Tips: inside diameter micrometer vs. outside diameter micrometer?

The difference is that the inside diameter micrometer is to measure the diameter of the inner hole, and the outside diameter micrometer is to measure the diameter of the outer circle, but also can measure the thickness of the inside diameter micrometer for the precision measurement of internal dimensions (divided into monoblock type and connecting rod )

The correct measurement method: inside diameter micrometer in the measurement and its use of the largest size of the rod and its micrometer head connected, in turn, down to the measurement contact, with the inside diameter of the ruler to measure the hole will be measured contact measuring surface support in the measured surface to adjust the differential cylinder so that the differential cylinder side of the measuring surface in the radial section of the hole swing to find the minimum size, and then tighten the set screw to remove and read, there is no tightening screw directly There are also direct readings without tightening the screw.
