  • Voltage and current measurements with FieldSense™ technology

    The Fluke 377 FC True-RMS current clamp offers faster and safer testing, all without touching a live wire, with FieldSense™ technology. You get accurate voltage and current measurements through the pliers' jaws. Simply clamp the black test wire to an electrical earth wire, place the jaws of the pliers around the wire and see reliable, accurate voltage and current readings on the screen.

    Measure extremely high currents with the iFlex® sensor

    Use the included iFlex flexible current probe to measure AC current up to 2500 A AC. The iFlex flexible current clamps provide access to thick conductors in tight spaces.

    Fast, simple, full 3-phase measurements

    • Complete 3-phase voltage and current testing in three easy steps
    • Full set calculating phase-to-ground and phase-to-phase values
    • Displayed on your smartphone and stored in the cloud via Fluke Connect software
    • Phase rotation calculated and displayed on Fluke Connect software
    • No more handwritten notes or complicated arithmetic.

    Easy to read, easy to use with tools included

    Your job gets easier when you use the 377 FC current clamp. The display turns green when a stable FieldSense reading is detected. Visual transit also provides a bright green display for easy detection of transit in noisy areas.

    Record, analyse and share results with Fluke Connect® software

    Fluke Connect software lets you remotely capture, track and monitor measurements to find alternate problems. With Fluke Connect, you can also collect data as a basis for a preventive maintenance programme.
