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
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

Operation
LD 450 V1.00 Seite 9von 23
10 Start-up / / Application LD 450
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 LD 450 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 .
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)

Operation
LD 450 V1.00 Seite 10 von 23
10.4 Laser On/Off
The laser pointer can only be switched on by pressing the laser on / off button.
When switched on, the display shows a laser warning symbol.
11 Operation
The operation is largely self-explanatory and menu-driven via the touch panel.
The selection of the respective menu items occur via short "tapping" with the finger or a soft round pen.
Attention: Please use no pens or other objects with sharp edges!
The foil can be damaged!
11.1 Initialization
After switching on the LD 450, the
initialization takes place and then switch

If the calibration finished positive a message
“Calibration successful” appears and have to
be confirmed with OK.

11.3.5 Set backlight brightness
Home ➔Settings ➔Set backlight
Remark:
At the first touch, the Backlight in our example is reset to 39%, after that a "normal" function
operation is possible.
Important:
If the Backlight dimming after button is not activated, then the Backlight stays permanently
on, in the currently set brightness.
Here you adjust the desired Backlight
(15-100%) of the display directly.
E.g. Backlight to 39 %
With the help of the Backlight dimming after
button, after a definable time interval (here
after 15 minutes), the Backlight can be
reduced to the minimum.
As soon as the dimmed screen is operated
again, the Backlight is committed
automatically on the last set value before
dimming.
To reduce the energy consumption (device
runtime), you can switch off the display
backlight by setting "Backlight off after".

12 Charging the batteries
The battery is charged within the device. For this, the supplied plug-in power supply is connected to
the built-in charging socket of the LD 450 and the 230V socket.
The LD 450 checks the charging status of the battery and starts the charging process automatically if
necessary.
To protect the Li-ION accumulator of exhaustive discharge the device is switching off automatically if
a cell voltage of 6,4V will be reached.
Connect external power
supply to the charging socket.
Symbol „CHG“ is
displayed during
charging.
