Method and apparatus for electronic meter testing.

摘要

An electronic energy meter senses input voltage and current signals and processes them to generate a plurality of power measurements. The meter includes a processing system (14/16) for selecting one of the plurality of power measurements and for generating a pulsed test signal related to the selected power measurement for testing the operation of the meter, and an optical communications port (40) coupled to the processing system for transmitting the pulsed test signal from the meter to a testing device external to the meter.
