3.2 Connection/ Wiring
(1) The earth cable of the power code should be connected to the earth terminal.
(2) Avoid damaging the power cord (such as bending it in an extremely small size, pulling,
placing a heavy object on it etc.). Also, do not fabricate the cord.
(3) When the power cord is damaged, (breaks, damage of cover etc.), replace it to the new one.
Fire or electric shock may occur if you keep using it.
(4) Insert the power cord firmly into the outlet and device. If not, fire or electric shock may occur.
(5) Keep the power cord clean without any dust or oil etc. on it. The dirty terminal may cause
malfunction or fire.
(6) When the power cord gets hot after use, check for the dirt of the terminal unit. If you find no
dirt, replace the power cord to the new one. Fire or electric shock may occur if you keep using
it.
(7) Use it with the correct power-supply voltage. Fire or electric shock may occur if using it with
more than the rated supply voltage.
(8) Always hold the plug when plugging or unplugging the power cord.
(9) Do not touch the plug with wet hands. You may get an electric shock.
(10) If the device is not used for a long time, unplug the power cord from the outlet.
3.3 Maintenance/ Inspection
(1) This is the precision optical device. Make sure not to mishandle or
drop it.
(2) Do not touch or allow dust to adhere on the optical parts (i.e.
lenses), as the measurement accuracy could be adversely affected
by fingerprints and dust etc.
When fingerprints or dust are adhered onto the optical parts,
gently wipe them with the accompanying dust cloth or a soft
cloth. In this instance, make sure not to scratch them.
11
(3) If the main unit cover or operation panel is dirty, gently wipe it
with a dry cloth. For hard to remove stains, a damp cloth or
neutral cleanser is recommended.
Avoid using organic solvent such as thinner which
may damage the water based paint finish or device.
(4) If the device is not used for any length of time, unplug the power cord.
(5) When the device is not in use, protect it with the
accompanying dustproof cover. The measurement
accuracy could be affected by dust.
(6) Never attempt to fix or remodel the device. When the
device fails to function properly, do not touch the inside.

•
The lens holder is set properly.
•
The lens under the lens stand is clean.
(In case that the lens is dirty, clean it with
a soft cloth.)
•
Plug the power cord to the outlet.
Always connect the earth terminal to a ground.
•
Set the printer paper in the printer.
(Refer to “5.4.2 Installation and Replacement of Printer Paper”.)
•
Confirm that the lens is not placed on the lens stand.

6.2 Measurement of Single
Single Lens
(1) Place the lens on the lens stand.
Lower the lens holder softly on the lens.
The screen as shown on the right appears.
Do not give strong impact to a lens when lowering the lens holder.
When rising the lens holder, make sure that it is moved to the top and locked.
(2) Bring the cross cursor to the alignment mark by
moving the lens. The message “Alignment
Alignment OK”
OK
appears on the screen when alignment completes.
If the lens is the cylindrical one, rotate the lens to
fit the axis direction.
NOTE
The alignment mark represents the optical center of the lensmeter and the
cross cursor represents the optical center of the lens.
(3) Overlap the cross cursor and the alignment mark by
moving the lens. When they overlap, the message
“Marking
Marking OK”
OK appears to indicate that the marking is
ready to be carried out.
S, C, A and prism are stored in memory by pressing the
Memory/ ADD switch.
The color of the measurement value area is reversed,
and the values are fixed.
※ In case of setting “Auto

.
(3) Perform alignment so as that the bottom of the
framed lens always touches the lens plate in a
manner similar to the single lens.
(4) Save the measurement values in memory by pressing
the Memory/ ADD switch after measurement.
The color of the measurement value area is changed,
and the measurement values are fixed.
NOTE
In case of setting “Auto Memory” on the Setup screen as “On”, the measurement values
are automatically stored in memory after the message “Marking OK” appears.
(5) Switch the lens from right to left and place the lens
in a manner similar to (1).
Switch the measurement to the left lens by
pressing
. At this time, the measurement
values of the right lens remain on the screen.
The measurement of the lens can be started from either right or left.
NOTE

The switch is changed to
, and the progressive
lens measurement screen is displayed by pressing
(single/ progressive lens selection switch).
In case that Auto Prog is set as “On
On”,
On the lens is automatically judged whether the lens is
a progressive lens or not.
Set the lens in the center region of the progressive zone. It starts the auto judgment of the
progressive lens. When the lens is identified as a progressive lens, the screen is switched
to the progressive lens measurement screen. If not, the measurement screen remains as
the single focus lens measurement screen.
When the ADD value is small (less than 1D), the auto detection may not be performed.
Also, if the progressive zone cannot be found at where the lens is set, the auto detection
may not be performed.
In these cases, move the lens back and forth, and right and left slowly.、
When the ADD value is small (less than 1D), the framed lens is small, or the lens is dirty
or has some flaws, the far point and near point may not be detected automatically. In such
case, take a measurement manually.

(3) Measuring procedure of progressive lens (when N.AT is selected for ADD Measure)
1) Detection of progressive zone
First, find the progressive zone by moving the lens back and forth, and right and left slowly.
The cross cursor (screen shown below) appears when the progressive zone is found.
NOTE
Press the Memory/ ADD switch in case that the progressive zone cannot be detected
because ADD value is small etc. It switches to the measurement screen of the far point.
2) Measurement of far point
Take a measurement of far point. Move the lens toward
the device so as that the center of the alignment mark
overlaps with the cross cursor.
The color of the cross cursor is changed to orange by
pressing the Memory/ADD switch after they overlaps.
At this time, the measurement values at far point are
stored in memory.
NOTE
Alignement mark
When “ADD Measure” on the Setup screen is set as “F/N.AT”, it is detected
automatically and the measurement values are stored in memory.
3) Measurement of near point
Take a measurement of near point.
As shown on the right, move the lens slowly to move the
cross cursor (red) according to
.
If it goes out of the progressive zone, the cross cursor moves
right or left. If it goes out of the progressive zone, bring it
back to the zone and move the lens toward near point.
NOTE
Cross cursor
+2 25
Progressive
zone
The cross cursor on the screen indicates the actual
measurement position on the lens. For example, if
it goes to the right side of the lens which is out of
the progressive zone at the time of moving from far
point to near point, the cross cursor is displayed on
the right deviated from the progressive zone.
Perform the alignment carefully when it comes
closer to the near point and
starts blinking.
Once the near point is detected, it blips. The cross
cursor is fixed at the near point and its color
changes to blue. When the near point is attained,
the ADD value is stored in memory automatically.
※Another ADD value (Ad2) can be stored in memory
anywhere by pressing the Memory/ ADD switch after
measurement.
The progressive judgment screen appears again by setting
the lens for the left eye and press
after completing
the measurement.
Take a measurement of the left lens in the same manner
as right lent.
※Measurement can be started from either right or left lens.

Add value (Ad2)
(4) Display of ADD value and assessment graph, and manual operation
(when “Manual” of “ADD Measure” is selected)
When setting “Prog. Graph” as “On” on the Setup screen, the graph is displayed on the
progress lens measurement screen.
Depending on the type of lens, it may be difficult to detect each point automatically even
though normally the near and far points are detected automatically. In such case, take a
measurement manually by reference to the ADD value and assessment graph.
To take a measurement of far point manually, carry out the alignment in the same manner
as the auto measurement.
For the measurement of near point, press the Memory/ ADD switch where the ADD value
is the highest while the alignment cursor stays in the progressive area.
The near point is where the assessment line moves closer to the Y coordinate. Therefore,
carry out alignment by reference to the shape of the graph and blinking of
.
