An AC Meter typically refers to a device designed to measure various electrical parameters in an alternating current (AC) electrical system. A digital multimeter can measure AC and DC voltage, AC and DC current, resistance, continuity, and other parameters. A versatile tool that combines several functions in one device.AC meters come in various types, each tailored for specific measurement tasks. It provides readings in volts and is used to determine the voltage level in a given system. Furthermore, the AC Meter is commonly used for energy auditing and monitoring power usage.
