Abstract

This electronic maximum-demand meter which consists of a kilowatt hour meter and a maximum-demand mechanism exhibits a microcomputer with non-volatile memory in the maximum-demand mechanism. To save the various values of the maximum demands of the month and of the state of the counting mechanism in the event of mains failure, regular refreshing of the memory contents is provided, the interruption of the current consumption metering and transmission of the data into the non-volatile memory being initiated by a subroutine. In addition to the current data in each case, the user-specific values are also entered in the memory.
