Meridian 3
4.5 Check Cross talk (s)
Apply Pattern 2. Set contrast and brightness at 100 %.
Measure YA. Then output Pattern 3 and measure YB.
The cross talk value:

4.6 Color Temperature Adjustment
There are three factory preset white color 9300K, 6500K, sRGB.
Apply full white pattern, with brightness in 100 % position and the contrast control at 50 % position.
