Measurement
When using the instrument for long periods of time, the displayed value may change depending on
changes in the environment. Therefore, in order to achieve accurate measurements, we recommend
that white calibration is done regularly using the white calibration plate. White calibration should also
be done before measuring after a long time has passed since the instrument was last used.
White calibration should be done under the same temperature conditions as measurement.
[Operating Procedure]
1
Press the Calibration key while in the measurement screen.
• The white calibration screen appears.
2
Set the calibration data listed on the back of the white calibration plate cover
using the key and the numeric pad.
•
The cursor moves automatically to the next position when setting data using the numeric pad.
• Use the to move the cursor to make corrections.
• Go to step 3, if white calibration data has already been set.
[Example]
• Illuminants C Y=93.5 x=0.3114 y=0.3190
• Illuminants D65 Y=93.5 x=0.3140 y=0.3318
