How To Find Leaks
NOTE: A sudden whipping of the leak detector probe or "blowing" 
into the sensor tip will affect the air flow over the sensor and 
cause the instrument to alarm.
1. Place the tip of the leak-detector probe as close as possible to 
the site of the suspected leak. Try to position the probe within 1/4 
inch (5 mm) of the possible leak source.
2. Slowly (approximately 1 to 2 inches/second (25 to 50 
mm/second)) move the probe past each possible leakage point.
