Fluke’s 377 FC and 378 FC non-contact voltage true-RMS AC/DC clamp meters measure voltage and current simultaneously without touching a live wire, and use field-sense technology.
Both clamp meters offer three-phase voltage and current tests in three steps. A full set of phase-to-ground and phase-to-phase values are displayed on the meter. These measurements along with phase rotation information are displayed on a smartphone and are saved to the cloud via Fluke Connect software.
The 378 FC includes a power quality indicator that senses PQ issues, relating to current, voltage, or power factor automatically while capturing voltage and current measurements.
The clamp meters come with an iFlex flexible current probe that can measure ac current as high as 2500 A. Also included are a TPAK magnetic hanging kit with a nine inch (23 cm) hanging strap, a premium carrying case, TL224 test leads, TP175 twist guard test probes, and an AC285 black grounding clip.
