9. ify Leak Noise A harsh hissing sound or bird song NOTE To become familiar with the different sounds detected by the Tru Pointe Ultra listen to the sound of an air hose at low pressure or an aerosol cleaning spray then shake a set of keys This demonstration allows the user to distinguish between mechanical noise and leak noise 4 If there is leak noise in the area and the display is at 10 slowly reduce the sensi tivity until the display reads 0 NOTE The LED Bargraph Display is only for relative measurements If a scan of the system reveals an area with a reading of 2 and an area with a reading of 10 that can mean the detector is far from a leak or there are two leaks of differing sizes in the same area 5 Approach the suspected leak If the LED Bargraph Display reading increases reduce the sensitivity 6 When the general location of the suspected leak is determined adjust the sen sitivity to so that 4 5 lights are illuminated when the leak area is scanned This technique allows the user to accurately determine when the instrument is pointed at an area of increased ultrasound If the LED Bargraph display increases then the leak source is getting closer If the display decreases then the leak source is getting further away Tru Pointe Ultra Instruction 0028 9000 Operating Tips 1 If the test area is large remove the nose cone Without the nose cone the detec tion area of the Tru Pointe
