The depth gauge is used to measure the depth of holes and steps. 8 Height gauge The height gauge could be described as a vernier caliper fixed to a firm base. In contrast to the vernier caliper the height gauge has only one moving anvil connected to a vernier scale. A column having a fixed scale is mounted so that the axis of the column is perpendicular to the reference plane of the base. The motion of the anvil up and down the fixed scale allows vertical distances to be measured accurately. Usually a height gauge is mounted on a surface plate for measurement of vertical distances.
In a least squared design a number of blocks of a set are measured using the comparator and the deviations are determined by multi-linear regression. Details of these procedures are beyond the scope of this book but may be found in the references given in the Bibliography. 5 Calibration of micrometers The calibration of a micrometer consists of testing the instrument for accuracy, flatness of measuring faces and parallelism of measuring faces. 11 Gauge block comparators: (a) mechanical comparator; (b) optical comparator.
However, even in a laboratory with temperature controlled at 20°C, the workpiece 32 Basic Metrology for ISO 9000 Certification temperature may be slightly different. Therefore the temperature of the workpiece is measured using a calibrated thermometer and the dimensional values measured are corrected using the thermal expansion coefficient of the material. 2. When the measuring instrument and the test item being measured are of two different materials a differential expansion results. Corrections are required for these effects.
