1) Calculate aperture error using the following formula, and check that the aperture error is within the specification.
Aperture error = Average G value of checking lens (b) - Average G value of master lens (a)
Specification:
Aperture error = -18 to 0
2) When the aperture error is out of specification, perform 4-2-2. Aperture Diameter Adjustment .
