10.6 Setting the Noise Limiter
(Factory default is “OFF”)
When it is turned ON, this feature is designed to protect the ear by cutting ONLY the
sound of sudden loud sounds when they are generated. It is different than an automatic
volume control in that the earphone volume is not throttled, thus
the volume of normal sounds does not become reduced. There
is also no effect on the leak detection reading. Use this feature
in combination with the noise level adjustment.
1) Press
[
×
] and [
Ø
] to switch between “ON” and “OFF”.
2) Press [ENT] to move the display to the next setting item.
3) Press [Func.] to return to detection mode.
10.7 Adjusting the Noise Level
(Factory default is “Maximum”)
This feature is used to set the cut level of the noise limiter. If the cut level is lowered too
much, the sound may break off. Use at a level at which the sound does not break off. As
there is no level indicator, perform the adjustment while monitoring the sound from the
earphones.
1) Pressing
the
[
×
] or [
Ø
] button one time adjusts the level one step. If the button is
pressed and held down, the level is continuously adjusted
until the button is released. To go from the minimum to the
maximum, the button must be held down continuously for
approximately 7 seconds.
2) Pressing the [
×
] button raises the cut level, and pressing
the [
Ø
] button lowers the cut level.
3) Press [ENT] to move the display to the next setting item.
4) Press [Func.] to return to detection mode.
10.8 Selecting Earphone Output Type
(Factory default is “Beat”)
The earphone output may be set to either “Burst” or “Beat”. “Beat” means that the
ultrasonic signal from the leak has been converted to an audible frequency, which is a
natural sound. “Burst” means that the intensity of the ultrasonic
signal from the leak has been converted to a pulsing signal that
allows the assessment of the size of the leak to be made based
on the speed of the pulse.
1) Press
[
×
] and [
Ø
]to switch between “Burst” and “Beat”.
2) Press [ENT] to move the display to the next setting item.
3) Press [Func.] to return to the detection mode.
