RATED LEVEL CONTROLLING METHOD FOR ELECTRONIC WATTHOUR METER

摘要

PROBLEM TO BE SOLVED: To provide a rate level controlling method for electronic watthour meter capable of simplifying circuit constitution by avoiding multiplication. SOLUTION: A method for controlling the rated level of electronic watthour meter outputting 1 pulse as an electric energy pulse at every time an accumulation value of digital value proportional to power exceeds a specific output reference value set in an output reference value register 6 controls the rated level by adding the rated level controlling value (b) to the output controlling value (a) of the output reference value register 6.
