Based on a 51-chip microcomputer design, this multifunction meter integrates capacitance measurement, inductance measurement and frequency measurement. - It can measure various non-polar capacitors, polar electrolytic capacitors, inductors and frequencies. - The multifunction rotary gearbox lets you select different functions for easier and more convenient measurement. - It supports self-assembly and soldering practice, helping you learn how a microcontroller is applied and the measurement principles of frequency, capacitance and inductance. - A high-resolution, large LCD display shows digital icons clearly for easy reading. Use scenarios - Electronics repair and testing: verify capacitor values (including non-polar and polarized electrolytics), check inductors, and measure frequency in signal paths. - Education and hobby projects: practice assembling the kit, learn microcontroller applications, and experiment with measurement principles. - Circuit design and prototyping: quickly switch between capacitance, inductance and frequency measurements while evaluating RC, RL and LC networks.
