Self Calibration - NEC MD21GS-3MP Installation & Maintenance Manual

Self Calibration

Use GammaComp MD Quality Control Software for history management (Constancy test).
performed, display should warm-up for a minimum 30 minutes. If the USB sensor is plugged in before the minute warm-up,
a warning will appear on-screen (Figure S.3). NOTE: Stand-alone calibration can only be performed using the
GretagMacbeth Eye-One Display Sensor.

1. Plug-in the USB sensor to the USB sensor port (Figure S.1).
NOTE: USB sensor port can only be used for the sensor connection.
2. The calibration menu will open automatically and the sensor will begin to initialize. After initializing, the DARK-
MEASUREMENT message is displayed. If the DARK-MEASUREMENT message is not displayed, please proceed to step 5.
3. Place the USB sensor face down on a non-reflective, opaque surface (ie...desk or a mousepad) to measure the black
level (Figure S.2). Press "SELECT".
4. After the DARK-MEASUREMENT has succeeded (Figure S.4), press "SELECT" to continue. If DARK-MEASUREMENT fails
(Figure S.5), restart the calibration procedure.
5. Use "+" or "–" to select SELF in the MODE selection (Figure S.6). Press "<" or ">" to move to the next selection. Use "+" or "–"
to select DEFAULT or COPIED WHITE in the WHITE selection (Figure S.6). Press "<" or ">" to move the next selection.
6. Select the target GAMMA: NO CORRECTION, DICOM, LOG LINEAR, PROGRAMMABLE, CUSTOM, and SKIP (Figure S.6).
NOTE: If CUSTOM is selected, the Gamma Value can be manually changed in intervals of 0.1 at 0.5-4.0. If SKIP is
selected, the GAMMA calibration is bypassed reducing calibration time.
7. The procedure will ask for the USB sensor to be placed on the center of the display panel (Figure S.7). Tilt the display
panel approximately 5˚ backward and place the USB sensor in the center of the display panel (Figure S.1).
NOTE: Place the USB sensor flat against the LCD to avoid external light contamination. DO NOT press the calibrator
against the display panel. Press "SELECT".
8. Set the target LUMINANCE (cd/m
