About the 377 FC

The Fluke 377 FC uses FieldSense technology to measure voltage and current through the clamp jaw, without metal-to-metal contact with a live conductor: clip one lead to ground, close the jaw and read both values. Three-phase checks take three quick steps, and it comes with an iFlex flexible probe and Fluke Connect wireless.
