..... On calibration of the color analyzer
When color temperature of any monitor is measured by
two or more color analyzers, these color analyzers show
different measurement values even though the object of
measurement is the same. Also the measurement value
of color analyzer changes as time elapses.
Therefore, any color analyzer must be calibrated so that
it shows the correct measurement value of the following
chromaticity coordinate before using the analyzer.
