ABSTRACT:
An electric watthour meter includes apparatus for delaying a seasonal rate change until data accumulated in the meter is read out. Dates in a rate-change library, consisting of dates on which a rate change is authorized, are compared each day with the current date. When a match between a rate-change date and the current date is found, an arming signal is generated. The arming signal remains ineffective until a reset signal is generated at the completion of meter reading. Following the reset signal, the arming signal is reset.
