A Clamp Meter is a type of electrical measuring instrument used to measure the current flowing through a conductor without needing to disconnect it. It features a hinged jaw that can clamp around a wire, allowing for quick and safe measurements of alternating current (AC) or direct current (DC). This tool is essential for electricians and technicians who need to monitor electrical systems. In addition to measuring current, many clamp meters also offer additional functions, such as measuring voltage, resistance, and continuity. They are commonly used in various applications, including residential, commercial, and industrial settings, making them versatile tools for electrical diagnostics and troubleshooting.
