3. OPERATING PROCEDURE : Bifocal and Trifocal Lens Measurement
3
When the target changes from
to
(cross), press the read button.
The distance power is locked in.
4
Measure the near add power (Add: 1st add
power).
Pull the lens forward to bring the near portion onto the
nosepiece.
When the add power is detected, the auto add measure-
ment function places the device into add power measure-
ment.
For trifocal lenses, bring the intermediate portion onto the
nosepiece.
5
Press the read button.
The measured data of the near add power (Add) is locked
in.
Because auto read does not function, press the read but-
ton to lock in the measured data.
When the measured prism value is not displayed, “Ad” is
displayed.
• In measurement of the distance portion, auto read works depending on the setting of the Auto read S
or Auto read R/L parameter.
• It is not necessary to align the target.
• Measure the near add power without removing the lens from the nosepiece.
Once the lens is removed, it is necessary to restart from the distance power measurement.
• For trifocal lenses, when the vertical length of the intermediate portion is narrow, the measuring beam
may interrupt the boundary and correct measurement may not be performed.
