of 1” - 2” per second (25 - 50mm per second) and held 1/4” (5mm) away from the surface. An increase
in the alarm rate will indicate a leak. To confirm the correct leak location, blow shop air around the
suspected leak area, move the probe into fresh air, reset and reinspect.

these areas, allow the unit to adjust to the existing environment before inspecting. Pressing the
