Abstract
A portable coordinate measurement machine comprises an articulated arm having jointed arm segments. The articulated arm includes an integrated, internal counter-balance in one of its hinge joints. This counter-balance utilizes a coil spring having relatively wide end rings and narrower internal rings machined from a metal cylinder. The spring further includes at least two posts for locking into the hinge structure of the arm as well as a spring adjustment mechanism.
