1. Live zero and live wire judgment and wiring detection: In Live mode, zero and live wire are distinguished, and the installation wiring is clear at a glance. The live wire alarms, and the zero wire has no response.2. The large flip screen can be adapted to the situation: 180 adjustment of the appropriate angle measurement, convenient to carry and place at work.3. NCV non-contact voltage detection: Switch to the NCV function to display EF. When the AC voltage is detected by the NCV sensing part at the bottom left of the meter, the meter emit a buzzer alarm and the LCD simulation bar display the sensing intensity.4. USB lithium battery direct charging plug and play: built-in 3.7V/1800mAh lithium battery, connecting Type-CUSB lithium battery direct charging is convenient and fast.5. Wide range of application scenarios: multi-scenario use, engineering operations, mechanical maintenance can be easily handled.
