right and left lens.
In case that [PD Measure] is [Off], the PD measurement value and measurement area are not displayed.

. Measurement procedure (Right lens > Left lens)
Pull the lens plate toward the examiner.
Place the eyeglass lens so as that the bottom of the frame contacts with the lens plate with the frame
contacting with the left nose pad.
Place the right lens on the lens stand and hold it with the lens holder softly.
Achieve an alignment by moving the right lens back and forth, and right and left with the frame always
contacting with the lens plate.
Store the measurement values and PD measurement values of the right lens by pressing the Memory/ Add
switch after completing alignment.
After the measurement of right lens, place the left lens on the lens stand with the frame contacting with
the right nose pad, and hold the lens with the lens holder softly.
At this time, it is switched from right lens to left lens automatically based on the position of the nose pad.
In a manner similar to (4), achieve an alignment of the left lens. After completing alignment, store the
measurement value of the right lens and PD measurement values by pressing the Memory/ Add switch.
In case that [Auto Memory] on the [Setup] screen is set as [On], the
measurement values are stored automatically after the message [Marking OK]
is displayed.
