Modern micrometer with a reading of 1.639 ± 0.005 mm. Assuming no zero error, this is also the measurement. (One may need to enlarge the image to read it.) Outside, inside, and depth micrometers. The outside micrometer has a unit conversion chart between fractional and decimal inch measurements etched onto the frame
The gauge is then removed and measured with the aid of a micrometer anvil heads, move the head of the gauge around while making the measurement to ensure you get the maximum reading. Grasp the gauge near the head to aid in your maneuvering of the gauge while adjusting the micrometer so it just stops the gauge's motion at one spot only.
There is a relatively short practical scanning range (order of 1000s micrometer) along any direction. The housing is important to shield electromagnetic noise (Faraday cage), acoustic noise (anti-vibrating tables), air flow (air isolation cupboard), and static charge on the sample (ionizing units).

The two basic types with an analogue display are usually easier for the human eyes and brain to interpret, especially if many instrument meters must be read simultaneously. An indicator or needle indicates the measurement on the gauge. The other two types are only displaying digits, which are more complex for humans to read and interpret.

English: Illustration of a micrometer caliper. The micrometer is showing a measurement of 7.145 mm ± 0.005 mm. Legend: Anvil: part that the spindle moves toward, and that the sample rests against; Spindle: moved by the thimble towards the anvil; Ratchet stop: limits applied pressure by slipping at a calibrated torque
The internal works of a mechanical dial indicator are similar to the precision clockworks of a mechanical wristwatch, employing a rack and pinion gear to read the probe position, instead of a pendulum escapement to read time. The side of the indicator probe shaft is cut with teeth to provide the rack gear.
