Accurately measures AC/DC voltage, resistance, on-off test and NCV detection. This multimeter is a really useful tool for solving industrial and household electrical issues. Features: Versatile Digital Multimeter: Accurately measures AC/DC voltage, resistance, on-off test, NCV detection. Non-Contact Voltage Detection (NCV): Place probe close to electric sockets, outlets and terminals to test voltage and live wires safely. Data Hold: If you want to record the measurement value, just press the 'HOLD' button, then the reading showed on the screen will be locked. Strong Backlight and Flashlight: The flashlight acts a torch and the backlight perfectly illuminates the LCD screen so you can work perfectly in the dark. Automatic Shutdown: The instrument will automatically cut off the power supply for about 15 minutes of no-use to save energy.
