BLOS calibration 6.7 BLOS calibration Introduction The calibration must be performed using the Minolta CA 110 / 210 measurement instrument, the calibration cover and the BARCO software tool Mfdcontrol.exe (IMPORTANT- internal use only). You must use the metal calibration cover because it is the only way to ensure that the lens of the Minolta is in the correct position and at the right distance of the panel. The calibration is best performed in a darkened room.
BLOS calibration Remarks: • If the ambient temperature changes, redo the zero calibration The zero calibration can be checked in normal working position by putting the measurement head on a flat surface, so no light will reach the sensor and the display will show 0.00 cd/m². If the zero calibration is not well performed, the message “offset error” will appear or a value greater then zero will be measured. Calibrate the BLOS Nio 2-3-5 MP • Connect the metal calibration cover to the display.
BLOS calibration 34 • Check the Include Backlight check box.

In the main menu, click on I-Guard. 3. In the I-Guard Calibration window, select Monochrome I-Guard. 4. In the Built in Sensor window, read out the Internal Device value. This should be an acceptable value (see the technical specs - Luminance).
Signature check 7.3 Signature check Introduction: This test should be performed after replacing an Interface Board. The Signature Check tests a part of the Video circuit on the Interface Board. To perform the Signature check: 1. Run the software tool Signature test.exe 2. In the menu, select the head and click on the button Measure. The signature check is running now, displaying a number of test patterns. 3. After completion, the software returns if there were errors or not.
Visual checks 7.4 Visual checks Perform the following visual checks: Nio 2-3-5 MP • No scratches on the panel surface or plastics? • No dust particles between the panel and the glass? • When you disconnect the signal cable, does the display go into stand-by? (power LED turns orange) • Check the display quality by displaying some test patterns. A number of useful test patterns are bundled in the software tool Grayscale.exe.
Packaging instructions 8. Packaging instructions Introduction This procedure describes how to pack the display from the service department to another location, e.g., to an MIS service hub. To perform this procedure, be sure to use the original parts from the packaging of the display. To pack the display properly: 1. Take the empty accessory box. 2. If necessary, put the power and signal cables in a plastic bag. Put the cables in the largest compartment of the accessory box. 3.
Packaging instructions 5. If necessary, wrap the power adapter in a plastic bag. Put the adapter in the smallest compartment in the accessory box. 6. Be sure the connector cover is mounted on the display. 7. Push the display in the lowest position. In case of a new type of foot, block its height positioning system by means of the red fixation pin. 8. Put a foam block between the cable guidance wings on the foot. Fix the foam block by means of adhesive tape. 9. Pull a plastic bag over the display.
Packaging instructions Attention: The buffer pieces are not identical. 11. Put the other buffer piece on the other side of the display. 12. Open the cardboard box and turn it 90 degrees. 13. Push a cardboard buffer piece in the cut-away in the foam buffers at the front side of the display. 14. Slide the display into the cardboard box, with its foot going first. Cardboard buffer 15. Put the box upright. 16. Put the T-shaped foam buffer piece behind the display in the box.
Packaging instructions 18. Close the box and tape it.
Troubleshooting 9. Troubleshooting Sometimes if there is a problem, it is not obvious what is the origin of the problem: The Interface board or the LCD panel. There is a relatively easy way to test where lies the cause of the problem. Therefore, replace the interface board by a spare board. This is no problem if you do not perform a calibration. If the problem persists after replacing the board, the cause is the LCD panel. If the problem is solved after replacing the board, the cause is the board.
