IMPORTANT:
The Tile and sample glass must be void of any trash or
other contaminants that could be seen by the camera.
Both can be cleaned with a soft dry cloth or, if
necessary, use a small amount of soapy water. See
IMPORTANT instructions for cleaning trash tile on the
next page.
2. Place the WHITE color tile on the sample window. Make sure the
tile is centered on the window and none of the window is
exposed.
3. Press the NEXT button.
4. The lamps will flash at the rate of one flash about every 5
seconds. An image will be grabbed and analyzed for brightness
and even/odd illumination.
5. Once the flash passes the calibration criteria, the outcome will
appear in the Results window of the CALIBRATE FLASH AND TRASH
screen.
Note: The white tile sets all necessary parameters for the calibration
of the flash.
6. Once the flash has been calibrated, the trash requires
calibration.
Note: Once calibration is complete, you can select Print Results.
