Displaying Data at Specified Wavelength on Spectra

5.22 Displaying Data at Specified Wavelength on Spectra

This function is usable when you want to compare data at the specified wavelength on two or more spectra.

5.22.1 Display of Data at Specified Wavelength

(1) Display wavelength scan spectra to be compared. For the

operating procedure, refer to 5.10.

(2) Select the Wavelength Data Table command from the View

menu.

Fig. 5-71

The specified wavelength data table is indicated according to the wavelengths set on the Wavelength tab page of the Options window. The Options window is called up by selecting the Options command from the Tools menu. The specified wavelength data table can be output onto a report when a check mark is put at “Wavelength data table” on the Report tab page. The specified wavelengths can be changed in the following two ways.

5.22.2 Change of Specified Wavelength (Options window)

(1) Select the Options command from the Tools menu and click the Wavelength tab. A dialog box as shown in Fig. 5-72 will appear to indicate the presently specified wavelengths.

Fig. 5-72

(2) For changing the wavelength, take the following procedure.

1) Shift the mouse pointer to the wavelength to be

changed and click the mouse.

2) Enter a wavelength.

3) For other wavelengths to be changed, repeat steps 1)

and 2).

For adding a wavelength, take the following procedure.

1) Put a check mark at any wavelength that is not selected (refer to (1) in Fig. 5-73). Up to 12 wavelengths are settable.

2) Move the mouse pointer to the wavelength and click the

mouse.

3) Enter a wavelength (refer to (2) in Fig. 5-73).

To cancel a specified wavelength, remove the check mark from its check box.

(3) After change, click the OK button. The Options window will close and the following message will appear.

Fig. 5-74

Click the OK button. The change on the Wavelength tab page becomes valid at the time of data file loading. So the instrument need not be restarted.

(4) Close the presently displayed data processing windows. Overlaid data can be loaded if saved in a new name.

(5) Redisplay wavelength scan spectra to be compared in the overlay mode. Or load the file saved under a new name in the overlay mode. Select the Wavelength Data Table command from the View menu. A specified wavelength data table is displayed according to the new wavelengths specified on the Wavelength tab page of the Options window.

5.22.3 Change of Specified Wavelength (Spectrum Properties widow)

(1) On the data processing window shown in Fig. 5-71, click the (Properties) button on the Data Process toolbar. The Spectrum Properties window will appear. In this window, click the Wavelength tab. A tab page as shown in Fig. 5-76 will appear to indicate the presently specified wavelengths.

Fig. 5-76

(2) For changing the wavelength, take the following procedure.

1) Shift the mouse pointer to the wavelength to be

changed and click the mouse.

2) Enter a wavelength.

3) For other wavelengths to be changed, repeat steps 1)

and 2).

For adding a wavelength, take the following procedure.

1) Put a check mark at any wavelength that is not selected. Up to 12 wavelengths are settable (refer to (1) in Fig. 5-77).

2) Move the mouse pointer to the wavelength and click the

mouse.

5.22.2

3) Enter a wavelength (refer to (2) in Fig. 5-77).

To delete a wavelength, remove the check mark from its check box.

(3) After change, click the OK or Apply button. A specified wavelength data table will be displayed according to the new wavelengths specified on the Wavelength tab page of the Spectrum Properties window.

NOTE: Information changed on the Wavelength tab page of the Spectrum Properties window is only temporary (not saved in the data file). Upon data loading, therefore, data is displayed according to the setting on the Wavelength tab page of the Options window. When wavelengths for data comparison are determined, set them on the Wavelength tab page of the Options window.
