The inside micrometer must be calibrated before each use and after changing rods. The calibration must be done against a known standard, such as an inspection ring. If an inspection ring is not available, a properly calibrated outside micrometer may be used
he unique feature of inside micrometers is their ability not only to measure small diameters and other distances very accurately, but also to measure very large diameters and distances accurately. To this end, inside micrometers may be found in many sizes. There are also sets that include a single measurement head and a number of tubes in varying lengths that can be attached to the head. This type of set can be used to measure a wide variety of inside diameters and various parallel surfaces without the need for multiple micrometers, here are many specialized types of micrometers, but the three most common types are the outside micrometer, the inside micrometer and the depth micrometer. As the names imply, each style of micrometer gauge has its own specific purpose
Reading an inside micrometer is comparable to reading a standard micrometer except that extension rod and collar lengths must be added to the head measurement
