Abstract
An electricity meter performs a self-calibration operation. According to an exemplary embodiment, the meter includes a measurement circuit for generating power information representative of measured power. A controller is operably coupled to the measurement circuit and includes an input for receiving reference standard information. The controller compares the power information generated by the measurement circuit to the reference standard information and generates a compensation signal in dependence upon the comparison. The compensation signal is used to calibrate the measurement circuit. Preferably, the meter is capable of being electrically connected to, and calibrated concurrently with at least one other meter.
