78M661x Calibration Procedure


The Teridian 78M6612, 78M6613, and 78M6618 are a family of integrated system-on-chip (SoC) solutions for implementing single-phase AC-power and energy measurement. The devices have firmware available that includes a simple calibration procedure for temperature, voltage, and current measurements. An effective calibration procedure reduces sensor cost by allowing the use of less precise components. This application note discusses the calibration procedure for various measurements, the system setup, and the calibration registers and calibration commands. Read full article.
