An ISO 2768-mK mark means the dimension information for which the tolerances are not specified will be followed according to the m and K class. M class is specified in ISO 2768-1 and K class is specified in ISO 2768-2, which including H, K, and L tolerance levels. .1 ISO 200–25600 will be set if Highlight tone priority is set to Enable.2 The maximum limit for ISO Auto can be set to ISO 6400, ISO 12800, H1 (ISO 51200) or H2 (102400).3 According to the settings for Range for ISO Auto, Maximum limit and Minimum limit.4 Maximum limit settable within the range of ISO 400–25600 for ISO Auto in Time.

General ISO Geometrical Tolerances Per. ISO 2768 | The following are general geometrical tolerances per. ISO 2768 for the following: - Linear Dimensions
- External Radius and Chamfer Heights
- Straightness and Flatness
- Perpendicularity
- Symmetry
- Runout
Related Mechanical Tolerance Design Data Variations on dimensions without tolerance values are according to ' ISO 2768'. All tolerance limits are given in mm. ISO 2768 and derivative geometrical tolerance standards are intendedto simplify drawing specifications for mechanical tolerances. ISO 2768 is mainly for parts that are manufactured by way of machining or removal of materials.
