377 FC and 378 FC non-contact, voltage true-RMS, AC/DC clamp meters minimize shock risk by making accurate non-contact voltage measurements without test leads. They use Field-Sense technology to make testing faster and safer without touching live conductors. Users get accurate voltage and current measurements through the clamp jaw by clipping the black test lead to any electrical ground, putting the clamp jaw around the conductor, and seeing reliable, accurate voltage and current values simultaneously on the dual display.
Both clamp meters offer complete three-phase voltage and current tests in three quick 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 the user’s smart phone, and saved to the cloud via Fluke Connect software, eliminating the need for handwritten notes or complicated math. With Fluke Connect, users can also remotely log, trend, and monitor measurements to pinpoint intermittent faults. This data gathered can be used as a basis for designing a preventive maintenance program.
378 FC also includes a unique power quality indicator that automatically senses PQ issues related to current, voltage, power factor, or any combination of the three, while capturing voltage and current measurements. With this PQ indicator, it’s easy to quickly determine if an upstream supply problem exists or if there’s a downstream equipment problem.
These clamp meters also have an iFlex flexible current probe that can measure AC current as high as 2,500 A even in tight spaces. They also feature a TPAK magnetic hanging kit with a 9-inch (23-cm) hanging strap that allows the clamp to be hung wherever it’s needed, a premium carrying case, TL224 test leads, TP175 twist-guard test probes, and an AC285 black grounding clip.
