Product Detail



Multi-function Multimeter Resistance Test D/ACV D/ACA   Backlight Manual Function Auto Off Frequency Multimeter

301B is a true RMS automatic scanning digital meter. There is no need to turn the dial to select functions. According to the input voltage/current/resistance/current difference, the meter will automatically identify and measure.The meter is powered by 3.2V/5000mA lithium battery. The meter uses a large LCD display and a boost power supply. Even at the edge of the 2.3V low battery, the backlight and the ultra-high brightness of the flashlight can be guaranteed.The backlight can be long bright or automatically turn off after 15 seconds.This series of meters can automatically identify DC voltage and AC voltage, AC/DC current 10A, resistance, without any switching, but also can be manually switched to measure capacitance, on-off test, and other parameters, is a superior tool meter, is the ideal tool for laboratories, factories, radio enthusiasts and families.
