Both standard and digital inside micrometers are available, with both relying on a screwing mechanism to display very accurate readings. Standard micrometers can be read by examining markings on the barrel and thimble of the micrometer, because very small distances are represented by greatly magnified rotationalWhen using the inside micrometer it is necessary to rotate the head end of the micrometer in an axially direction as well as up and down (Figure 4), all the while adjusting the head to the proper feel. Rotating the head in this manner assures that the micrometer is accurately centralized in the part. The inside micrometer, in most cases, is removed from the part while the actual reading is being done. For this reason the barrel lock is relatively snug to retain the reading.
distances as the thimble is turned. Digital micrometers operate in the same way as standard micrometers, but they will have a digital readout on the barrel that negates the need to examine the barrel and thimble for scale and distance markings.
