Average Measurement
When taking measurements or setting target colors, more accurate data can be obtained if the averaging
function is used.
With the CM-700d/600d, 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 spectral
reflectance data is calculated. This gives the average data of the entire specimen.
• Auto Averaging : The specified number of measurements are repeated at the same position on the
specimen 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 also be used in combination. In this case, it is necessary to make settings for
both auto and manual averaging. For details, refer to page E-45 “Auto Averaging (Auto Ave.)” and page
E-46 “Manual Averaging (Manual Ave.)”.
Note
For average measurement, the average of the measured spectral reflectance data is calculated first, then
colorimetric data is calculated based on that calculated average. Thus, the result may not match the average of
the measured colorimetric data.
Manual Averaging
This method is used 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 spectral reflectance data is
calculated, to obtain the average data of the entire specimen.
Note
Before using manual averaging, you must complete the settings for manual averaging.
For details, refer to page E-46 “Manual Averaging (Manual Ave.)”.
