  Measuring Accuracy
  ... performed in the same manner throughout the world (Fig. 52). In cases where processes are to be controlled only internally, observation of the repeatability alone often proves sufficient. The aspects specified above will be covered in more detail in the following sections.

  Measuring Uncertainty
  ... company standards and has been introduced under the term “Measurement System Capability”. Through representative measurements, both the repeatability and the traceability of the measurement to individual externally cali- brated components are checked. The repeatability of the measurement is checked by continuously measuring different parts of the same type (representatives of a typical manufacturing process) ...

  ... is simply to change the lens. This can be done automatically (for example, with a revolving lens changer). The main problem here is the high repeatability required for a lens change. This approach thus has a negative effect on the measuring uncertainty. Since only two different magnifications are ... be expected. However, such losses should be negligible in modern systems. Linear guides are used in the Werth Zoom to ensure high positioning

  Specification and Acceptance Test
  ... and the length measuring error. The inspection of the probing error has the purpose of characterizing the behavior of the sensors used and the repeatability of a measurement. This is done by measuring a calibrated sphere with a specified number of probing points and then determining a limiting value ...
