Feature: 1. It is suitable for many scenes, such as introduction to electronics beginners, electrical installation of home improvement lines, electronic product maintenance, factory electromechanical maintenance and testing, etc. 2. Smart recognition is simple and easy to use, voltage detection, long press the power button to turn on. The test lead touches the neutral wire and live wire, and the screen immediately displays the voltage value. 3. There is an NCV test point at the front end of the meter. As long as the point is close to the AC voltage, the buzzer will emit an uninterrupted sound according to the different strength of the signal. At the same time, the analog bar will also display different signals according to the strength of the signal. Number of segments. 4. Insert the tip of the red test lead into the neutral or live wire. If it is a live wire, the buzzer will emit a continuous beep, at the same time the panel indicator flashes, and the screen simulation bar shows full grid. If it is the live line, the meter will beep intermittently and the analog bar on the screen will display half or one grid. 5. With flashlight function, it is convenient to measure in the dark or dim environment, which is very practical.
