Feature:1. Zero live wire determination: Hand touch cap test socket,the green light is the zero line, and the traffic light is the fire line.2. Voltage sensing:The green light will turn on when a voltage is sensed.3. Line breaking point judgment: Check along the wires, where the green light disappears is the breakpoint.4. Bright beads: High brightness operation makes measurement easier and still clearly visible in sunlight.5. Intelligent chip: The main board professional upgraded chip control program, higher security, longer service life.Specification:This set includes a flathead and a Phillips screwdriver, both equipped with a bright indicator light. Perfect for electricians and DIY enthusiasts, this screwdriver set can be used for testing, detecting breaks, and checking zero-fire connections.
