CHAPTER 1: OVERVIEW
PQMII POWER QUALITY METER – INSTRUCTION MANUAL
Voltage and current waveforms can be captured and displayed on a PC with the EnerVista
PQMII Setup Software or EnerVista Viewpoint. Distorted peaks or notches from SCR
switching provide clues for taking corrective action.
Alarms, triggers, and input/output events can be stored in a 150-event record and time/
date stamped by the internal clock. This is useful for diagnosing problems and system
activity. The event record is available through serial communication. Minimum and
maximum values are also continuously updated and time/date stamped.
