ABSTRACT:
A high speed multiple range measurement system that selects on a sample by sample basis the range having the highest resolution and accuracy for which an overload condition does not exist. A plurality of analog to digital converters sample and convert an analog of a physical quantity, such as voltage, current, temperature, strain etc. to a plurality of digital data steams, each having a full scale range representing a fraction of an expected maximum value of the physical quantity. Corresponding overload detectors test the respective data streams for an overload condition. A data selector chooses the data stream having a full scale representing the smallest fraction of an expected maximum value based on the overload detector status.
