Increasing and Decreasing the Sensitivity
To increase the audibility of the sound of a small leak, or in the opposite case, to decrease
it when the sound of a leak is too loud, adjust the sensitivity to the desired level using the
[
×
] and [
Ø
] buttons.
1) Pressing the [
×
] button one time increases the
sensitivity setting by 1. Holding down the [
×
]
button rapidly increases the setting (in single
increments) until the button is released. The
level can increase to a maximum of 100.
2) Pressing the [
Ø
] button one time decreases the
sensitivity setting by 1. Holding down the [
Ø
]
button rapidly decreases the setting (in single
decrements) until the button is released. The
level can decrease to a minimum of 0.
7.5
Using the Automatic Sensitivity Adjustment
It is possible to automatically set the sensitivity to an easy-to-hear level without the use of
the [
×
] and [
Ø
] buttons.
1) Pull and hold the trigger for at least 1 second.
2) The sensitivity setting is automatically altered
until the current reading reaches a level that is
easy to hear.
3) When the trigger is released, the setting
becomes fixed at the last automatically assigned
sensitivity setting.
7.6
Turning the Laser Pointer ON and OFF
The laser pointer assists in identifying the location of a detected leak.
1) Pressing and holding the [
] button causes the laser pointer to emit a laser beam,
and a “
À
” mark appears in the display.
Note: The laser pointer only emits a laser beam while in
detection mode. When modifying settings, saving
data, recalling data, etc., it does not emit a beam.
2) When the [
] button is released, the laser pointer beam
is turned OFF and the “
À
” mark disappears from the
display.
