tery fluid. If contact with battery
fluid is made, rinse the affected
areas immediately with plenty of
clean water and seek medical
attention straight away.
►If batteries are damaged or used
incorrectly, vapours can be emit-
ted. Ventilate the area with fresh
air and seek medical attention
if you feel unwell. The vapours
could irritate the respiratory
system.
CAUTION
Possible material damage if bat-
teries are used incorrectly.
Proceed in accordance with the fol-
lowing information to avoid material
damage:
►Use only the battery type ap-
proved by the manufacturer.

Function description
How it works
LEAKPEN is an acoustic measure-
ment device. A vibraphone picks up
noises from the water pipes under
inspection. The measurement results
are shown numerically on the display
and transmitted acoustically through
headphones.
The measurement device and head-
phones can be connected via Blue-
tooth or with a cable.
The loudest noises reveal the location
of the leak. Extraneous noises can be
cancelled using high- and low-pass
filters.
Either disposable batteries or re-
chargeable batteries can be used to
power the measurement device.
Preparations
Setting up the power supply
The measurement device can be
operated by means of disposable
batteries/rechargeable batteries.
For permissible types, see Technical
specifications.
CAUTION
Damage to electronic components.
Incorrect set-up of the power supply
for the measurement device can
cause damage to electronic compo-
nents and other parts of the device.
►Only remove disposable batter-
ies/rechargeable batteries once
the measurement device has
been switched off.
►Make sure that the polarity is
correct when inserting the bat-
teries.
Proceed as follows to insert the bat-
teries:
– Unscrew the tip of the measure-
ment device (9).
– Insert the batteries into the bat-
tery compartment and make sure
that the polarity is correct (the
positive terminal on the battery
should always be inserted first).
– Place the tip of the measurement
device (9) correctly on the battery
compartment and screw it back on.
To remove the batteries:
– Unscrew the tip of the measure-
ment device (9).
– Either pull the batteries out of the
measurement device or tap the
measurement device lightly on
the palm of your hand and shake
them out.
Preparing the working area
In order to achieve optimum and relia-
ble measurement results:
– The working area should be free
from dirt and contamination.
Check the measuring point and vi-
braphone and clean as necessary.
– There must be enough space
in the working area around the
measuring point to allow the vibra-
phone to be positioned correctly
with respect to/properly connect-
ed to the area under inspection.
Check whether there is enough
space and adjust if necessary.
– There must be enough space in the
operator's working area in order to
guarantee safe, optimum operation
of the measurement device.

11
– If used on busy roads, ensure
sufficient visibility (warning triangle,
reflective vest).
Preparing the measurement device
for use
– Switch on the measurement de-
vice using the ON/OFF button (6).
– Touch the vibraphone to check
that it is working properly. The
smallest of vibrations must be
shown on the display.
Use
General procedure
The monitoring procedure is used to
isolate and pinpoint the leak site:
– For structure-borne sound meas-
urements, place the vibraphone
on the measuring point under
inspection (pipe, valve, hydrant,
etc.). The noise level will be
shown on the display (3).
– Repeat the measurement at var-
ious locations along the pipe in
order to isolate the noise source.
– The louder the measured noise,
the closer the leak site.
– If no noise can be heard, it can
be assumed that the pipe section
under inspection is intact.
Switching the device on and off
To switch on:
– Press the ON/OFF button (6).
This switches on the measure-
ment device and the measure-
ment screen will be shown on the
display (3).
To switch off:
– Press and hold the ON/OFF
button (6).
This switches off the measure-
ment device and the display will
disappear.
INFORMATION
►If the measurement device is
switched on but then not used,
it switches off automatically after
10 minutes.
Using headphones
INFORMATION
►Read the operating instructions
for the headphones.
►The measurement device and
headphones must be paired with
each other.
►The measurement device and
the headphones are already
paired on delivery.
– Charge the rechargeable batter-
ies in the headphones.
– Switch on the headphones.
– Switch on the measurement
device in order to connect the
headphones to the measurement
device.
– Set the volume using the and
buttons.

12
– The measured values are shown
on the display and also transmit-
ted as acoustic signals through
the headphones. The value on
the display is independent of the
selected volume.
If the headphones used are not the
same as those used for the previous
connection, or if the headphones
have been connected to another
device, then the measurement device
and the headphones must be paired
again. To do this, see the "Connect-
ing headphones" section.
Setting the volume
– By pressing the ON/OFF button
(6), you can switch the sound on
and off (mute).
– Press the or button to re-
spectively reduce or increase the
volume when the measurement
screen is on the display.
– When you press the ON/OFF
button (6) to switch off the
device, your chosen volume is
saved.
To protect your hearing in the event of
loud noise, the measurement device
has a hearing-protection feature. By
selecting the protection level, the
maximum volume can be set (for
more information, refer to the section
entitled "Setting the hearing-protec-
tion level"). When the hearing-protec-
tion feature intervenes, the volume
is limited. This is indicated by the
hearing-protection symbol (33). The
symbol goes out as soon as the vol-
ume drops below the set protection
level.
Setting the filter
The measurement device can cancel
high- or low-frequency interference by
activating high- or low-pass filters.
– You can choose the filter you
require by pressing the button
on the measurement screen. If
the filters are switched on, the
filter symbol (35 or 36) will be
shown on the display.
The measured value changes de-
pending on the filter settings.
Backlighting
– Press the button to switch the
backlighting/leakage LED on or
off.
Torch
– Press and hold the button to
switch the torch feature on or off.

13
Leakage LED
– Press the button to switch the
leakage LED/backlighting on or
off.
The leakage LED provides a visual
indication of the noise level in case
the display is not visible because the
measurement device is being used
elsewhere for measuring purposes,
e.g. if it is being used in a shaft. The
leakage LED is able to indicate three
different statuses (see the section
entitled „Setting the threshold value
for the leakage LED“):
LED off If the LED is off, this
means that the noise level
is below the lower thresh-
old value.
LED flashing If the LED is flashing, this
means that the noise level
is either equal to the upper
or lower threshold value,
or lies between these
values. The faster the LED
flashes, the louder the
noise level.
LED
continuously
lit
If the LED is lit continu-
ously, this means that the
noise level is above the
upper threshold value.
Configuration
Pairing the headphones
INFORMATION
►Pairing is always required when
the headphones used are not
the same as those used for the
previous connection or if the
headphones have been con-
nected to another device.
►On delivery, the measurement
device and the headphones are
already paired.
– Switch off the measurement
device or check that it is already
switched off.

are in pairing mode (see the
operating instructions for the
headphones). As a rule, this is
achieved by pressing and holding
the ON button and indicated by
two-colour flashing.
– Press and hold the button.
– Switch on the measurement device
by pressing the ON/OFF button (6).
– Release the button.
– The measurement device will now
search for new headphones and
establish the connection. The
search can take up to 30 seconds.
Setting the hearing-protection level
– Switch off the measurement
device or check that it is already
switched off.
– Press and hold the button.
– Switch on the measurement
device by pressing the ON/OFF
button (6).

– The current protection level will
be displayed.
– Press the volume-reduction
or volume-increase button to
select the "Quiet" (1), "Medium" (2),
"Loud" (3) or "Hearing protection
off" (4) setting.
– When you press the ON/OFF
button (6) to switch off the de-
vice, your chosen protection level
is saved.
