3.4 Absolute Measurements
The 948 and 968 can perform absolute measurement in XYZ (RGB), Yxy,
L*a*b*, L*u*v*, L*C*h°, Whiteness, & Yellowness.
> Helpful Hint: If you are going to measure something like a textile, you will receive
better results if you use the averaging function (see Section 3.6). Also, while measuring
a textile, take several measurements in a circular format.
> If the ∆ is displayed, press [DIF] to activate absolute mode.
> If the desired illuminant/observer is not displayed, refer to Section 3.3.
