ABSTRACT:
A solid-state event-logging system records the occurrence of specified events in a removable, solid-state, memory cartridge. Counters continuously count pulses produced by a plurality of electrical energy measuring devices. Sample values of the continuous counts are produced and input to a microprocessor wherein each sample value has the previous sample value subtracted therefrom. The difference is added to an interval sum stored in a random access memory. The interval sums, together with real time information produced by a clock, are input to the memory cartridge according to a predetermined format. The clock is maintained in synchronization with the frequency of the line voltage by the microprocessor.
