The Tekneka M406 is a high-precision digital multimeter designed for professionals and industrial users. It accurately measures AC/DC voltage (10μV to 1000V), AC/DC current (10μA to 10A), resistance, capacitance, frequency, duty cycle, temperature, continuity, diode test, and NCV, with True RMS (TRMS) readings for reliable results. Its versatile functions, including measurement hold, relative zero correction, and auto/manual range selection, make it suitable for a wide range of electrical and electronic tasks.
