has a leak rate of approximately
0.5 oz/year.
MEDIUM switch position is used for
chlorine-based (CFC and HCFC) gases like
R12 and R22. The medium setting will
indicate approximately a 0.1 oz/yr (or
greater) leak rate. This position supports
finding leaks of approximately 0.5 oz/yr
(per SAE J2791) or greater. It is also
useful for locating larger HFC leaks.
When using the medium leak range
position on a CFC or HCFC system, this
leak rate would also be approximately
0.5 oz/year.
LARGE switch position is used to zero in
on large leaks of any refrigerant. The
large leak setting should be used in
conjunction with manual mode.
2.5. Auto Mode vs. Manual Mode
Auto mode enables the H-10 Pro to block
out background levels of refrigerants. This
greatly reduces and/or eliminates false
alarms while retaining sensitivity to
quickly locate small or medium size leaks.
Pinpointing leaks in this mode requires
continuous probe movement.
If the probe is held stationary over a leak,
the unit will zero out the leak, going into
the idle 1 tick/second condition. Briefly
moving the probe away from the leak (1-2
seconds) permits the unit to re-establish
sensitivity. Returning to the leak site, the
unit will alarm again. Continuing this
