to
packaging and labelling must be observed. This includes
consulting a dangerous goods specialist when preparing
the package.
– Only ship batteries if their housing is undamaged.
– Please also observe any other national regulations.
Storage
When the device is not being used, observe the following
storage conditions:
• dry and protected from frost and heat
• protected from dust and direct sunlight
• the storage temperature complies with the values specified
in the Technical data
• Batteries are removed from the device
• Always store the disinfectant in an upright position (lid
facing up).

Start-up
Inserting the batteries into the transmitter unit
Note
Make sure that the surface of the device is dry and the
device is switched off.
1. Remove the battery compartment cover from the
transmitter unit.
2. Use the battery clip to connect the new battery with correct
polarity.
3. Slide the battery compartment cover back on the
transmitter unit.
Disinfecting the device
Caution
The disinfectant is a neutral, liquid cleaning agent
based on specially stabilized 3% hydrogen peroxide.
Always wear suitable protective gloves when filling the
storage container or the spray bottle.
Note
Before usage, all device parts coming into contact with
drinking water must be disinfected.
When inserting the fibre optic cable into the pipeline, it is
continuously pulled through the disinfectant solution. There is
no need to observe a specific exposure time during insertion.
The agent is pHneutral and can be fed into the waste water
system without prior neutralization after use.
1. Spray the sensor head(3) with the disinfectant(9) and
leave it to act for approx.5minutes.
2. Fill the storage container(1) to approx.¼ with disinfectant.

Connecting the cable passage
The cable passage(2) is connected for a smooth insertion of the
flexible sensor head(3) in the drinking water line. The passage
comes with a Geka coupling approved for use in drinking water
systems.
1. Close the shut-off valve of the water line.
2. Prepare the end of the pipe section to be examined with a
supplied Gekacoupling(16, 17).
ðConnect preferably straight pieces or branches of 45° to
avoid the sensor head from getting caught during
insertion(3).
3. If the distance between the attached Gekacoupling and
the next shut-off valve is too small, use the optional hose
adapter(11) to connect the cable passage.

4. Connect the Gekacoupling to the cable passage(2).
ðMake sure that the storage container with the
disinfectant(1) is positioned vertically upwards.

Inserting the sensor head
Note
In case of DN50pipes, the fibre optic cable can be
pushed around bends of 90°. Despite this flexibility,
please proceed with extreme caution during any
application with 90°bends due to the high breaking
load.
Info
The sound recorder is very sensitive and records even
barely perceptible sounds. Nevertheless, despite this
sensitivity, it cannot 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(3) no longer works
correctly. Therefore, check the sensor head prior to
every measurement by running your fingernail over the
tip.
Info
In the course of the insertion process, a very loud
scratching noise can be heard in the headphones/
speaker, which is caused by the pushing. You can
mute the sound using the multifunction button(21).
1. Before opening the shut-off valve, make sure that all
connections have been made correctly. Then slowly open
the shut-off valve.
2. Carefully slide the sensor head(3) into the pipe through the
connected cable passage(2).

EN 11
Acoustic tube probe LD6000PTS 50m / LD6000PTS 80m / LD6000PTS 100m / LD6000PTS 150m
3. Push the fibre optic cable(6) further into the pipe in
increments of 30 to 50cm. Allow the sensor head(3) to
come to a rest at the end of each step in order to record
the sounds in the environment of the sensor head.
4. If the sensor head(3) gets stuck inside the pipe, try to
loosen it by carefully pushing it back and forth.
Acoustic leak detection with Bluetooth headphones
In the case of leak detection 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(3),
which results in a perceptible increase in volume. At the same
time a shift in the pitch to higher frequencies will be audible.
1. Push the sensor head(3) into the pipe until you have
located the spot with the loudest noise and the highest
pitch.
2. For fine tuning, push and pull the sensor head(3) past the
spot you have just determined for a number of times.
ðThere is a leakage at the defined spot.
Acoustic leak detection with level indicator
Info
The integrated level indicator is for orientation
purposes only. A leaking sound does not necessarily
cause a full-scale deflection of the LevelLED(22).
1. Gradually push the sensor head(3) into the pipe.
ðThe more of the LevelLEDs(22) light up, the closer the
sensor head(3) is to the leakage.
Acoustic leak detection with Bluetooth receiver and
LD6000combination detector
Info
By use of the LD6000combination detector,
frequencies up to 4000Hz can be visualized.
The best results with the LD6000combination detector
can be achieved in the user-defined application in
smart mode as well as in non-stop measuring mode.
For detailed information on measuring with the
LD6000, see the separate LD6000manual.
The LD6000combination detector is not included in the scope
of delivery and is available as an option.
1. Connect the headphones to the LD6000combination
detector.
2. Connect the Bluetooth receiver(12) to the
LD6000combination detector.
3. Gradually push the sensor head(3) into the pipe.
ðThe larger the numeric display of the
LD6000combination detector and the higher the
pitch(see lower frequency-response diagram of the
LD6000combination detector), the closer the sensor
head(3) is to the leakage.
