(Green standard record:
Test method of prism
Mold misalignment The accuracy of the body can be verified on a multi-tooth indexing unit, or on a gearbox generator, by a test point dial or by a full combination comparison method. Other methods can also be used. When calibrating, the relative hole is used as the positioning center and the reference surface is used as the positioning surface. 2 Regardless of which of the above-mentioned calibration methods is used, the calibration uncertainty should not exceed the requirements of Table A1 below Table A1
