How to use the point gauge:
When encountering an irregular point, first determine its roughly large point to find almost the same point, and then determine the shape of the irregular point.
Then find the similarly sized rows on the point gauge, and then find the similar shape. Then cover it, if it can be covered, see if its size allows it to pass, if it can, then it can't.
When it is impossible to confirm whether a linear scratch can pass, cover the linear scratch with 25% gray interface.
If the linear scratch cannot be seen and the length of the linear scratch is less than the specified length, it can pass, otherwise it cannot pass.
