Ultrasonic Diagnostic Tool

USING AIR OR CONTACT PROBES
The air and contact probes are used to optimize the response depending on the type of inspection. The air probe is best used for detecting ultrasounds assciated with a pressure leak or an electrical corona. The contact probe is best used to detect the ultrasounds generated from within a castingsuch as in a gear, bearing, pump, solinoid, valve, or steam trap housing.


USING LED GRAPH ON RECEIVER AND/OR HEADPHONES

Depending on the amount of ultrasonice signature being etected, use either the level of intensity on the LED graph and/or the audible amount of sound through the headphones. As you get closer to the problem decrease the volume. As the sound gets louder, repeat the process until you have pinpointed the location. Please note that the volume control is independent of the bar graph intensity during an inspection. With minute leaks, the LED bar graph may ot move up from the first position. In this situation, use the audible signal as discussed above.
