ABSTRACT:
A linear measuring instrument having a pair of measuring tips mounted on respective jaws moveable relative to one another along an elongated beam particularly adapted for measuring inside dimensions has a digital display unit responsive to display increments of movement of one jaw relative to the beam on which the jaw is slidingly mounted. The pair of measuring tips are spaced from one another, when the jaws are in engagement with one another, a selected calibration distance. The end user of the instrument follows a sequence of steps, including resetting the display unit to read zero and then adjusting and fixing the position of the other jaw to the beam until the selected calibration distance registers on the display unit.
