Abstract
A solid state electronic pulse scaler uses the ratio of two integers to control a ratio of its input and output frequencies. In one embodiment, the pulse scaler is used as a calibration device to adjust for manufacturing tolerances in an electric metering device. In another embodiment, the pulse scaler is used to provide a pulse-initiator output to external circuits. A further embodiment includes both of the above functions in a single device. A switch-selectable control is provided to determine the consequences of input pulses generated during reverse rotation of a meter disk. The reverse pulses may be used to generate output pulses on the same, or a separate, channel as that employed for forward pulses, ignored, or temporarily stored and subtracted from ensuing forward pulses.
