Abstract:
A register for coupling to a meter, the meter including an eddy current disk and shaft which rotate in response to the rate of energy consumption by a load being metered thereby, and a shutter mounted to the shaft, said register comprising a microprocessor, a non-volatile memory, and a disk sensing optics assembly, said disk sensing optics assembly configured to generate a predetermined number of pulses for each complete disk revolution, said register further configured to communicate metering data with a service control center, said microprocessor programmed to:upon register power up, and if load profile recording is enabled, initialize a load profile interval timer to a load profile interval length;record load profile data in said non-volatile memory when said timer expires; andif said register loses power:end a load profile interval in progress;set an outage bit;record interval pulse data for the interval in progress in said non-volatile memory;record the time and date of the power outage in a history log; andupon power restoration after an outage, transmit a request for time message from said register.
