Guest Tip by Bob Dunn from I&E Central, Inc.

In some environments, reflected sounds can make it difficult to locate a leak.  If you are in a confined area (a smaller room, or beneath/inside a machine), the leak can seem to be almost anywhere.  A good solution is to adjust the sensitivity downward.  Ultrasonic sounds will reflect, but lose energy each time they reflect.  By reducing sensitivity, the reflected sounds drop into the background, allowing you to locate the actual source of the leak.

Note that SDT inspection tools have separate adjustments for sensitivity and headphone volume, so you can manage sensitivity without affecting your ability to hear!
