The Fluke 393 FC CAT III 1500 V True-rms Solar Clamp Meter with iFlex is designed for solar photovoltaic (PV) installation technicians and maintenance professionals who work in high voltage DC environments: PV arrays, wind power, electric railways, data centers battery banks for uninterruptible power supplies. The clamp meter will measure up to 1500 V DC and 1000 V AC with test leads, and up to 999.9 A DC or AC through the clamp jaw. The included iFlex flexible current probe extends AC current measurements up to 2500 A. The 393 has a thin jaw, giving you access to cables in crowded combiner boxes. Plus, the test leads are designed with your work in mind, and are also rated to CAT III 1500 V DC.
