you can increase the volume as long as the leackage signal can be
determined.
Depending on the operating purpose the probe has to be connected to
the
SONAPHONE
RD
(
see section
"Application of the probes
“).
An air
sound probe is normally used for leak detection
.
The intensity of the
ultrasonic level depends on the dimension of the sound source, the
sound source orientation and the distance between the probe and the
sound source. So this effect can be used to detect and assess
leakages.
For leak detection, especially when a high surrounding noise level
occurs, the use of the sound deadening headphone is recommended.
For this reason the headphone has to be connected to the plug (Look to
the picture on previous page).
The volume can be controlled through the VOLUME knob, where the
position influences the intensity of the LED-scale.
Pressing the MAX button the storage of the maximum value of
ultrasound signals can be turned on or off. This function allows the user
to search for the maximum of the ultrasound source. When this function
is active, the yellow LED is lightened.
When the surrounding light is not sufficient, the display screen lights on
automatically.
