Abstract
A digital, bow-type measuring instrument is disclosed which provides rapid adjustment of the position of a measuring bolt with respect to an anvil over the entire measuring range. The instrument is used by rapidly translating the bolt into position such that the object being measured is positioned between the anvil and the bolt. Thereupon, the bolt is locked in position with the aid of a locking system so as to fix the measuring bolt in position with great rigidity while applying a predetermined measuring force to the bolt. In this way, an instrument is provided which makes possible precise measurements of heavy or fixed objects by means of a bow-type measuring instrument which allows rapid shifting of the measuring bolt.
