INTRODUCTION
This application note describes the functionality of the SA2002D metering integrated circuit using the PM2002DP evaluation module.

The SA2002 enables the meter manufacturer to build a meter that measures the energy consumption, and records it to a mechanical counter. Energy flow direction as well as energy metering activity is indicated by means of LEDs. This application note will focus on the practical use of the SA2002D, more detailed information specific to the SA2002D can be found in the applicable datasheet.
