IDENTIFY DIAL INDICATORS BY TYPE AND CONSTRUCTION
The dial indicator, Figure 40, is a precision measuring instrument. It is
used in machine shops to check size variations of machined parts from the
desired size. It is also used to measure the runout of a flywheel, the end
play of a crankshaft, the lift of a camshaft lobe, the alignment accuracy of
work, and the machine in machine setups.
Dial indicators range in diameter from about 1 inch to 4 1/2 inches. Each
