Mode and Sensitivity Selection:
The Leak-Seeker
®
I
offers two modes of opertion. The Progressive
Alarm Mode should be used to guide the user to the source leak; the
pitch of the alarm and the number of LED's increases progressively
as the leak source is approached. The Progressive Alarm allows
searching for a broad range of leak sizes, and the searching should
be started in the large leak setting (L) since those leaks need to be
fixed first. If you start in the highest sensitivity setting, the alarm
may saturate far away from the actual leak and then you would
have to back to a lower sensitivity setting.
The Threshold Alarm Mode provides a quick go or no go mode
to verify that a leak has been found and its approximate size.
Always scan the suspected leak site several times to make sure
you are detecting a leak and not accumulated refrigerant.
Low battery indicator
:
When the batteries reach approximately 10% of capacity, the
GREEN LED turns OFF.
Windy conditions:
Locating leaks under windy conditions may severely impede the
leak searching process. Even very large leaks may be difficult to
locate as the escaping gas is quickly dissipated into the atmo-
sphere. If necessary, fabricate a gas trap using aluminum foil
around joints or fittings or otherwise shield the search area from
the wind.
Leak verification:
If a suspected leak is indicated, verify several times by moving
the sensor away from the leak area, resetting the unit and then
back to the suspected leak. If the instrument indicates a leak
three consecutive times, then you have found a leak.
