Abstract
An AC electric energy meter includes a metering sequence logic control circuit for receiving pulses responsive to an AC energy quantity to be measured. Electric energy parameters are measured by the control circuit as it concurrently registers clock time and calendar data. A programmable rate selection table controls variable time intervals for accumulating different parameters during predetermined daily time measuring categories corresponding to different billing rates. The rate selection table includes plural rate switch control points defining daily measuring times nominally on a day of the week basis. A programmable yearly date code table designates days during the year for still different daily code times. The measured parameters are stored in separate electronic registers so as to have coded values of kilowatthours and/or kilowatt demand for direct electronic display in a multiplexed and reoccurring sequential order.
