4) The gas sensitivity can be set from five levels in descending order of sensitivity 0,
1/5, 1, 2 and 3. Change the gas sensitivity as needed when using the Gas Leak
Detector.
Decreasing the Gas Sensitivity Level
Each time pressing the power button, the
buzzer will sound once and the gas sensitivity
level will be decreased one level. The lighted
gas sensitivity lamp (green) will move up one
by one, and the LCD will also display the same
sensitivity level as shown on the gas sensitivity
lamp.
When the gas sensitivity level is decreased
beyond 3, the level will return to level 0.
Increasing the Gas Sensitivity Level
Each time pressing the power button twice (like
double-click), the buzzer will sound twice and
the gas sensitivity level will be increased one
level. The lighted gas sensitivity lamp (green)
will move down one by one, and the LCD will
also display the same sensitivity level as shown
on the gas sensitivity lamp.
When the gas sensitivity level is increased
beyond 0, the level will return to level 3.
•
The detected gas concentrations for the gas sensitivity levels are as
follows.
Level 0: Detects concentration of 10 ppm or less.
(Detectable gas leakage: 3.3 × 10

/s)
Level 1/5: Detects concentrations of around 30 ppm.
•
The gas sensitivity level is always 1/5 for Freon gas and cannot be
changed.
