1. Outline of Adjustments and Calibration of Color Analyzer
Used for Adjustments.
Perform the following adjustments.
1.1 Creating the parameters used for converting the CRT
RGB drive voltage into color temperature coordinates.
This monitor is equipped with a function for copying
color temperature between several monitors.
Because the CRT drive voltage depends on the CRT, the
same color temperature will not be attained amongst sev-
eral monitors even if the same drive voltage has been
supplied.
For this reason, to copy a color temperature between sev-
eral monitors, it is necessary to send the required data
using parameters which do not depend on the CRT such
as the xyY color temperature coordinates.
Select and execute the SYSTEM/COLOR TEMP/FAC-
TORY SET menu on the MAINTENANCE menu. The
D93 color temperature will automatically be adjusted and
at the same time, the drive voltage and color tempera-
ture coordinates conversion parameter will be created.
Use this parameter for copying the color temperature to
other monitors and for copying the color temperature to
the memory card.

1.2 D65/D56 Color Temperature Adjustment
Perform the D56 adjustment only for BVM-14G1U/
14G5U/20G1U.
1.3 Copying Color Temperature Data D65/D93/D56 to Color
Temperature STD, COL1, COL2, AUX
Calibration of Color Analyzer
Generally, to measure the color temperature of a monitor using
several color analyzers, these color analyzers will show dif-
ferent values. The values measured by the color analyzer will
also change with time. For this reason, color analyzers used
for this adjustment should be calibrated first so that they will
show the correct values for the following color temperature
coordinates.
