The highest sensitivity level 0 60 dB of the unit can be set using the "HiSn" button or by manually
changing the sensitivity level using the "Sensitivity" button. This mode should be used for the detection
of small leaks in a quiet environment.
6.5.1 Sensitivity level button
You can manually switch between individual levels with the
"Sensitivity" button or use the auto function to adjust the level.
The order is shown in the chart on the left.
6.5.2 Auto function (default)
The auto function (automatic change of the sensitivity levels) is activated by default. This means that
the measured ultrasound level is used to automatically adjust the optimum measurement range.
Example: Level = 71 dB Level: 20 80 dB
6.5.3 Manual sensitivity adjustment
It is also possible to switch between sensitivity levels. This can be done with the "Sensitivity" button.
It helps the user to reduce interfering noise and detect leakages as easily and quickly as possible. The
user should frequently increase and decrease the sensitivity to scan the target surface for leakages
with the adjusted sensitivity. Decreasing the sensitivity makes the device react to a smaller area but
also reduces the range.
6.5.4 Procedure for leakage detection
Different approaches to leakage detection are
recommended depending on the ambient condi-
tions.
Option 1 In what direction can the leakage be
heard? This method is used to aim in all directions
and find the loudest point. The loudest point
should then be approached to precisely locate the
leakage. Works well when there is less interference
from noise.
