Single-phase multi-tariff energy meter
Introduction
This user manual describes the functions and features of the single-phase multi-tariff energy
meter.
The reference board is an integrated system designed to provide a complete, ready-to-use
energy meter application. It is a medium-end solution for power metering, using the
ST72F321 microcontroller, the M41T94 Real Time Clock, the M95256 EEPROM and the
STPM14 energy meter ASSP device.
The multi-tariff energy meter reference board implements several features including multi-
tariff management, absolute and average maximum demand calculation, two types of
tamper management and power failure management. It can therefore be used as a platform
for evaluation and development of meter applications.
The aim of this guide is to provide:
■ Procedures for getting the reference board functioning quickly
■ An overview of the implementation of meter main features
■ The information required to be able to customize meter features.
