A Digital Multimeter (DMM) is an essential handheld device used to measure voltage, current, resistance, and sometimes additional parameters like capacitance and frequency. Featuring a digital display, it provides precise and easy-to-read measurements for troubleshooting and testing electrical circuits. Ideal for electricians, technicians, and hobbyists, a digital multimeter is indispensable for diagnosing electrical problems and ensuring system safety and performance.
