The ULD-400 comes supplied with additional Receiver accessories that are helpful in
leak identification. Plug the headphones into the Receiver to audibly hear the leak and
verify its source (for example hissing sound of an air leak versus ticking sound of an
electric discharge). Use the Parabola attachment in situations where there is a high level
of background noise to help direct the ultrasound towards the sensor. Use the Tubular
Extension with the Adapter in hard to reach areas for additional reach.
Note: There is no speaker on the Receiver. Without headphones, no noise will be audible.
