USING THE INSTRUMENT
6 Follow the similar steps to measure the lens on the opposite side.
Totaled PD will be displayed.
7 Bring the nose rest to the extreme right and fold it. It will stick to the lens table by means of
a magnet.
Range 25~45mm on one side (minimum 0.5mm)
8 Difference may occur by the measurement technique and with low-power lenses having a
large camber angle.
If the measured PD value differs from that of marking PD.
No camber angle A camber angle
Since the optical center of the glasses mounted for
the infinite far is searched, the measured PD value
of CL-300 is called the PD/fitting value.
