6.1.6

Metamerism warning

The Metameric Index (MI) - DIN 6172 describes the
dependency of the colour diff erence (ΔE) from the
illumination source. This means the colour diff erence
of two objects may look the same in daylight but look
diff erent when illuminated with a diff erent light source
such as fl uorescent light, when the Metameric Index
value is high. This warning limit warns when the
metamerism index is over the variable limit. The MI
is calculated on the diff erence between D65 / A and
D65 / F11. The warning is displayed in the PASS/FAIL
window, with a "FAIL MI!" message. This message
means the sample would normally be within the set
PASS/FAIL limits and only the MI limit is reached.
6.1.7

Standard deviation warning limit

When using multiple scans the standard deviation is
calculated after each scan. The limit can be used to
warn the user that the last scan has a high diff erence
to the value or values previously scanned.
When the warning message is displayed the user can When the warning message is displayed the user can
repeat the last scan by pressing the "LEFT"
The setting of the warning limit should be dependent
on the homogeneity of the sample.
