1、NCV Voltage Sensing: Use a multimeter to sense the top NCV position. When AC voltage is detected, the screen will display and sound an alarm, and the closer the distance, the more urgent the alarm will be. 2、Zero Wire and Live Wire Detection: In Live mode, a single probe is inserted into the socket for detection. Live wire: The screen turns red and emits a fast beep sound; Zero line: Live screen display shows no response. 3、The design of a two handed flashlight illuminates the front for you, turns on the screen lights, and even in dark environments, you can clearly see the screen values, making it easy to read. 4、Intelligent Fuse Protection: Equipped with a built-in fuse and intelligent anti burn protection, it effectively prevents short circuits and is not afraid of damaging the instrument, making measurement more secure. 5、Silicone Protective Sleeve: The silicone protective shell prevents falling, and the genuine material protects the body, effectively preventing falling.
