Instructions For Use(continued)
Measuring Prism Power
Prism power is indicated by the position of the center
of the target with respect to the Eyepiece reticle.
The innermost Prism Ring is 1 prism diopter, the
second Prism Ring is 2 prism diopters, and the third
Prism Ring is 3 prism diopters. Refer to Figure IU-06.
Note: The innermost tips of the scale lines
indicates 1/2 prism diopter.
Place a dot on the lens at the “optical center”1. position (the point at which the prismatic power
is to be measured).
Place the lens in the instrument with the dot in2. the center of the Lens Holder and the 180° line
parallel to the Lens Table.
Bring the target into focus.3.
Note: The target will not be centered on the reticle
if there is prism power. The target will
always be decentered in the direction of
the base of the prism. For example, if the
center of the target is above the center of
the reticle, base up prism is indicated.
Rotate the Prism Scale until the line of the scale4. passes through the center of the target. Refer
to Figure IU-07.
Note: The amount of prism power is indicated by
the displacement of the target center with
reference to the concentric circles of the
reticle.
Note: Powers of 1.00 to 4.00 prism diopters are
clearly indicated with numerical designations.
Small cross-lines on the Prism Scale indicate
1.5 prism diopters and 5 prism diopters at the
extreme ends of the Prism Scale.
Note: Figure IU-07 indicates a prism power of 3
diopters at an axis of 35°.
If the center of the target is below the center of5. the Eyepiece scale, add 180° to the axis scale
reading.
When measuring prism powers above 5.06. diopters, the Prism Compensator is used to
bring the center of the target into the center of
the Eyepiece scale.
The prism power and axis is then read from the7. Compensator Scales.

CLAIMS FOR SHORTAGES
We use extreme care in selection, checking, rechecking and packing to eliminate the possibility of error. If any
shipping errors are discovered:
1. Carefully go through the packing materials to be sure nothing was
inadvertently overlooked when the unit was unpacked.
2. Call the dealer you purchased the product from and report the
shortage. The materials are packed at the factory and none
should be missing if the box has never been opened.
3. Claimsmustbeledwithin30daysofpurchase.
CLAIMS FOR DAMAGES IN TRANSIT
Our shipping responsibility ceases with the safe delivery in good condition to the transportation company.
Claims for loss or damage in transit should be made promptly and directly to the transportation company.
If, upon delivery, the outside of the packing case shows evidence of rough handling or damage, the
transportation company’s agent should be requested to make a “Received in Bad Order” notation on the
delivery receipt. If within 48 hours of delivery, concealed damage is noted upon unpacking the shipment and
no exterior evidence of rough handling is apparent, the transportation company should be requested to make
out a “Bad Order” report. This procedure is necessary in order for the dealer to maintain the right of recovery
from the carrier.
