1. Pen type design, the small size of this tool is very convenient for everyday use, you can easily put it in your pocket to carry.2. 1.9 Inch Bicolor Screen: The three results display modes makes it easy for you to judge the detected voltage strength, the white means null, the green means low and the red means high.3. True function is to accurately measure non-sine waves , when measuring AC current and voltage, the true function is also very important. In low light or dark environments, you can turn on the flashlight to help you perform better detection.4. Multifunctional Multimeter: This multimeter supports voltage 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 voltage strength.Max Display: 4000 countsDisplay Type: Red/green bicolor screenScreen: 1.9 inchDirect current voltage: 0.05V-600V (0.8%+3); Resolution: 0.001VAC Voltage: 0.8V-600V (0.8%+3); Resolution: 0.001VResistance: 0-10M (1.2%+3), 10M-40M (2.0%+10); Resolution: 0.1Capacitance: 1nF-1.00mF (3.5%+8), 1mF-40.00mF (4.5%+10); Resolution: 0.001nFFrequency: 0Hz-4MHz (2.0%+10) (ACV: 3V-600V); Resolution: 0.1HzDiode: Auto identify diode if less than 1.5VV-Alert(non-contact voltage detection): alarm beep sounds, LCD screen display stripeContinuity: If the resistance is less than 50, the sounds: 2 x 1.5V AAA battery (NOT INCLUDED)Type: Bcolor:BlackMaterial:ABSPackage Contents:1 x Multimeter1 Pair x Test Pen1 x English ManualOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
