1. Pen type design, the small size of this tool is convenient for everyday use, you can put it in your pocket to carry. 2. 1.9 Inch Bicolor Screen: The three results display modes makes it easy to the detected strength, the white means null, the green means low and the red means high. 3. True function is to accurately measure non-sine waves power, when measuring AC current and , the true function is also important. In low light or dark environments, you can turn on the flashlight to help you better detection. 4. Multifunctional Multimeter: This multimeter supports measuring, capacitance and resistance measuring, diode and frequency measuring, continunity and room temerature measuring. 5. This tool can be widely used in your home daily maintenance, car repairs, electricians, mechanical repairs, etc. The breakpoint location function can help you to locate the breakpoint according to change of detected strength.
