Abstract
A caliper has a pair of arms which are connected for rotation about a pivot point. Each arm has a tip and a contact surface is connected to one of the arms. The caliper includes a mechanical or electronic indicator which is responsive to the relative position of the arms for providing an indication of a dimension, such as the diameter, radius, circumference, or cross-sectional area, of an object. The caliper has an extended range and can provide an indication of the dimension when the tips of the arms and the contact surface simultaneously contact nondiametrically opposed points on the surface of the object.
