Abstract
A summing module (10) and method for interfacing a compound meter with two metering signals to a plurality of different output devices for displaying or retransmitting meter data includes an enclosure (20), a summing circuit (32), networks (41) for setting a ratio between the two metering signals before they are summed, and a ratio between one of the input signals and an output signal, and output subcircuits (60, 65) for providing signals compatible with at least two meter data output devices. The module (10) also provides for testing of the inputs for short circuits and open circuits and passing the result on to the output.
