Megger PMM2 Multi-function Measurement Instrument

Description

Advanced Multifunctional Electrical Testing: PMM2 Overview

The Megger PMM2 Multi-function Measurement Instrument stands as a state-of-the-art tool developed specifically for diverse electrical measurement, monitoring, and analysis needs in both single-phase and three-phase electrical systems. Designed for portability, ruggedness, and high precision, the PMM2 is equipped with a vibrant onboard LCD touchscreen, delivering user-friendly navigation paired with robust multi-colored graphics. It combines the essential functions of voltage, current, phase angle, frequency, power, reactive power, power factor, and harmonic measurement in a single package. The intuitive software architecture, menu-driven operation, and built-in report generator make the PMM2 a versatile asset for both field engineers and laboratory professionals. Its integration of a high-speed sampling engine and extensive onboard memory places the instrument among the most efficient, accurate, and reliable measurement devices available for today’s demanding electrical environments.

Unique Design with Powerful Operating Features Included

At the core of the PMM2’s design are four completely isolated voltage and current channels, capable of simultaneous measurement and display—making it possible to observe up to four voltages and four currents at once. The instrument features both standard and rugged model options, tailored to withstand varying operational conditions. With an integrated lithium-ion battery offering about four hours of continuous operation, it ensures reliability even in locations lacking immediate AC power. The PMM2 further enhances its utility with a comprehensive set of onboard analytics, including high-speed data sampling at 28.8 k samples/sec and non-volatile memory capable of storing over 60 minutes of recorded data. The touchscreen is engineered for clarity and ease-of-use, allowing stakeholders to configure screens, alter display nomenclature, adjust waveform and color settings, and quickly access any meter or report function as required.

Specialized Applications Across Industrial Environments Explained

The PMM2 Multi-function Measurement Instrument excels in a wide spectrum of electrical industry applications. In general electrical systems maintenance, it facilitates rapid diagnostics and troubleshooting by delivering precise rms readings for voltage, current, and power factor. For electrical machine repairs, the device can capture detailed transients such as motor starting currents, voltages, and the associated power draw for effective analysis and preventive maintenance. During protective relay testing, the PMM2 offers rapid, accurate relay operation verification via its built-in timer and event logging capabilities, simplifying both commissioning and periodic inspection procedures for substations and utility infrastructures. Finally, the PMM2 shines in revenue meter installation monitoring—quickly measuring phase-to-phase voltages, single-phase currents, and providing direct readouts of phase angles, vastly improving efficiency for meter installation and calibration tasks.

Seamless Integration Enhances Operational Workflows Significantly

A highly regarded user interface, set via the PMM2’s touchscreen, gives operators direct manual control along with at-a-glance readings—even in direct sunlight, thanks to its high-brightness and contrast display. Extensive configuration options let users define custom nomenclature (e.g., phase labelling conventions like ABC, RST, or ACB), language preference, and how phase angle or harmonics data is mapped. The PMM2’s vector graph display shows phase relationships, while dedicated waveform views allow simultaneous monitoring of voltage and current across selected phases. Built-in binary inputs, programmable to suit various triggering thresholds and conditions, further reinforce its adaptability. The flexible system can even store and export custom-generated test reports for record keeping or regulatory compliance (such as NERC audits), helping improve overall workflow productivity while managing data security and archiving.

High-Performance Measurement and Data Analysis Tools

Built from the ground up for precision, the PMM2 delivers high-accuracy measurements over wide ranges: voltage from 0 to 1000V (AC/DC), and current from 0 up to 100A (with special provision for low-level AC/DC and clamp-on transformer inputs). The device ensures minimal reading drift with accuracy tolerances as tight as ±0.05% for voltage and current measurements within specified ranges, and ±0.08° for phase angle at higher input levels. All measured quantities—ranging from real and reactive power to power factor and frequency—appear in enlarged, easily-interpreted formats. Harmonics up to the 50th order are concurrently displayed for all selected channels, and a built-in timer processes events, motor currents, and other time-dependent fault analyses in cycles, milliseconds, or seconds, with resolutions down to 200 μs. The PMM2’s sampling system enables rapid, accurate data acquisition for real-time monitoring or post-event forensic evaluation.

Safe Operation and Robust Environmental Resistance

Operating safety and durability are deeply embedded in the PMM2’s design. Compliant with major international standards, the instrument features 1200V input isolation and CAT IV 600V, CAT III 1000V overvoltage protection. The battery is RoHS-compliant, air-travel safe, and includes robust charge/exhaustion protection. With environmental ratings such as IP20 ingress protection, operating temperature from -15°C to 55°C, and transit-tested drop and vibration resistance, the device can tackle the harshest industrial sites, substations, and field environments. The instrument’s enclosure is lightweight yet tough, ensuring high mobility and resilience, while the touchscreen maintains optimal readability throughout its extreme temperature range.

Ordering Options, Supported Accessories, and Global Guarantee

Available in standard and rugged versions, the PMM2 family offers tailored solutions for region-specific power cord selections (American, Continental Europe, UK, and International variants). Each unit includes standard accessories such as power cords, a 7ft Ethernet communication cable, instruction manual on USB, and a soft carry case (PMM2 only). Numerous optional test leads, adapters, clamp-on current probes, and accessory kits further extend its capability for specialized scenarios.
