measurement
Each time the red record 'Take measurement' button is pressed, the leak noise acquired in the
previous three seconds is recorded and displayed as a vertical bar on a histogram. In the
example above, eleven consecutive readings have been taken by stepping the ground
microphone along the length of the pipe and pressing the sample button at each position. This
indicates the greatest leak noise acquired and the probable position of the leak.
