Abstract: An electronic caliper includes fixed and movable caliper arms mounted on a common housing and having jaws at their free ends. One of the caliper arms is attached to the housing through a pivot pin for pivoting motion between a contact position and a disengaged position. A spring engages the movable arm at a point on a side of the pivot pin opposite the jaws. The spring is under tension so as to bias the contact pad carried by the distal end of the movable caliper arm toward contact with the pad mounted on the distal end of the fixed caliper arm. A non-contact electronic sensor is positioned facing a target disk carried by movable caliper arm at its innermost end within the housing. A plunger, located on the same side of the pivot pin as is the target disk, allows the movable caliper arm to be pivoted to its open position to allow for insertion and removal of the soft tissue to be measured.
