Features: Multi-Function: Phase detection (normal phase, reverse phase), live line inspection, simple electricity inspection, phase loss judgment, motor steering detection, circuit breaker search, breakpoint location, and line maintenance. LED dynamic display, intuitive and clear. Easy to read. The phase sequence table of the three exposed clips or test pins are connected to the exposed three fire lines. Measure mode: Non-contact clipping method. It does not need to open the wire, and does not need to touch the high voltage exposed live wire. It can directly detect the phase sequence by sandwiching the three super induction high-insulation clamps to clamp the three-phase live wire insulation sheath.
