The voltage detector probe is placed near the AC voltage. When the voltage is induced, the signal light will be lit. The bargraph of the screen will become higher or lower as the voltage signal intensity is induced, and the beep beep hint will become faster or slower with the signal intensity.
Note 1: because the socket structure is different, when not by the backlight color change to distinguish the Live and neutral, generally according to the detected signal intensity to distinguish.
Note 2: Distinguish Live and neutral, ifLive and neutral is near, the two lines can be separated as far as possible; it is true that it is not separable and can be distinguished according to the intensity of the signal. One of the
