(5) Repeat this check at 0.500 and 1 inch. The TI should indicate the nominal size
of gage block used 0.0003 inch (with vernier) or 0.001 inch (without vernier).
NOTE
To check micrometer screw properly, all measurements must
be computed from zero indication. Any deviation at zero must
be taken into account at all checkpoints.
b. Adjustments. No adjustments can be made.
