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
Testo Sensor LD basic V1.01 EN Seite 9von 22
10 Start-up / / Application Testo Sensor LD basic
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 Testo Sensor LD basic 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 .
The sensitivity levels or the automatic function are selected via the "Sensitivity" button.
Sensitivity levels
0 –60 dB = Highest sensitivity level of the device (use with small leaks and no noise
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)
The LD basicoffers a manual selection as
well as an automatic function "Auto" for
setting the sensitivity.
Selection is made by pressing the
"Sensitivity" setting button.
When "Auto" is selected, the LD basic
selects the best possible sensitivity level.

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!

11.3.5 Set backlight brightness
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".
