9Overview and application description of the different sensor types
Acoustic trumpet (standard tool)
Straightening tube
The acoustic trumpet bundles incident ultrasonic
waves, thereby extending the range of the device. This
behaviour makes it ideal for medium distances.
The leakage can be heard from large distances, for
precise detection, the user must approach the leakage
and consistently follow the "loudest" point. Individual
compressed air components are then checked for
precise detection.
Quantification distance (distance) 1 –6 m
Use of acoustic trumpet:
•Average distance to pipe/component 0.2 - 6 m
•Low interfering noise
•Leakage freely accessible
•Use at distances of up to 6 metres if no
parabolic mirror available
The straightening tube permits only very few ultrasonic
waves to pass in the direction of the ultrasonic transducer,
allowing leakages to be located very precisely.
For this reason, the use of the straightening tube is
recommended for small distances, for the precise detection
of the corresponding leakage.
Quantification distance: 0…0,2 m
Use of focus tube:
•Short distance to pipe/component 0.05 m
•Pipe/component freely accessible
•Pipes and components to be inspected are very
close together
•Medium to high noise
•Use when no gooseneck available
Gooseneck
Parabolic mirror
The gooseneck should be used if the pipes and
components to be inspected are physically very close.
In addition, the shape of the gooseneck can be flexibly
adapted to easily inspect hard-to-reach pipes and
components.
The sensitivity of the gooseneck has been reduced to
dampen noise. This makes it ideal for target-ed, local
testing of compressed air components at high noise
levels, for example in systems using pneumatic
cylinders and in compressed air distribution cabinets
Quantification distance →0 …0.05m
Use of gooseneck:
•Short distance to pipe/component 0.05 m
•Leakage not freely accessible
•Medium to high ultrasonic noise
•Pipes and components to be inspected are
very close together
The parabolic mirror bundles horizontally incident
ultrasound in its focal point where the ultrasonic transducer
is located. On the one hand, this leads to a considerable
amplification of the measured ultrasound (high range) and,
on the other hand, to a very precise directional behaviour,
since ultra-sound that does not incident horizontally is
reflected by the reflector.
The combination of these two characteristics enables the
parabolic mirror to precisely locate leaks at large distances.
Quantification distance →3 –12 m
Use of parabolic mirror:
•Large distance to pipe/components 3 –15 m
•Interfering noise
•Leakage not freely accessible (behind a fence)
•Near leaks (superimposition))

Device components and controls
LD500 V2.03 Seite 10 von 67
9.1 Assembly with acoustic trumpet
The acoustic trumpet allows acoustic amplification by bundling the sound waves and specifies the
location of the leak. Due to the special construction of the integrated laser pointer is still usable. The
camera is integrated on the bottom of the acoustic trumpet and is electrically connected to the
preamplifier module via the jack plug.
Assembling is done by plugging the individual components until easy locking audible (plug in to the
stop).
The components are removed in the reverse order; for unlocking the preamplifier module, the release
button must also be pressed.
9.2 Assembly with focus tube with focus tip
The focus tube with focus tip is used to detect very small leaks, to accurately locate them.
Just like the acoustic trumpet, the tube can be plugged into the preamplifier with ultrasonic receiver.
The use of the camera is no longer possible.
The components are removed in the reverse order; for unlocking the preamplifier module, the release
button must also be pressed.

Device components and controls
LD500 V2.03 Seite 11 von 67
9.3 Assembly with Gosseneck
Due to its flexibility, the gooseneck tool is used for punctual measurements in hard-to-reach areas.
Connection to the LD 500 is via the supplied spiral cable, see Figure 10.
It is no longer possible to use the camera.
To remove the component, remove the connection cable by pressing the release button on both sides
and pulling off the cable.
9.4 Assembly with Parabolic mirror
The parabolic mirror is used for measurements at greater distances as well as for high requirements
regarding selectivity and location of leakage positions.
Connection to the LD 500 is via the supplied spiral cable, see Figure 11.
To remove the component, remove the connection cable by pressing the release button on both sides
and pulling off the cable.
Note: To use the parabolic mirror and gooseneck, these components must be activated in the LD 500
during initial commissioning in order to save the component-specific adjustment parameters. If
this has not already been done ex-works, the data for this is supplied via USB stick. For the
activation (parameter import), see chapter 11 Operation here in Sub chapter "Export / Import".“.

10 Start-up / / Application LD 500
Please first observe the safety instructions in Chapter 2
10.1 Switch on
Hold down the power button for about 1 second, the power will turn on, and a start-up sequence will
appear on the display. Pressing the button again switches the device off again.
On-Off button, see device components and controls
10.2 Headphone Volume Up / Volume Down
The volume up and volume down buttons in the headset can be increased or decreased in 16 steps.
Continuously pressing the button automatically increases / decreases the value.
Volume up / down buttons for headphone volume, see device components and controls
Please make sure the headphone level is <50% before putting on the headphones.
10.3 Sensitivity level
Ultrasound levels can be understood as a "loudness" of the leakage.
With the “Sensitivity" button, the sensitivity of the LD500 can be adjusted to the environment, which
strongly influences the acoustic behaviour of the device and increases or decreases the valid value
range. A reduction in sensitivity reduces the range of the leakage reading but the "responding area",
indicated by the circle in the display, also gets smaller, which considerably simplifies detection.
Sensitivity levels
0 –60 dB = Highest sensitivity level of the device (use with small leaks and no noise), selection with the
"HiSn" button or the "Sensitivity" button
10 –70 dB = Leakages and noises get "less noisy", the range is reduced.
20 –80 dB = Leakages and noises get "less noisy", the range is reduced.
30 –90 dB = Leakages and noises get "less noisy", the range is reduced.
40 –100 dB = Most insensitive stage (large leaks, many noises →for heavy-duty application)
By default, the LD500 is set to the auto function and will automatically switch between levels (10 –70 dB
to 40 –100 dB).
10.4 Laser On/Off
The laser pointer can only be switched on or off via the laser on / off button in the display (not via
the membrane keypad). When switched on, the display shows a laser warning symbol.
