3. Electrical Discharge
Electrical discharge associated with insulation breakdown, tracking, corona, and arcing.
4. Mechanical Wear
Condition of mechanical wear in bearings, valves and race assemblies, shafts, gears and etc. Also accurate
indication of proper lubrication in anti-friction bearings.
5. Sound Generation
The Receiver can be used in conjunction with Tone Generator to detect container cracks and seals, door seals
and compartments.
INSTRUCTIONS
Receiver
The Receiver incorporates audio feedback
and a 10 bar LED indicator for visual intensity
of signal.
It has a permanently xed 33mm directional
receiver port, 3.5mm stereo jack and a rotary
on/off volume control switch. It is powered
by a 9V battery.
The LED display allows the user to zero in
on a steady state source of ultrasonic sound
when locating a gaseous or vacuum leak
or using the Tone Generator. The ultrasonic
intensity indicated on the LED display will
increase when you get closer to the location
of the leak/noise source.
Simply use the method described in Step 5 of
the Basic Operational Procedure section to
test the performance of the Receiver.
If no sound is heard, replace the battery.
Probes
Both the air and contact probes are precision parts, designed to optimize the response of the Receiver when
needed. The 30cm air probe serves to extend reach or to facilitate isolating a leak among multiple suspect areas.
Before you connect the air or contact probe to the Receiver, you must rotate the bolt of the Receiver anticlockwise to
back it. Insert the connecting end of the probe into the receiver port of the Receiver, then rotate the bolt clockwise
to x the probe (refer to the following gure).
Note: Do not modify the probes in any way and never use the probes for unintended purposes.
