2.7. Selection of measurement data

[

] button
The radio button located to the left of the Measure button is a data selection button. It
indicates whether or not data is currently selected.
2.8. Deletion of measured data

[Data Clear] button
Clears the data currently selected.

[All Clear] button
Clears all the measured data.
2.9. To find the reflectance for each wavelength
When any of the
[<<][<][>][>>]
buttons on the cursor panel at the lower right is pressed, the
cursor moves over the graph of spectral reflectance data, and the wavelength [nm] and
[Reflectance [%] of the position where the cursor is located are indicated. [See "3.4 Cursor
panel" in Section 3.]
2.10. How to find the chromaticity coordinates (440nm - 840nm excluded)
Simultaneously with the measurement of spectral reflectance data, USPM-RU Ver.3.21
calculates the corresponding chromaticity coordinates on the chromaticity diagram panel,
shows the numeric values of the coordinates, and indicates the position on the chromaticity
diagram with the cursor. Moreover, the software displays the hue angle, chroma, mean
reflectance, and luminous reflectance. The field and the type of light source currently selected
are also indicated on the chromaticity diagram panel. [See "3.2 Chromaticity diagram panel" in
Section 3.]
2.11. How to calculate color difference (440nm - 840nm excluded)
Click [Color difference] of the [Analyze] menu.
Select any two data points in the color difference measurement window, and click the
[Calculation] button. Then, the result will be displayed. [See "8.4 [Color difference
measurement] menu" in Section 8.]
2.12. How to save spectral reflectance data
