Avo multi-amp pmm-1 power multi-function instrument
Used PMM-1 in good condition with some scuffs on the exterior. Works fine and the the battery holds the charge quite well.
Power Multimeter Multi-function Measuring Instrument
Simultaneous measurement and display of all three-phase system parameters
Accurate phase angle measurement at low current levels
Versatile, menu-driven instrument with a built-in timer and data-logging
The PMM-1 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.
