The first current clamp with measurement category CAT III 1,500 V. The true RMS current clamp Fluke 393 FC is designed for technicians working in DC high-voltage environments: PV systems, wind energy, electric railways, and uninterruptible power supplies for data centers. It measures up to 1,500 V DC, 1,000 V AC, and up to 999.9 A DC/AC via the clamp. The included flexible current sensor iFlex extends AC measurements up to 2,500 A. The device features a slim clamp that allows access to wires in tight junction boxes. The test leads are designed for work up to 1,500 V DC and are specified according to CAT III 1,500 V. Other key features include: - IP 54 rating: ideal for outdoor work, on PV and wind power systems. - DC power measurement, displaying values in kVA. - The polarity indicator warns of accidental miswiring with an audible signal. - The display lights bright green for continuity, making it ideal for work in dark and noisy environments. - Logging and reporting of measurement results via Fluke Connect software. For AC measurements, the included flexible current sensor iFlex provides excellent access to wires in tight spaces. It can be maneuvered through extremely small areas and delivers precise measurement results.
