Patent ID: 7899630

Claim:
A metering device operating on a secondary analog waveform output by an external transformer assembly receiving a primary waveform, the metering device comprising: an internal transformer, wherein the internal transformer receives the secondary waveform and generates a stepped-down output signal; first biasing circuitry, wherein the first biasing circuitry receives the output signal from the internal transformer and generates a first digital signal within a first range, the first digital signal having a value proportional to the output signal; second biasing circuitry, wherein the second biasing circuitry receives the output signal from the internal transformer and generates a second digital signal within a second range, the second digital signal having a value proportional to the output signal; and a processor assembly in communication with the first biasing circuitry and the second biasing circuitry, wherein the processor assembly executes first operational software for performing a first function having first biasing requirements using the first digital signal to generate a first output and wherein the processor assembly executes second operational software for a second function having second biasing requirements using the second digital signal to generate a second output, the first operational software operating within the first range and the second operational software operating within the second range.
