Title goes here.
*Voltage sensing, anti-drop insulation and no leakage: When the nearby AC voltage is detected, the green LED light in the middle lights up for non-contact electrical measurement to prevent electric shock hazards
*Smart motherboard chip: higher security performance and longer life
*Intelligent identification of neutral and live wires: when using, touch the top pen cap with your hands, neutral wire - the indicator light is green, live wire - the indicator light is red and green
*Slotted/cross bit: 4mm bit diameter, 25mm length, magnetic bit
*Line breakpoint search: detect along the line, the place where the LED green light is on is unobstructed and good, and the LED is not on for the line disconnection point
