Measurement system for machine parts
First Claim
1. A measurement system for machine parts comprising a case, a support means for movably clamping the case to the support whereby the position of the case may be varied relative to a machine part, a measuring member extending from said case for engagement with the machine part, said measuring member coupled to a transducer, said case having a configuration with at least one circular face, a plurality of groups of segments disposed in a circle around the periphery of said face, said transducer having an analog output, an analog-to-digital converter, a signal processing circuit, said circuit having an output coupled to a decoder driver for the circular segments and a decoder driver for the digital display, the central portion of said face being provided with an opening, a plurality of binary segments arranged in a predetermined manner within said opening to provide a digital display, a digital display within said opening displaying at least three significant digits, two digits of said display corresponding to the analog reading of the plurality of radially extending segments mounted in the circular pattern on said face, the third digit corresponding to an interpolated numeral of the analog display.

Abstract
A measurement system that is particularly adapted for the use in machining of parts or measuring finished parts is disclosed. The system includes a support means upon which is movably clamped a casing, the casing having a measuring member extending therefrom that will engage the part that is being machined or measured. On the casing there is mounted a composite indicator that obtains a digital readout as well as an analog dial readout of the same units which allows a user to search for maximum and minimum readings, as well as providing for extended resolution in digital form of the interpolation between two analog scale points on the dial.
