5On the vernier scale is a small number 0.Look at how many inch divisions it is past

on the bar scale.


6/11

6.

6See how many smaller (numbered) divisions the small 0 has gone past.This

represents how many tenths of an inch the workpiece is measuring in addition to the

number of whole inches.

7How many smaller divisions has the small 0 gone past the last numbered

division, this number multiplied by 25 is how many hundredths of an inch.

8Determine which division line on the vernier scale best lines up with a division on

the bar scale.This is how many thousandths of an inch.

9By adding the inch measurement, the tenths of an inch, the hundredths, and the

thousandths, you will have a measurement to a 3 decimal place accuracy.

Barrel

o The barrel forms the uppermost part of the handle; the part closest to the frame's "U." Thebarrel is a cylindrical piece of metal, integral to the frame; the frame and barrel are molded

as one piece. The barrel's circumference features marks that indicate measurement. Becausethe micrometer caliper measures on a micro scale, its measurements are often lengthydecimals. To save space on the barrel, the marks appear as whole numbers that refer to alegend printed on the frame's exterior.

Thimble

o The thimble refers to the rotating portion of a micrometer's handle. Twisting the thimbleopens the tool's jaws for reading inside dimensions, or extends a rod for measurements ofoutside dimensions or depth. Markings on the thimble rotate along with the handle to align

with the barrel's scale and provide a measurement.

Measuring Rodo The measuring rod, also called the spindle, extends from the thimble. As the operator turns

the thimble, the spindle pushes the object to be measured against the anvil. The spindleholds the object snug against the anvil, and a reading is taken.
