6. In most cases, it is not necessary to adjust the sensitivity of the instrument. However, if the
alarm sounds before a leak source can be found, it is likely the air is contaminated with
heavy concentrations of gas. You may desensitize the instrument by turning the sensitivity
knob counter-clockwise to a lower setting in order to pinpoint the leak location.
NOTE: Joint compounds used on newly installed piping may contain combustible solvents and
could cause a false alarm.
Status and Leak Intensity Indicators
Five (5) small LED status indicators are located on the right front of the instrument, in a vertical
column arrangement. Six (6) Leak Intensity indicators are arranged in a horizontal row, below
the status indicators and Sensitivity control knob.
From top to bottom, the Status LED display functions are:
Power (red): Illuminates when the instrument is ON.
Low Battery (red): Illuminates when a battery charge is
needed. The battery pack must be fully recharged before
the instrument is used again.
Charge (yellow): Illuminates during the recharge process.
Ready (green): Illuminates when the charge cycle is
complete. A fully charged battery pack provides up to three
(3) hours of continuous operation.
Fault (red): Illuminates only if there is a problem with
charging the battery pack.
Leak Intensity Indicators (red): Illuminate from left to right,
indicating stronger leak intensity as more LEDs are lit.
Cleaning and Maintenance
Do not allow dirt or grease to obstruct the charger input jack on the side of the instrument.
Use only a soft cloth dampened with mild soap to clean the body of the instrument.
Do not subject the instrument to extreme mechanical shock, exposure to strong magnetic
fields or extreme temperatures.
Do not drop the battery pack or subject it to mechanical shock or extreme temperatures.
Never immerse the instrument or the probe into a liquid.
