Calibration • Page 4-20
IMPORTANT:
Trash tile should be inspected for foreign particles. If
any dust, dirt, lint, or trash is on the tile, it should be
cleaned with a clean dry cloth. DO NOT USE SOAPY
WATER ON THIS TILE. This tile should ONLY be cleaned
with a dry cloth or a lightly damp cloth. Any particles
on this tile may result in a calibration error.
2. Press the NEXT button to continue with calibration.
3. The trash tile will be tested and a pass or fail outcome will be
displayed in the Message window.
4. The measured area and particle count will be displayed in the
Results window.
5. If the particle count is out of tolerance, the rectangle/trash may
need to be adjusted. Check the AUTO-ADJUST RECTANGLE FOR
COUNT MATCHING box at top of dialog box and retry
calibration. Once the count is within tolerance, turn off the auto
adjust rectangle.
6. If the area is out of tolerance, the contrast may need to be
adjusted. The rule of thumb is to increase the contrast to increase
the area.
Note: If the contrast is 100 or above, there may be a problem with
the camera. The fields for contrast and tolerance are located at the
bottom of the
CALIBRATE FLASH AND TRASH screen.
7. When both the area and count are within tolerance, the
calibration will pass. Be sure to click the SAVE CALIBRATION
button to save the results when you are finished.
Note: Once calibration is complete, you can select Print Results.
Note: C ontact an Uster Technologies’ service technician for
assistance if repeated failures occur.
