Potec PDR-7000 User Manual

PDR-7000 Operation Manual
7.5 Standard Programs
The PDR-7000 has ten programs of Fixed Program(A,B) and User Program(A-H),
which can be programmed by the user.
The following standard programs have already been written in (Fixed) Programs A
and B as factory setting.
○ Fixed Program A
The final prescription is obtained after the monocular full correction (subjective data) is store.
The binocular balance test and auto adjustment are performed in the final field. Then the
precise addition power is measured with the cross grid for near vision in the subjective field.
