1. horn is identified by a single groove in the horn body and the large aperture at the end of the horn Signals wider than 30 can be detected but their intensity is reduced Their source is easily identifiable by the audio feedback the user has 3 horn For very accurate location of the leak source the 3 horn can be used This gives a very narrow beam of acceptance of signal and thus pin points the source of the leak It is not a good idea to start general leak surveys with this horn attached The 3 horn is identified by two grooves in the horn body and a small aperture at the end of the horn Bending horn The bending horn is for detecting leaks in difficult to access places such as boxed in pipework or in clusters of pipes The flexible pipe allows it to be threaded into hard to gain locations and essentially allows the detector to listen around corners Spare parts If any items are damaged or lost then they can be obtained separately from your agent A list of parts and their part numbers is included below P311 010 010 30 horn P311 010 020 3 horn P311 010 030 Bending horn P311 050 100 Battery charger P311 050 200 Earphones J311 ULTRASCAN LeakDetector UserManual 1 01 doc Designed and manufactured in the UK by E2L Limited Copyright 2004 Right to change product specifications reserved www ed2l uk com2.

4. ne the surrounding environmental noise is quieter and it is much easier to discern the signal coming from a gas leak By demodulating the ultrasonic noise we can make the signal audible to the human ear Consequently a leak sounds like a rush of air just as you would expect but without all the other audible surrounding noises included The same principle applies to vacuum systems and corona or plasma discharge By effectively detecting leaks results in 1 The cost of generating the compressed air vacuum or steam can be optimised not wasted 2 The workplace becomes safer J311 ULTRASCAN LeakDetector UserManual 1 01 doc Introduction Welcome to your ULTRASCAN leak detector We have made the ULTRASCAN simple to use but please read this manual to familiarise yourself with all of the operations and especially the safety instructions ULTRASCAN is a rechargeable battery powered portable unit intended for investigative tests lasting up to 18 hours As with any machine the care that you give it will reflect on its operational life and reliability Please take note of any safety and care instructions in this manual Because of the sophisticated design of the ULTRASCAN none of the internal parts are user serviceable Only have your instrument serviced or repaired by a approved E2L agent who has access to the correct equipment and spares In each section we guide you through the investigation process with examples plus other informat
