A feeler gauge is an instrument used to measure gap widths between two flat surfaces where it is difficult to reach. It is found in the metrology section. Feeler gauge consists of small steel lengths (leaves or blades) of different thicknesses with measurements label…

Various specific terms describe the characteristics and quality of measuring instruments, which are defined as follows: Accuracy: The degree of agreement of the measured dimension with its true magnitude. Amplification: The ratio of measuring instrument output …

There is a wide variety of g eometries that are measured in angular units . These varieties include the angular separation of bounding planes, digression from a basic direction, angular spacing conditions related to a circle, etc. Because of these diverse geometrical f…
