General function description
Testo Sensor LD pro V2.00 Page 6of 48
4General function description
When gases escape from leaks in piping systems (leaking screw connections, corrosion, etc.), noises are
generated in the ultrasonic range. With the Testo Sensor LD pro even the smallest leaks, which are
inaudible to the human ear and not visible due to their size, can be located several meters away.
The inaudible ultrasound is converted to audible frequencies in addition to the display emission level
shown in the display. With the convenient, sound-proof headphones, these sounds can be heard even in
noisy environments.
In addition, the new Testo Sensor LD pro calculates the cost associated with leaks, providing additional
transparency about the state of the system under test or the potential cost savings.
The loss is displayed in l / min as well as in a freely selectable currency. The cost per liter or per cubic
meter of compressed air can be stored in the device.
The professional measuring instrument Testo Sensor LD pro finds typical application in leak detection in
compressed air systems.
With the help of an integrated laser pointer, which serves as a targeting device, the leak can be
pinpointed.
Depending on the leakage, the appropriate accessories may be used to increase the sensitivity of the
Testo Sensor LD pro, available accessories are:
Acoustic trumpet For general measurements (0.2 - 6m) in directly accessible areas
Focus tube with focus tip For punctual measurements in directly accessible areas
Gooseneck For punctual measurements in hard-to-reach areas
Parabolic mirror For leakage measurements (3m - 12m) at longer distances
Note: To use the parabolic mirror and gooseneck, these components must be activated 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 ".

7.7 Assembly with acoustic trumpet
The acoustic trumpet allows acoustic amplification by bundling the sound waves. Due to the special
design, the integrated laser pointer will work properly. The camera is integrated at 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 reverse order, for unlocking the preamplifier module, the release
button must be pressed too.

7.8 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 reverse order, for unlocking the preamplifier module, the release
button must be pressed too.

7.9 Assembly with Gosseneck
Due to its flexibility, the gooseneck tool is used for punctual measurements in hard-to-reach areas.
Connection to the Testo Sensor LD pro 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.
Picture 10
7.10 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 Testo Sensor LD pro 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.

10.4 Sensitivity settings
In order to cover a measuring range from the smallest leaks (0.1 l / min) up to large leaks,
the LD 500 has different measuring sensitivity levels:
0 60dB
10 70dB
20 80dB
30 90dB
40 100dB
Note: The measurement sensitivity level 0 -60dB (most sensitive setting) can only be used in manual
mode. The mode can be changed by pressing the "Mode Switch button".
HiSn -- manual sensitivity mode
Auto -- automatic sensitivity mode
The individual stages can be selected in manual mode by pressing the "Sensitivity" setting button. The
steps are changed to the next step each time the button is pressed.
The„Auto“ setting allows you to automatically switch to the preferred sensitivity level
for the Testo Sensor LD pro. However, this requires a min. measuring time of 2 seconds.
10.5 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.
Please note the warnings for laser operation!
Avoid direct / indirect (via reflexion) irradiation of the eyes in humans and animals!
