Quick Start Guide
Option 2 ... Walking along the compressed air system.
Alternatively, if there is more noise, you can make it easier to pinpoint the leak by "moving along
and listening to the compressed air system bit by bit." That is, from the compressor room all
the way to the end points. If there is noise, it is recommended to manually reduce the device's
sensitivity and use either the gooseneck for short distances or the parabolic mirror for long
distances.
In addition, the following generally applies when using this method: The shorter the distance from
the line, the easier it will be to pinpoint the leak.
Option 3 ... Searching for leaks while production is stopped
Production processes can result in ultrasonic noise in certain cases. If, for example, a pneumatic
system blows off air on a regular basis, the METPOINT
If noise makes pinpointing leaks significantly harder, it is recommended to use option 1 or option
2 if the lines are pressurized but the corresponding production processes are stopped. This is the
easiest and fastest way to find leaks.
9.6 Other problems that can make the measurement more difficult
CID will detect the corresponding noise.

When pinpointing leaks, there can be additional problems,
which are described in the following subsection. In order to
reduce these problems, the most important things to do are
to use the correct attachment as instructed in section 9.4
("Choosing accessories") and to reduce the sensitivity level.
Reflections: If you can hear leaks on walls but there are no
lines running along them, the sound is coming from reflected
ultrasound from a leak. In this case, it is recommended to
reduce the sensitivity (manually switch to a higher range until
you cannot hear the reflected sound anymore). In addition,
keep scanning parallel to the reflection area, as that is where
the leak is coming from (the leak will be louder than the
reflected ultrasound).
