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.

Solid state electronic pulse scaler using ratio of two integers

An electronic demand register for an electric meter includes a volatile storage for normal processing of data and a non-volatile storage into which data is serially written upon the occurrence of conditions which may threaten the integrity of such data and from which the data is again retrieved when the condition no longer exists. The data formats for transmission of the data to the non-volatile memory and for receiving it therefrom do not agree with the data formats which the volatile storage must have. A communications buffer assembles a data package for transmission to the non-volatile memory which has a format which can be suitably serially transmitted to the non-volatile memory and be properly interpreted there due to the manner in which the non-volatile memory recognizes and stores data. In addition, the communications buffer receives the serial data from the non-volatile memory and, by left shift and selection of only valid portions of the data, assembles data suitable for transmission to the volatile memory.
