FIGURE 59 - Y XY DATA ENTRY SCREEN
Since the PR-655 / PR-670 measures the spectral content of the sample, it is possible for the instrument to
calibrate the display white point based on user entered values for luminance and CIE chromaticity. The user can
select to enter
Y x,y
(luminance and CIE 1931 X, y values) or
x,y.
If
Y x,y
is selected, after calibration of the
display, the luminance is properly adjusted to the entered value for
Y
. If
x,y
is chosen, the absolute luminance
value is ignored and the display is calibrated to chromaticity values only.
