waste. This product needs to be RECYCLED in accordance with local regulations,
contact your local authorities for more information. This product may be returnable to
your distributor for recycling - contact the distributor for details.
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 associated with a pressure leak or an
electrical corona. The contact probe is best used to detect the ultrasounds generated from within
a casing such as in a gear, bearing, pump, solenoid, valve, or steam trap housing.
Specific Applications
For air/gas and electrical leaks - Use receiver with black air probe for better pinpointing of leaks.
A leak is very directional and sounds like a rushing sound. Scan side to side as you walk toward the
increasing sound (suspected leak). You should decrease volume as the sound increases to reduce
fatigue.
For analyzing internal sounds - such as for mechanical bearings, gears, rotors, or turbulence in
pneumatics, steam valves, and solenoids or electrical discharge like in top over coils. Attach the
contact probe making sure it is seated in the nose of the receiver with the thumbscrew firmly screwed
down. Hold tip of probe to appropriate areas while equipment is running. For a wheel bearing,
safely jack car and touch stationary hub while turning wheel by hand.
For analyzing non-pressurized vessels - such as for windshield/door leak. Turn Tone Generator
on and position in vehicle with nose pointing toward suspect area. Close all openings such as doors,
windows, etc. and walk around exterior with the receiver. Listen for increased and decreased sounds
from the Tone Generator leaking through cracks and voids in gaskets, etc.
