摘要: 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 plurality electrical energy measuring devices. Sample values continuous counts are and input to microprocessor wherein each sample value has previous subtracted therefrom. The difference is added an interval sum stored random access memory. sums, together with real time information clock, cartridge according predetermined format. clock maintained synchronization frequency line voltage microprocessor.
