A complete spin of 'drum' will produce an advance of 0.50 mm and the fifty divisions will ‘sweep’ the ‘reference line’. In this way, each division of the drum ‘marks’ the advance of 0.01 mm (one hundredth of a millimeter) of the spindle.
To interact with the micrometer simulation, you can
drag the drum vertically using mouse to rotate drag instrument by dragging other than 'drum' part use mouse wheel or arrow keys to advance the drum adjust zero error from -0.40mm to 0.40mm using slider scale the micrometer to view divisions more clearly using slider
