Megger PMM-1 Power Multifunction Measuring Instrument

Overview

The Megger PMM-1 is a portable, three-phase power multifunction measuring instrument that brings a full set of electrical measurements together in one handheld unit. It reads AC/DC voltage, AC current, active and reactive power, power factor, phase angle and frequency, and simultaneously captures all harmonic content up to the 49th harmonic on any selected channel.

With three independent voltage and current channels, high ±0.05% voltage accuracy and phase-angle resolution to 0.08°, the PMM-1 is precise enough for protective-relay testing and phase-sequence checks, yet portable enough for monitoring power at the service entrance. A large graphic LCD, RS-232 and printer outputs, and up to 10 hours of battery operation make it a versatile field and workshop instrument.
