During the mobile sweep, the sensor detects the leak signals and converts them into audio signals audible to the human ear, which are simultaneously displayed on the screen. On the LCD screen, the source of the leak is a real-time visible image in yellow (smaller leaks, weaker signals) or red (larger leaks, stronger signals). At the same time, the RMS and maximum values of the continuous sound decibels are displayed in different colors and values in the horizontal bar light column at the bottom of the LCD screen.
