Dimensions

Dial caliper is a very handy and convenient dimension measuring tool. It can measure outer diameter, inner diameter, thickness, Step and depth.Steps for using a caliper: 1. Clean the panel before measurement..2. Close the jaws and check that the indicator points to "0" on the dial face.If caliper doesn't zero, loosen the bezel clamp screw and rotate the bezel to the "0" position.Tighten the bezel clamp screw to fix the "0" position. 3. Dial graduation of .001" and .100" in one revolution for dial caliper of inch system. 4. Dial graduation of 0.02mm or 0.01mm and 2mm or 1mm in one revolution for dial caliper of metric system.5. Clean the panel after measurement.

Thimble-      The thimble rotates around a cylinder which is marked in millimeters-      The left-hand side of the thimble has markings all around it-      The line labeled 0 is the primary pointer.Close the jawsCalculate the least countPlace the object between the two jaws (Anvil andspindle), Spin ratchet until you hear 3 clicks.Record the position of main scale where the twomeasuring rods metNote the position of the circular scale whichcoincides with main scale.
