Analog Devices AN-950 ADE71xx/ADE75xx Meter Calibration Guide
This application note describes the calibration procedures for ADE71xx/ADE75xx series single-phase energy meters. The first part details the calculation of constants required for active power, RMS current/voltage, apparent power, and reactive power calibration, including examples using a reference meter or precise source.
The second part outlines how to use LabVIEW™ calibration software designed specifically for interaction with ADE71xx/ADE75xx reference designs. It covers determining the isolated COM port, downloading firmware, accessing EEPROM calibration constants, and performing power and RMS calibrations via the software interface.
