ABSTRACT:
A measuring machine (100) having a movable horizontal arm (130) and a vertical column (120) for mounting a probe (140) with respect to a table (110), the arm and column each including means for measuring relative displacement of the arm. The measuring means for the arm or column includes a scale (200, 400) and a vernier (300, 500) (one fixed and one movable with the arm or column), wherein the scales for the horizontal arm and the vertical column are substantially identical and interchangeable and include reference numerals (220, 420) which are positioned at an incline (or acute angle) of approximately 45 degrees with respect to the length of the scales and the arm movement. Lead lines (230, 430) having a similarly angled or inclined portion extend from adjacent each reference numeral toward a measurement division indicator (measurement indicia) (210, 410).
