Abstract
A solid state electricity demand recorder (10) is controlled by a programmable microprocessor (38) to obtain energy demand survey and billing data. The accumulated count of pulses during a record interval is compared with an encoded register reading obtained from an electricity meter (30) at the end of the record. If there is acceptable correlation between the accumulated count and encoded meter reading, the interval pulse counts associated with that record are deemed verified. The recorder then downloads the recorded demand data to a central computer at a preselected time over a communications line. The recorder is receptive to communications and commands from the central computer at times other than the normal preprogrammed data downloading time by detecting a particular number of rings.
