NOW . . .
YOU’RE READY TO FIND THE LEAK !
(You have a choice of two modes)
Auto Mode
This mode is preferred because the
unit effectively auto zeros to block out
background levels of refrigerants and
changes in background contamination.
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.
(We recommend 2 inches per second
as specified in SAE J1627 and J1628).
If the probe is held stationary over
the leak the unit will zero out the leak,
going into the idle 2-3 ticks/second con-
dition. Briefly moving the probe away
from the leak, for 1-2 seconds, per-
mits the unit to re-establish sensitivity.
Returning to the leak site, the unit will
alarm again. Continuing this procedure
will reliably and repeatedly pinpoint the
leak with each pass over the leak site.
If a large leak is present, the auto
zero circuit may reduce sensitivity to
an unacceptable level to find small and
medium sized leaks. If this condition
exists, the manual mode will enable you
to pinpoint the large leak.
WARNING:
Personal Injury Hazard
Do not use the H-10PM in an explosive
or combustible atmosphere. The ambient
atmosphere is drawn through the probe
and through the sensor, which operates at
approximately 1472°F (800°C). The
resulting hot mixture of air and combustible
gas could explode.
