1. An electrical metering device comprising:
- metering means for measuring power consumption of an electrical load associated with the electrical metering device;
register means, operatively connected to said metering means, for tabulating load profile data related to the measured power consumption of the associated electrical load and for storing the tabulated load profile data in a plurality of load profile data blocks; and
means for bidirectionally communicating between said register means and an external communications device wherein said communicating means comprises;
means for receiving control signals, from the external communications device, indicative of a predetermined format of the load profile data to be transmitted, the respective load profile data blocks to be transmitted, the respective load profile data blocks to be skipped and a predetermined order of transmission of the designated load profile data blocks; and
means for transmitting the load profile data blocks designated to be transmitted, to the external communications device, in response to the predetermined format and predetermined order of transmission of the load profile data blocks indicated by the control signals, and for skipping the load profile data blocks designated to be skipped such that only a portion of the tabulated and stored load profile data is transmitted.

Abstract
The present invention, in one embodiment, is an algorithm for implementation in a meter register and an reading device. In the one embodiment, the present invention enables selecting a display table to be read from the register, updating the billing read date and time in the register, reversing the order in which load profile (LP) data is transmitted from the register to the reader, specifying the number of LP intervals to be read from the register, and specifying the number of intervals to skip when reading from the register.
