de = p X D. (5)
Example: If = 112 pm, = 4.5 mm and D = 100 pm, then d = 4.02 mm.
8. Check the field diameter, D (acceptable range 100 pm ± 2 pm) with a stage micrometer upon receipt of the graticule from the manufacturer. Determine field area (acceptable range 0.00754 mm^ to 0.00817 mm^).
APPENDIX B: COMPARISON OF COUNTING RULES: Figure 2 shows a Walton-Beckett graticule as seen through the microscope. The rules will be discussed as they apply to the labeled objects in the figure.
