Abstract

A tool for measuring and checking the clamping force exerted by a movable spindle of a length measuring instrument such as a micrometer comprises a housing which is arranged to receive the free end of the spindle when a rim of the housing is placed against a surface of the instrument body around the spindle and the spindle is advanced, a force sensor which is located at the bottom of the housing for engagement by the free end of the spindle, and a read-out device for indicating the force exerted by the spindle as measured by the force sensor.
