Abstract:
1. A process for determining and displaying a measurement of relative movement between a digital reader head and a reference element comprising: operably engaging the reader head with the referenced element; determining measurements of relative movement between the reader head and the reference element in a selected units of measurement according to a predetermined decimal measurement resolution; electronically displaying on said reader head corresponding decimal measurements in said selected units of measurement according to a predetermined decimal display resolution; converting said measurements within discrete predetermined decimal ranges to respective equivalent fractional measurements in said selected units of measurement such that all decimal measurements within a respective said decimal range convert exclusively to a single equivalent fractional measurement representative of and corresponding to said respective decimal range; and electronically displaying on the reader head said single equivalent fractional measurement in said selected unit of measurement and according to a predetermined fractional display resolution simultaneously with and adjacent to each decimal measurement in a respective said decimal range; and providing that each said decimal range is smaller than said predetermined fractional display resolution such that no equivalent fractional measurement is displayed simultaneously with an adjacent to said decimal measurements and said decimal measurements alone are displayed when the reader head determines measurements outside of said discrete predetermined decimal ranges.
