Features Improve Measurement Efficiency: The intelligent identification technology enables the multimeter to automatically identify the measured parameters and select the required range, which greatly improves your measurement efficiency. LCD Screen: Three test results can be displayed on the color LCD screen, namely voltage, frequency and analog bars. Easy to Read: The multimeter's screen background color is black, which provides a clear contrast to the colorful numbers and letters, making it very easy to read. Smart Standby: When there is no signal input for about 10 seconds, the multimeter will automatically reduce the screen brightness and increase the battery life. Stable Performance: The charging cable is included after purchasing the multimeter, so you don't need to worry about the battery problem, it can be used immediately after charging.
