6612_OMU_S2+2_URT_V1_14 Firmware Description Document

By: Kathy Reffert

Abstract: This document describes the firmware 6612_OMU_S2+2_URT_V1_14, which can be used with the 78M6612 power and energy measurement IC. This firmware provides simple methods for calibration, relay control, and access to measurement data such as watts, voltage, current, accumulated energy and line frequency. It is optimized for measurement of up to two single phase AC loads using current shunts as the current sensors, but current transformer (CT) sensors can also be used, if desired.
