2.3. Before First Use…
Before you use the unit the first time:
1. Remove the sticky-label disc from the
cap of the calibration reference bottle.
This disc can be reused to help seal
the vial when the leak detector is not
in use, or it can be discarded. DO NOT
attempt to unscrew the cap, you may
damage the bottle. The calibration
reference bottle should last
approximately six months.
2. With the Power switch in the OFF
position, charge the battery using the
wall adapter. Charge time is 3-4 hours
or until the Full Charge LED turns
green.
2.4. Adjusting the Sensitivity
Set the Leak Size switch as follows.
SMALL switch position is the highest
sensitivity. The unit will indicate leak
rates of 0.006 oz/yr or greater and is used
for fluorine-based (HFC) gases like R134a.
This position also assures highest
repeatability for locating 0.1 oz/yr (or
greater) leaks per SAE J2791 moving
probe test conditions. It must always be
used to verify performance and
calibration when using the calibration
reference bottle.
When using the small leak range position,
a leak of HFC causing an audible signal
equal to that produced by the leak vial
