Fluke 378 FC True-RMS AC/DC Clamp Meter with iFlex

The Fluke 378 FC True-RMS AC/DC Clamp Meter with iFlex features a unique power quality (PQ) function which is able to automatically detect PQ issues. When using Fluke’s FieldSense technology to perform measurements, the 378 FC is able to detect PQ issues relating to current, voltage or power factor. This functionality allows you to identify problems upstream or downstream of supply, effectively providing a quick indication of PQ issues at both incoming power or equipment level.

The unit can calculate a full set of phase-to-ground and phase-to-phase values, in addition to phase rotation. Complete 3-phase voltage and current tests can also be provided in just a handful of easy steps. All of this data can be viewed remotely via smartphone or uploaded to the cloud using Fluke Connect.

With its flexible design and large loop closure system, the included iFlex flexible current probe allows you to measure large conductors in small spaces up to 2500 A AC current. The Visual Continuity feature provides a bright green screen notification when detection is made, ensuring visibility in noisy work spaces.

The clamp’s kit includes a the TPAK Magnetic Hanging Kit, with a 9 inch hanging strap allowing you to hang your clamp wherever you need during use. A Fluke carry bag is also included, for secure transportation and storage.
