This is a multi-functional, auto ranging, true RMS digital multimeter with 9999 counts LCD display. This multimeter is a very practical tool for electricians, hobbyists, and general household use. It can measure AC/DC voltage, AC/DC current, resistance, capacitance, frequency, duty cycle, diode and continuity with square wave output. Features: Measure AC/DC voltage, AC/DC current, resistance, capacitance, frequency, duty cycle, diode and continuity with square wave output. Large LCD display with switchable backlight, easy to read, maximum display 9999 counts with true RMS. Auto power off after 15 minutes without operation, energy-saving and safer. High precision, portable handheld size, and easy to carry. Max./Min. value test and relative measurements, with a back bracket at a 45 angle for easy readings and hands-free use. Data hold, low battery indication and backlit LCD with large digits for visibility in dimly lit areas. Widely used in laboratory, factory and family for circuit or instrument maintenance and repair.
