A Portable AC Meter is a device designed to measure various electrical parameters in an alternating current (AC) electrical system. They are simple devices used to quickly check the presence of AC voltage in a circuit and often have LED indicators to show the voltage status. These meters are portable, meaning they can be easily carried and used in different locations for measuring and troubleshooting electrical systems. They combine the functionalities of a clamp meter and a power meter and can measure AC current, voltage, power, and other parameters. Portable AC Meter come in various types, each designed for specific measurement tasks.
