2Foreword
Dear Customer,
Thank you for purchasing our leak meter with camera Testo Sensor LD pro.
The new leak meter Testo Sensor LD pro with integrated camera and leakage calculation is an ideal
measuring instrument which helps to find and document even smallest leakages (0.1 l/min corresponds

Main functions:
Tracking and location of leaks
compressed air, gas, steam and vacuum systems
condensate drain
seals
refrigeration systems
Documentation / storage of leaks with
Picture of the leak position
Date / Time
Description of the leakage position with indication of company / department or hall /
machine

3Safety instructions
3.1 About this document
Read carefully this documentation and familiarize yourself with the product
before putting it to use. Pay particular attention to the safety warnings to prevent
injury and product damage.
Keep this documentation to hand for easy reference when needed.
Pass on this documentation to any subsequent users of the product.
3.2 Ensuring safety
Only use the product as intended and within the parameters specified in the
technical data. Do not use force for operating.
Never measure with the device at or near live/energized parts!
During leak detection on electrical systems, please maintain a sufficient safety
distance to avoid dangerous electric shocks!
Avoid any direct contact with hot and/or rotating parts.
Always switch on the device before putting on the headphones! At high signal
levels (bar graph headphones in the red area), the volume can be correspondingly
high. The sensitivity setting can be used to reduce the volume.
Never point the laser directly into eyes! Absolutely avoid a direct irradiation of
eyes of humans and animals!
Laser module: corresponds to DIN EN 60825-1: 2015-07 Class 2 (<1mW)
Observe the prescribed storage and operating temperatures.
Improper handling or violence will void the warranty.
Any kind of interventions on the device, as far as they do not correspond to the
intended and described procedures, lead to the warranty expiration and to the
disclaimer.
The device is intended solely for the described purpose.
A use in hazardous areas is not allowed.
3.3 Environmental protection
Disposal of faulty rechargeable batteries / empty batteries in accordance with applicable
legal regulations.
Lead back the product after the end of the period of use to the separate collection for
electric and electronic devices (observe local regulations) or return the product to Testo
Sensor GmbH for disposal.
Testo Sensor GmbH assumes no warranty as to its suitability for any particular purpose and assumes no
liability for any errors contained in this manual. Nor for consequential damages in connection with the
delivery, performance or use of this device.

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 ".
