a device used to measure the strain of an object. Thread pitch gauge, also called a threading gauge, pitch gauge, or screw gauge a device used to measure the pitch or lead of screw threads. Vernier height gauge: a measuring device used either for determining the height of something, or for repetitious marking of items to be worked on.
The process will determine the measurement value and uncertainty of the device that is being calibrated (the comparator) and create a traceability link to the measurement standard. [33] The four primary reasons for calibrations are to provide traceability, to ensure that the instrument (or standard) is consistent with other measurements, to ...
