Functional features:
1. Multi-function electricity test pen, bright color lights, strong torque measurement, insulated shell, drop-proof and durable, safe identification, fast and accurate
2. Electrician grade dual-use electrical pen, intelligent upgraded motherboard chip, higher security performance, longer life
3. Electrical pen/screwdriver two-in-one, insulated and drop-proof, with a strong magnetic tip, voltage sensing, zero fire line identification, line breakpoints to find
4. Bright sensitive color lights, security power measurement more eye-catching, fast detection, for a variety of electrical circuits hold down the nut, red and green at the same time light for the fire line only light green for the zero line
5. Self-test function, to ensure that nothing is wrong, through the human body circuit, will emit a bright light before using the self-test, whether the pen is in normal use does not light up means that the damage or need to replace the batteries
6. Line break detection, rapid detection of line failure, hold down one end of the pen with your hand to detect, the other end of the green light for the line is smooth, not light for the line breaks
7. DC power detection, battery polarity discrimination, a hand holding the pen with the tip of the pen to contact the battery positive pole, the other hand touching the negative pole, the light indicates that the power is sufficient, the light does not indicate that the power is insufficient or no electricity
