Introduction
This manual explains how to use the iMeter 6 Advanced Power Quality Meter. Throughout the manual the term
“meter” generally refers to all models.
This chapter provides an overview of the iMeter 6 meter and summarizes many of its key features.
1.1
Overview
The iMeter 6 is CET’s latest offer for the advanced Power Quality Monitoring of Incomers and Critical Feeders for
Utilities, Data Centers, High-Tech Manufacturing Facilities and Heavy Industries. Housed in an industry-standard
DIN form factor measuring 96mmx96mmx119.5mm, the iMeter 6’s compact size is perfectly suited for today’s
space restricting environment. The iMeter 6 features quality construction with metal enclosure, advanced Power
Quality and Revenue-Accurate measurements, high-resolution Waveform Recording capabilities, comprehensive
Data Logging with 1GB memory, extensive I/O and a user friendly, IPS Color Dot-Matrix Display @ 320x240. It
also provides either an I4 Input for Neutral Current measurement or a 0/4-20mA Analog Input for measuring
external transducer signal such as Residual or Leakage Current. With a standard 100BaseT Ethernet Port and a
RS-485 port with Modbus TCP/RTU support, the iMeter 6 becomes a vital component of an intelligent Power
Quality Monitoring System.
Following is a list of typical applications for the iMeter 6:
▪
Class 0.2S Revenue Metering
▪
Power Quality Monitoring of Main Incomer or Critical Feeder
▪
Utility, Industrial and Commercial Metering
▪
Substation, Building and Factory Automation
▪
Low, Medium and High Voltage applications
▪
