 Keep children and unauthorised persons away from the work area.
 DO NOT disassemble the tester for any reason. The tester must only be checked by qualified service personnel.
 WARNING! To avoid damaging hearing, DO NOT set headphones volume too high.
 DO NOT drop the detector or transmitter.
 DO NOT tamper with the electronic circuit boards within the dectector or transmitter.
 DO NOT use the tester outdoors, or in damp, or wet locations and DO NOT use in the vicinity of flammable liquids or gases.
 DO NOT use the dectector or transmitter near any electrical appliances which emit electromagnetic waves, as this will give a false reading.
 DO NOT use the tester for a task for which it is not designed.
 When not in use, store the tester carefully in a safe, dry, childproof location.
 If the dectector and transmitter are not to be used for long periods, remove the batteries before storing.

3. OPERATION
WARNING! Ensure the headphone volume setting is set to low before operating the unit.

3.1. Operating in Passive Mode.
3.1.1. Insert the headphones plug into the jack (fig.1.7) and put on the headphones.
3.1.2. Press and hold down the TEST button (fig.1.6), the POWER LED will light (fig.1.4). A ticking tone will be heard through the
headphones, adjust the volume of the headphones to a suitable level (fig.4). Adjust the sensitivity control to eliminate external noise
(fig.2).
3.1.3. Holding down the TEST button, move the detector probe around the joint or seal of the suspected area. If a leak is detected the
ticking tone frequency will increase and the "LEAK" LED will also illuminate (fig.1.5). The closer to the leak the higher the frequency of
the ticking tone.
Note: When the PP4 detects a possible leak, move the probe around the suspected leak to determine whether the ultrasonic sound is from
the leak or from other areas. Keep the probe as close as possible to the test area and move the probe slowly.
3.1.4. Repair the leak and recheck with the detector.
3.1.5. Once testing is complete release the TEST button.
Note: There are many factors involved in the ultrasonic leak detection, such as the pressure within the vessel, the size and shape of the
hole, temperature etc. In some cases the ultrasonic sound caused by the leak may be very weak, so the sensitivity will need to be set
at the highest level. If the ultrasonic sound is too intense, the ticking tone frequency will be high, the sensitivity should be adjusted
down to an acceptable level. Noisy environments may also increase the ticking tone frequency, adjust the sensitivity down to an
acceptable level.
3.2. Operating in Active Mode
3.2.1. Switch on the transmitter (see fig.1.1 & fig.3), the "POWER" LED will illuminate (fig.1.3).
3.2.2. Place the transmitter inside the compartment to be checked and close the compartment. The ultrasonic sound generated by the
transmitter (fig.1.2) will leak though any orifice or faulty seal.
3.2.3. Scan the the outside of the compartment with the detector. Any leaks from the compartment can be easily detected and pinpointed.
3.2.4. When the check is completed remove and turn off the transmitter.
