When a surface plate is graded. Over what length is measured when it’s graded?
If a grade B is +/- .0001, is that over 6” or 12” or across the entire plate? I’d guess it’s a standard length, through some searching on the inter webs and the forum I couldn’t really find my answer.
Something that has my curiosity. Thanks for info everyone.
