This work characterizes a force-balanced piston gauge (FPG), model FPG8601, as a primary pressure standard over its whole operation range from 1 Pa to 15 kPa. To date, FPGs have been handled as secondary standards that are usually calibrated against

A concept for a novel diameter and form measuring instrument is described. The concept utilizes two independent z-axes towers on a common x-axis which each carry their own y-axis and tactile probes. The X- and Z-axes are equipped with metrology frame
