Inter- Adjustment SOmm Or less | set the observation state, insert
pupillary range at minimum a thin paper with graduations at
distance 76mm or more | the eye point position and measure
adjustment at maximum the interpupillary distance.
Working 1000 ~ 2000g Tie a string around the sleeve
force periphery and measure the
interpupillary distance working force
with a tension gauge.
Diopter Adjustment +5 diopters Turn the diopter ring and check
difference range min. that the scale goes over the limit.
