9.4 Metamerism

If the metamerism index is set unequal to zero in

“Setup,” the metamerism index will be calculated for

each measurement. If it is larger than the value

selected in “Setup,” it will be indicated by a reversed

“M” in the bottom line of the display.

To display the metamerism index for the individual

illuminants, use the

button to select the “Metamerism” option on the

“Display” menu.

When you press the Operate button, the

metamerism index for the individual illuminants

appears on the display.

The display is determined by the selected

illumination/observer combination. If D65, A, or F2

are selected, the display appears as shown in the

accompanying illustration.

If illumination type C is selected, D65 is replaced by

C. If another fluorescent illumination type (e.g., F7

or F11) is selected, F2 is changed accordingly.

Note:

If the metamerism index is not needed, the limit

should be set to 0.00 in the “Options/Setup/MI

Limit” menu. This reduces processing time and,

consequently, power consumption.
