Function introduction:

1. Identifying the live wire: Place the pencil drill into the socket; if the green light shows, there is a wire present. If there's no light with another socket, it indicates a zero line. 2. Bright indicators: The high brightness feature facilitates easier measurements and remains visible even in direct sunlight. 3. Smart chip: The main board has a professionally upgraded chip for program control, ensuring enhanced safety and extended lifespan.

4. Detecting electrical switches: when the electric pen touches the contact rod, if the wire's inner core is intact, the green LED will illuminate; if it does not light up, the inner core has a poor connection. 5. Judging line break points: by testing along the line, if the green LED is on, the line is intact; if it is off, the line is broken. 6. Portable design: the pen's design makes it easy to carry while working, with thoughtful and meticulous features.

This can be utilized in electronics manufacturing, appliance repair, car maintenance, and various household applications, making it quite versatile.
