摘要

A method for synchronizing the internal time of day in the case of an electronic evaluation unit (5) of a supply meter (1) with the actual time of day, in which the evaluation unit (5) a time-dependent performance profile with a measurement interval with a maximum reduction is created, characterized in thata. in the case of a synchronization procedure, which can be caused by the shortening of an unsynchronized old measuring interval the synchronization is displaced within the old to be shortened, a new maximum measuring interval would occur, namely until no old measuring interval with a new maximum occurs, andexample, in the case of a which can be caused by the synchronization procedure, the extension of a measuring interval is displaced, the synchronization,if α within the unsynchronized old measuring interval a new maximum occurs, in which case a new measuring interval in the cycle of the unsynchronized measuring intervals and started again, it is checked andβ. if within the new extended measuring interval a new maximum would occur, in which case a new measuring interval with a new measured value, which, if appropriate, a new maximum as a basis..
