ABSTRACT:
A restraining means of mildly magnetic material is adjustably implanted in the rotor disc of a conventional watthour meter. The restraining means interacts with a magnetic field generated by the meter's damping magnet to stop the disc from turning when the rate of energy consumption in the metered circuit is below a predetermined rate. The predetermined rate can be altered by varying the radial distance between the center of the disc and the restraining means and by varying the amount of magnetic material passing through the field of the damping magnet.
