ABSTRACT:
A measuring instrument of the caliper type which can be extended out, by means of extension pieces, to cover a wide range of linear dimensions. A mechanical scale gives the most significant figures of the measurement and the scale indicates a different range to match each extension piece employed. An electrical circuit gives the least significant figures of the measurement and the figures are presented together so that they can be read as a composite reading.
