The area correction function enable measurement data to activate the correction factor
automatically at preset area in chromaticity diagram when measured chromaticity value enter the
preset area. The area can be specified up to 5 areas at once. For example, when you intend to
measure the luminance and chromaticity of R (red), G (green), B (blue), and W (white) color with
each correction factor applied, once you preset correction factor and area data for each of colors,
it is not necessary to change the setting of correction factor at each color measurement.
It is possible to specify up to a maximum of 5 areas. Also, the minimum luminance value is set.

The range of chromaticity area is depend on actual measurement values, and
small errors may occur. Depending on the situation, leeway should be set for
the range.
The method for specifying a chromaticity area is as described below.
