Electricity consumption meter, meter and apparatus for responding to schedule daily cyclic events

摘要

A time-of-use meter ÄFigure 1Ü is provided with a means (U5, Table III) for storing a plurality of identifiers ÄFigures 2,3Ü that each represent a cyclic event. These cyclic events are described in such a way that a single word of storage is sufficient to represent numerous occurrences of the cyclic event over a period of many years. A microprocessor-based (U4) calendar programme is provided with the means for storing a plurality of cyclic event identifiers (50) and special event identifiers (60) in a manner which significantly reduces the required memory storage within the microprocessor and its peripheral memory devices.
