The Fluke 301D AC/DC Clamp Meter is a versatile tool that is designed to make your job easier. Its lightweight and compact body make it easy to carry in your pocket, and its slim and thin jaw allows it to fit into tightly packed wires. With the ability to test current, voltage, resistance, continuity, frequency (voltage and current), capacitance, and diode testing, the 301D can handle multiple test needs in a single tool. And with its AC/DC function, it can be used for a wide range of applications, including those requiring DC testing, such as photovoltaics (PV) and wind power, communications, data centers, and more.
