3.2.4 Correction Factor
Measurement results can be corrected by applying the correction factor on the measurement result.
"Correction factor" is a function for correcting measurement results according to an internal
program.
Correction factors can be registered in the following 3 ways:
1 By directly entering KX, KY, KZ
2 By entering luminance chromaticity and performing measurement to obtain KX, KY, KZ
3 By connecting to another instrument and comparing measurement results to obtain KX,
KY, KZ(direct correction)
Measurement results are corrected according to the following formula:
X ’ ＝
X × KX
Y ’
＝
Y × KY
Z ’ ＝
Z × KZ
where, X',Y',Z' : Tristimulus values after correction
X ' ,Y ' ,Z ' : Tristimulus values obtained by measurement
KX,KY,KZ : Correction factor for tristimulus values

Select the correction factor group from FACTOR A/B.
FACTOR A : The correction factors obtained by direct entry of correction factors KX,
KY, KZ above or by entry and measurement of luminance chromaticity
are stored in this group.
Up to 10 correction factors can be stored in this group.
FACTOR B : The correction factors obtained by direct correction are stored in this
group.
Up to 5 correction factors can be stored in this group.
