Megger PMM-1

The AVO PMM-1 Power Multimeter Multi-function Measuring Instrument is a portable, battery or line operated, multi-function measuring instrument designed to measure ac primary and secondary currents, voltage power, reactive power, phase angle and frequency of single and three-phase systems. A high speed recording feature can capture starting currents of three-phase motors. All measured values are displayed on a large easy-to-read graphic display. RS-232 data and parallel printer ports are provided.

Features

• Battery and line operated, with an automatic, built-in charger.
• Rugged, ergonomic and lightweight plastic enclosure.
• Three independent voltage and current channels with a built-in timer.Ability to input any current transformer ratio up to a ratio of 9999:1 or 9999:5.
• Simultaneously measures and displays voltage, current, phase angle, power, reactive power, power factor and frequency of single or three-phase systems.
• Measures neutral current when measuring three-phase currents.
• Wide current and voltage operating ranges.
• High-speed measurement mode with up to 1200 sets of readings in single-phase mode and up to 400 sets of readings in three-phase mode.
• When in timer mode, the phase angle between the voltage and current is measured and displayed eliminating the need to change to the single-phase mode to obtain phase angle readings.
• Accurate phase angle measurement at low current levels.
• Phase angle measurements can be displayed as lagging or leading angles.
• Data storage for saving measured values.
• Autoranging to reduce test time.
• Measurement of primary currents, using optional clamp-on CT
