In order to read a micrometer, you will use the numbers on the thimble and on the sleeve. The numbers on the sleeve are broken down into 4 parts. Think of them as dollars with whole numbers and quarters. The numbers on the thimble can be represented as pennies, or ones. If the sleeve is at 9 3/4 and the thimble is at 4, the reading would be .979.

The maximum reading of a micrometer screw gauge depends on the number of divisions on the thimble and the barrel. Typically, it can measure up to 25 millimeters with a resolution of 0.01 mm on the main scale and an additional fraction of a millimeter based on the thimble divisions.

40 threads per inch. The thimble has 25 divisions. Every 1 turn moves the spindle .025 and .025 x 40 = 1.000 .

Hi, heres how you calculate least count of a micrometer. Use the given formula: Least Count (L. C) = Pitch/no. of divisions on micrometer barrel(thimble) where, Pitch = distance travelled by thimble on linear scale in one rotation. Hi, heres how you calculate least count of a micrometer.

The biggest possible reading on a micrometer screw gauge is determined by the number of divisions on the thimble and the barrel scale. Typically, the main scale has 25 divisions, and if the thimble has 50 divisions, the total maximum reading would then be 25 (main scale) + 50 (thimble) = 75 divisions.

One full revolution of the thimble on a micrometer typically equals the pitch of the thread on the spindle, which is usually 0.5 mm. This means that each full rotation of the thimble will advance the spindle by 0.5 mm.

The total movement indicated on the thimble of a micrometer after one full revolution is equal to the pitch of the micrometer screw. The pitch is the distance that the spindle advances axially in one complete turn of the thimble.

All you need to do is make contact. Tightening will give you a false reading and eventually damage the micrometer.
