The micro-adjuster is a self-contained unit clampable to the carriage of a transfer stand and is provided with a high resolution differential screw. A simple rugged clamp mounted on the micro-adjuster accommodates any suitable test indicator of either the electronic or mechanical type. When used with an electronic indicator, comparative measurements are routinely made to an accuracy of a few millionths of an inch.
