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.
