 AC  5028 

 ELECTRONIC STETHOSCOPE LEAK DETECTOR 

Tone Generator

The Tone Generator emits a warble output centered at 40kHz for use in testing seal integrity in non-pressurized 

vessels. The human ear cannot hear this output, so the Tone Generator must be used in conjunction with the Receiver.

The Tone Generator is powered by a 9V battery. If the green indicator (LED) on the Tone Generator is on, the unit is

emitting ultrasound. Verify the Tone Generator's operation with the Receiver.

Receiver and Tone Generator Guidelines

1. Avoid handling Receiver or Tone Generator roughly.

2. The carrying case should be used for protection and transportation whenever possible.

3. The port openings of Receiver and Tone Generator contain the heart of the tool's operation, a precision 

transducer/ transmitter. During use, guard against any foreign substance or liquid from entering these areas.

4. The Receiver and Tone Generator are not waterproof and should be protected from any liquid.

5. To save battery power, make sure each unit is turned off when not in use.

Safety Precautions

Although this tool allows you to concentrate on diagnosing a problem in a fast and effective way, never lose 

awareness of your surroundings.

1. Keep a safe distance from moving parts and electrical areas.

2. Never over reach or de-stabilize your footing while using this tool.

3. To avoid personal injury, be wary of nearby moving object(s) while wearing the headphone.

4. Do not use the air or contact probe as a lever, pry bar, or for other unintended applications.

5. Do not use the contact probe to diagnose electrical problems or touch it to any live conductor.

Basic Operation Procedure

1. Insert the plug of the headphone into the jack on the front face of the Receiver.

Note: Do not wear the headphone before you turn on the Receiver.

2. Select the air or contact probe as needed (see the Using Air or Contact Probe section).

3. Turn the rotary knob forwards to turn on the Receiver, it will sound a click. Watch for the LED bar to settle to the 

bottom position.

4. Wear the headphone and adjust its volume with the rotary knob until you can just hear the background noise 

(hiss).

Please note that increasing the volume does not increase the Receiver's detection sensitivity. Setting the volume too

high can lead to operator fatigue.

5. When using the air probe, point the probe in the direction of your free hand while lightly rubbing your forefi nger 

and thumb together about 60cm away. The response should be the sound of sandpaper on wood. You can vary 

the distance and increase/decrease the level of volume accordingly.

While performing this test, familiarize yourself with the directional sensitivity of the probe while sweeping the

probe past your fi ngers at various distances.

6. When using the contact probe, adjust the volume to an appropriate level while lightly rubbing your fi nger along 

the tip of the probe rod.

7. The tone generator is used with the ultrasound receiver to check for faulty seals in nonpressurized enclosures, 

such as automotive cabin windows/doors/roofs, etc. Turn on the ultrasound tone generator and place it in the
