1. Micrometer Screw Caliper anvilspindle barrel thimble ratchet

2. USING THE MICROMETER SCREW CALIPER 1.Insert the object between the anvil and the spindle. 2.Lock the micrometer screw caliper. 3.Read the linear scale (barrel) in ____ mm. Whole Marks (above): 1, 2, 3, etc. Half Marks (below): 0.5, 1.5, 2.5, 3.5, etc. 4.Read the rotating scale (thimble), divide by 100. 5.Add results of steps 3 and 4.
