    摘要: A programmable system for providing a programmable ratio of output pulses to input pulses. The programmable system receives pulses from an electric power meter and outputs a programmable number of pulses representing a number of kilowatt hours consumed. Various electric power meter disk patterns can be processed by the programmable system. The programmable ratio can be applied via input pins and/or via an external memory.
