Foreword
LD500 V1.00 Seite 4von 68
2Foreword
Dear Customer,
thank you for purchasing our leak meter with camera LD 500.
The new leak meter LD 500 with integrated camera and leakage calculation are ideal measuring
instruments which help to find and document even smallest leakages (0.1 l/min corresponds to approx.
1 € p. a.) easily even in far distances.
The LD 510 is the worldwide first leak meter with an additional freely assignable sensor input for all CS
sensors. In addition to the leakage measurement and detection also all necessary measurements with
regards to dew point, flow, pressure, and temperature ... can be carried out
Main functions:
Tracking and location of leaks
compressed air, gas, steam and vacuum systems
condensate drain
seals
refrigeration systems
Documentation / storage of leaks with
Image of the leak position
Date / Time
Description of the leakage position with indication of company / department or hall /
machine
Size of the leak in liters / min (units adjustable)
Leakage costs per year in € (currency freely definable)
Remark: By means of the additional available CS leak Reporter (Order No .: 0554 0105)
detailed reports with summary totals, subtotals (departments / warehouses etc))
as well as history reports (for temporal / continuous improvements) could be created.

General function description
LD500 V1.00 Seite 6von 68
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 LD 500 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 LD500 device calculates the costs 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 LD500 finds typical application in leak detection in compressed
air systems and leak testing of pressure less systems.
With the help of an integrated laser pointer, which serves as a targeting, the leak can be pinpointed.
Depending on the leakage, the appropriate accessories may be used to increase the sensitivity of the
LD500 to use, available accessories are:
Acoustic trumpet
Focus tube with focus tip
Gooseneck
Parabolic mirrorarabol

6.6 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.
Picture 7
6.7 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.

9.1 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 for smallest leakages starting from 0.1 l/min
10 –70dB
20 –80dB
30 –90dB for bigger leakages up to max. 50 l/min
Remark: In case of high noise level to switch to next lower sensitivity level.
These steps can be selected manually by pressing the „ Sensitivity“button.Levels are changed to the
next level each time they are pressed.
The„Auto“ setting allows you to automatically switch to the preferred sensitivity level for the
LD 500. However, this requires a min. measuring time of 2 seconds.
Auto(1) correspond to 0–60dB , Auto (2) to 10-70dB, Auto(3) to 20-80dB and Auto(4) to 30-90dB.
9.2 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! V Avoid direct / indirect (via reflexion)
irradiation of the eyes in humans and animals!

9.3 Parameters for measurement
To get correct readings, the parameters
• Existing pressure
• Distance to measuring point
are needed. By pressing the key „Parameter“ in the display, the parameter input window is
opened.
Note: Distance refers to distance from measuring point to acoustic trumpet or
focus tube with focus tip.
Appropriate input range is 1m to 6m for acoustic trumpet , for focus tube with focus tip fixed
to 20cm.
Pressure input range is 0.3bar to max. 10bar, for vacuum leakages -0.1bar to -1bar.
The pressure entry can be made by selecting one
of the 3 predefined values or via the text field.
Max. Permissible pressure value is 10bar.
In case of higher pressures, please insert 10bar)
For the distance input, there are 4 predefined
values or a text field for the measurement-
specific distance entry.
Selection „20cm“ is reserved for the
measurement with the focus tube with focus tip.
Currently the max. Measuring distance is 6.00 m.

9.4 Storing oft he measurement
To store the measurements please press either the button „Store“on the foil keypad, see chapter
Device components and controls , or by button „Store“in the display.
All data are stored on to the inetrnal SD card.
After pressing one of the two „Store“keys, the corresponding information for the measuring point must
be completed. The measuring point information of the last stored storage (company, building and
location) is displayed, the numbering of the leaking day is increased by 1.
e.g .:
If necessary, fill out the
LeakTag-form and attach it to
the measuring location.
Please use correct LeakTag-
number.

9.4.2 Parameter of measurement (Re-Check)
Store  Parameter
At this point, it is again possible to check and correct the parameters „Pressure" and „Distance".
Changing the parameters gives new values for leakage and cost.
Execution of the corrections see description chapter 9.3
All information about the measuring point can
be changed by selecting the corresponding text
field or the stored measuring points can be
loaded from the internal database.
Then a menu opens with the available / saved
entries.
When selecting a saved value, select it
(highlighted in green) and then take over with
„OK“.
If a new entry is necessary, the input menu
opens after pressing the „new“ button.
Input is accepted via „OK“.
This procedure is analogous to enter the
information for company, building and location.
Using the „delete“ button, individual entries can
be deleted too.

with company, building and location, it is
possible to enter a comment (up to 32
characters).
To do this, select the text field „Comment“ and
enter the comment.
Before final storage of the measurement on the
internal SD card, a summary is created and the
correctness is queried once more for safety.
Storage is done with the „Yes“key.
The „No“key returns to the previous menu.
