The HIOKI CM3286-50 clamp power meter goes beyond simple current measurement to deliver comprehensive AC power analysis directly on live conductors. By combining clamp-type current measurement with voltage test lead inputs, it calculates active power (W), reactive power (VAR), apparent power (VA), and power factor — parameters essential for energy auditing, power factor correction verification, and electrical billing dispute investigation.
With a power measurement range of 5 W to 360 kW (single-phase), the CM3286-50 serves everything from small commercial circuits to large industrial loads. It supports 3-phase measurements through sequential single-phase measurement and can detect phase sequence on live lines. Harmonic analysis from the 1st to 30th order is available via the optional HIOKI Z3210 Wireless Adapter and GENNECT Cross app — a powerful tool for identifying harmonic-related energy losses and equipment overheating without additional instrumentation.
