Abstract
A measuring system including a linear gauge is placed on a vibration isolation table , and this system assembly is placed in a temperature controllable, constant-temperature chamber. A specimen table , which has a centrally-disposed circular protrusion C of a diameter sufficiently smaller than a specimen under measurement, is mounted on a surface plate of a linear gauge . The position of a measuring element is measured when it is brought into contact with the centrally-disposed circular protrusion C, and the position of the measuring element is measured when it is brought into contact with the specimen placed on the specimen table. The measured values are used to determine the thickness of the specimen.
