1. Live zero and live wire judgment and wiring detection: In Live mode, the line 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 will emit a buzzer alarm and the LCD simulation bar will 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. Automatically select the measurement range Full range overload protection The maximum allowable voltage between the measuring end and the ground is 1000V DC or 750V AC Working altitude: up to 2000m Display: LCD Maximum display value: 19999 digits Polarity indication: automatic indication, "-" indicates negative polarity. Overrange display: "OL" or "-OL" Sampling time is about: 2 times per second Unit display: with function, display power unit Automatic shutdown time: about 15 minutes Power supply: 3.7V/1800mAh lithium battery Interface: Type-C Temperature coefficient:less than 0.1 times accuracy/℃ Working temperature:0℃-40℃ Storage temperature:-20℃-60℃ Tips:The product may be updated constantly ,Due To Different Batches, The Actual Product May Have Slight Differences Or Color Differences, Which Does Not Affect Use.
