Measuring the Average
When taking measurements or setting target colors, more accurate data can be obtained if the averaging
function is used.
The following two averaging functions are available.
• Manual Averaging: When the color of the specimen is not uniform, measurements are performed at
different positions on the specimen and then the average of the measured reflect
-
ance data is calculated. This gives the average data of the entire specimen.
• Auto Averaging: Specified number of measurement are repeated at the same position on the speci-
men and then the average of the measured spectral reflectance data is calculated.
This will improve the accuracy of the measured data.
These two functions can be used in combination. In this case, it is necessary to make settings for both
auto and manual averaging. For details, refer to “Setting a Measurement Condition” (from page E-34).
Note
For average measurement, the average of the measured spectral reflectance data is calculated first, then colori-
metric data is calculated based on that calculated average. Thus, the result may not match the average of colori-
metric data.
Manual Averaging
This method is used when the color of the specimen is not uniform. Measurements are performed at dif-
ferent positions on the specimen and then the average of the measured reflectance data is calculated, to
obtain the average data of the entire specimen.
Set the number of measurements to be performed and the standard deviation, and then start measurement.
Note
Before starting manual averaging, make sure that the number of measurements to be performed and standard
deviation are set. For details, refer to “Setting an Measurement Condition” (from page E-34).
[Setting Procedure]
This operation can be started from a screen in which “BREAK” is displayed.

Make sure that “BREAK” is highlighted, then press A.
Turn B to select “BREAK”,
if it is not highlighted.
• Example when “COND1” is selected.
