. Calibration of color analyzer
Generally, when measuring the color temperature of a
certain monitor using several color analyzers, these color
analyzers will show different measured values. The
measured values will also change with time.
Use the color analyzers for this adjustment after calibrat-
ing them so that they will show the correct measured
values at the following chromaticity coordinate.
