Prism Measurement
Marked Lens
Prism measurements for a marked lens are obtained by measuring at the indicated
measurement point on the lens.
Unmarked Lens
Prism measurements in an unmarked lens are obtained by:
• First applying a non-permanent ink dot on the lens where the patient’s distance
vision is focused (aligned with the center of the pupil). If an add segment is present,
a second dot may be applied to facilitate the add reading
• Prism (and Sphere, Cylinder, and Axis) measurements are obtained by measuring
at the ink dot on the lens.
NOTE: Measurements for prism are displayed in either the x-y (x, y displacement in
mm), or P-b (prism in diopters) as indicated in the SETUP mode (Prism option).
NOTE: If a lens is not marked with the optical center, an inaccurate prism
measurement may be displayed.

Obstruction Viewer
The AL200’s obstruction viewer is a real-time view of the camera image inside the
instrument. See picture below.
The obstruction viewer is particularly helpful in identifying obstructions that could affect the measurements of a lens, such as excessive dirt or markings on the lens.
The obstruction viewer also assists with viewing the rim of a lens while measuring
progressive lenses, as well as viewing the line on a bifocal lens.
The obstruction viewer is always on the screen and there is no need to adjust any
settings.

- Instrument may be in sleep mode - push any button.
- LCD contrast may be set incorrectly.
Adjust knob on the back of the AL200.
Instrument will not turn on
- Ensure power cord is properly seated in the power input
receptacle on the back of the AL200. Ensure that the instrument is plugged into a wall outlet of the correct voltage.
- Check the fuses located in the fuse holder on the back of the
AL200. Replace fuses if required. Fuse speciications are

Data on screen with no lens in place
- There may be dirt inside the aperture.
Refer to page 23 for cleaning instructions.
Unstable / erroneous readings
- Instrument may have been turned on with a lens in place,
causing improper calibration. Remove all lenses from AL200
and reboot the instrument.
- There may be dirt inside the aperture.
Refer to page 23 for cleaning instructions.
Obstruction detected message
- Ensure that there are no physical obstructions in front of the
aperture.
NOTE: if the marking pens are not fully returned to their resting position they may obstruct the aperture.
- There may be dirt inside the aperture.
Refer to page 23 for cleaning instructions.
Lens positioning is abnormally slow
- Dark lenses are more dificult to read and may cause
positioning to be slower than normal.
- There may be dirt inside the aperture.
Refer to page 23 for cleaning instructions.
- The lens being measured is dirty or scratched. Cleaning the
lens may help.

period of one year from the date of invoice to the original purchaser. (An authorized dealer shall not be considered an original purchaser.) Under this warranty, Reichert’s sole obligation is to repair or replace the defective part
or product at Reichert’s discretion.
This warranty applies to new products and does not apply to a product that has been tampered with, altered in
any way, misused, damaged by accident or negligence, or which has had the serial number removed, altered or

Lamps, bulbs, charts, cards and other expendable items are not covered by this warranty.
All claims under this warranty must be in writing and directed to the Reichert factory, Technical Service Center,
or authorized instrument dealer making the original sale and must be accompanied by a copy of the purchaser’s

This warranty is in lieu of all other warranties implied or expressed. All implied warranties of merchantability or
itness for a particular use are hereby disclaimed. No representative or other person is authorized to make any

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 iled 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.
