Since the PR-7XX 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 based on chromaticity values only.
