Abstract
A modular electronic utility meter has a sensor portion that includes sensor devices and a memory device storing calibration and/or error information specific to the sensor devices. Such a sensor portion is designed for use with a corresponding measurement portion that extracts the calibration and/or error information from the memory in the sensor portion. The measurement module then employs the calibration and/or error information in its calculation of energy consumption information. The calibration information includes phase and magnitude error information for at least one of a current sensing device and/or a voltage-sensing device. That error information may include coefficients of a polynomial.
