The AL200’s default measurement mode is Single Vision, Automatic. This mode is used for fast, easy measurement of a pair of single vision spectacle lenses. The instrument is now ready to measure the right lens, indicated by the highlighted R on the upper left side of the screen.
Centering the lens
Place the spectacles on the lens table and secure the right lens with the lens holder. Using the table base levers and your hand, move the lens until the large cross is positioned directly over the small cross in the middle of the centering target. If the operator inserts a progressive lens in single vision mode, the progressive icon may flash to indicate that the mode should be changed.
Optical Center
When optical center has been located, the AL200 tone will sound and the measurements will be locked on the screen. Upon removal of the lens the AL200 will automatically switch to the left lens, indicated by the highlighted L on the upper right side of the screen. Repeat the measurement process for the left lens. All measurements will remain on the screen until the operator chooses to print or clear the data.

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.

Troubleshooting POWER Screen blank - 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 specifications are shown in the specification table on page 24. MEASUREMENT 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 difficult 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.
