Explanation:
A dial indicator is a precision measuring instrument used to measure various factors such as crankshaft end play, crankshaft runout, and valve guide wear. It provides extremely accurate and precise measurements. This tool is commonly used in the field of mechanical engineering to ascertain the roundness of a bore or detect minor imperfections. An object is placed against the probe of the dial indicator, and the gauge records small distances that are too minute to measure with a human eye or other tools, such as a micrometer, dial bore gauge, or a telescopic gauge.
