Description:
1. Outer diameter measurement: measure the outer size and fit the two measuring surfaces to the surface to be measured
2. Inner diameter measurement: measure the size of the inner hole, the measuring claw should be measured on the diameter of the hole upwards, not skew
3. Depth measurement: To measure the depth, the depth measuring rod should be perpendicular to the bottom surface of the measured object
4. Step measurement: measure the distance of the step. The bottom measuring claw of the step ruler is parallel to the bottom end of the object to be measured, and the top measuring claw is close to the top of the object to be parallel and not skewed
