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.<br><br>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.
