Chapter 1 Introduction
This manual explains how to use the PMC-D726M Digital Multifunction Meter. Throughout the manual
the term “meter” generally refers to all models. Differences between the models are indicated with the
appropriate model number.
This chapter provides an overview of the PMC-D726M meter and summarizes many of its key features.
1.1 Overview
The PMC-D726M Digital Multifunction Meter is CET’s latest offer for the low-cost digital power/energy
metering market. Housed in an industry standard DIN form factor measuring 72mmx72mmx71.8mm
(LCD) or 72mmx72mmx76.8mm (LED), it is perfectly suited for industrial, commercial and utility
metering applications. The PMC-D726M features quality construction, true RMS multifunction
measurements and a LED or LCD display. Compliance with the IEC 62053-21 Class 1 kWh Accuracy
Standard, it provides optimum Price to Value ratio and is a cost effective replacement for traditional
analog instrumentation, capable of displaying 3-phase measurements at once. The PMC-D726M
optionally provides Split-Core CT (SCCT) support for retrofit situations, two Digital Inputs for status
monitoring, two Digital Output for control, or one 0/4-20mA Analog Output for interfacing with 3rd
party SCADA system. The standard SOE Log records meter events such as power-off, setup changes, DI
status changes in 1ms resolution. With the optional RS485 port and Modbus protocol support, the PMC-
D726M becomes a vital component of an intelligent, multifunction monitoring solution for any Power
and Energy Management systems.
You can setup the meter through its front panel or via our free PMC Setup software. The meter is also
supported by our PecStar® iEMS Integrated Energy Management System.
Following is a list of typical applications for the PMC-D726M:
 Analog meter replacement
 Industrial, Commercial and Utility panel metering
 Substation, Factory and Building Automation
 Sub-metering and Cost Allocation
 Ideal for retrofitting with SCCT option
