Pocket-Sized 3 5/6-Digit Automatic Digital Meter Experience stable performance and high accuracy with our pocket-sized digital meter, perfect for laboratories, factories, radio enthusiasts, and families. Its clear readings and overload protection ensure reliability in every usage. Features: Compact and portable design, easy to use and operate. Accurate and real-time measurement of RMS values across various voltage waveforms without distortion. Eliminates the effects of lead resistance, distributed capacitance, and interference signals. Clamp unit measures vertically through the center of the hole. Powered by two AAA 1.5V batteries (not included). The large LCD display and boost power source maintain high brightness for the backlight and flashlight, even with a low battery. Automatic backlight feature switches off after 15 seconds to conserve battery. Functions: AC-DC voltage, AC current (AC current 8202/AC-DC current 8203), resistance, capacitance, frequency, diode, buzzer, true RMS, NCV, square, TEMP, flashlight.
