2.0 Battery Charging

The leak detector should be fully charged prior to use. Only use the AC adaptor or USB cable, both of which
are provided with the unit. To charge the battery using the AC adaptor, first install the correct plug for your
country's AC outlets onto the provided AC adaptor. Insert the AC adaptor into an electrical outlet, and then
insert the barrel plug on the other end of the AC adaptor into the connector on the bottom of the leak detector
unit. To charge the battery using the USB cable, simply plug the USB cable into the unit and into a USB port.
While charging, the green battery charge indicator LED will illuminate. When the battery is fully charged, the
green battery charge indicator LED will no longer be illuminated.
When the leak detector's charge is low, the blue LED located between the red and yellow LEDs will begin to
flash. It is important to charge the leak detector when the blue light is flashing to avoid complete battery
discharge and possible damage to the battery.
NOTE: If the battery is fully discharged, no LED will illuminate.
CAUTION: For the health of the battery, it is not recommended to continuously operate the leak detector
when it is plugged in and charging. However, if your battery has been allowed to fully discharge and will no
longer hold a charge, the unit can be operated while plugged in receiving charge directly from the power
supply. To operate the leak detector while it is plugged in, follow the instructions for regular operation, and
when the blue LED illuminates steady or flashing the unit is ready to use.
CAUTION: The leak detector contains a nickel-metal hydride (NiMH) battery. Like other battery-operated
devices, if the battery is left for long periods of time without being charged, it can discharge to a point where
the battery cannot accept a charge. We recommend that you charge the battery at least once every 3
months. If your leak detector is used often for routine maintenance, as recommended, more frequent
charging may be necessary.
CAUTION: Replacement of the rechargeable battery in this unit is performed at the factory. There are no ser-
viceable parts inside this unit. Opening the case or tampering with the internal parts will void the factory
warranty.
NOTE: Recharging a low battery can take approximately 6 hours.
NOTE: The leak detector may get warm to the touch during charging, but this is normal and not a safety
concern.

3.0 Powering Up

Remove the probe assembly from the holder. Depress and hold the power button (Figure 1) until the unit
responds by initiating a starting sequence that lasts approximately 15 seconds, during which the red and yel-
low LEDs will flash. When the red and yellow LEDs stop flashing and the blue LED illuminates, the unit is ready
to use or zero. During the starting sequence, DO NOT attempt to zero the unit.

4.0 Zeroing the Unit

The instrument may need to be zeroed periodically between uses, especially if it is moved from room to room
or between areas of differing temperature or humidity. Do not attempt to zero the unit while the probe is
stored in the holder. The probe MUST be removed from the probe holder (Figure 1) before zeroing the unit.
To re-zero, press the zero set button. The unit will run a re-zeroing sequence for approximately 4 seconds,
during which the red and yellow LEDs will flash. When all LED lights stop flashing and the blue LED light is lit,
the unit is ready for use.
NOTE: To avoid false readings, do not attempt to use or zero the unit while the zeroing sequence is in progress.
