(3)  The principle of area calculation is shown below. 
 
 
 
 
Fig. 7-34    Principle of Calculation 
 
 
The elements (D
1 to Dn) of a spectrum are subjected to the 
following calculation for obtaining an area value. 
 
S
3 = S1 + S2 = Sa + Sc + Sd 
= {D
2 + D3 + 


 Dn-2 + Dn-1 + (D1 + Dn)/2∗∆λ 
S
2 = Sb + Sd 
= [(D
1 + Dn)∗{∆λ∗ (n – 1)}]/2 
= [(D
1 + Dn)∗{section start wavelength (WL1) –   
section end wavelength (WL
2)}]/2

The result of area calculation can be printed out. 
 
(1)  To print a spectrum and the result of area calculation, put a check 
mark at “Print spectrum.”    (Refer to ① in Fig. 7-35.)  To avoid 
printing a spectrum, remove the check mark. 
 
(2) Click Print to start printing.    (Refer to ② in Fig. 7-35.)   
Upon execution of printing, the Area window will close.     
The same window can be called up by clicking the 
 (area 
calculation) button on the Processing toolbar....

(3)  Upon clicking the OK button after calculation (refer to ③ in Fig. 
7-35), its result is saved although the Area window is closed. 
 
(4)  The result of calculation is reset by clicking the 
 (reset) 
button on the Processing toolbar with the data processing window 
displayed.    Upon calling up the Area window again, therefore, 
“*****” will be indicated in each result box. 
 
NOTE:  Upon execution of file saving after area calculation, its result is 
also saved in a file.    So a...

For expanding the scale in the Area window, use the left button of the 
mouse. 
 
(1)  As shown in Fig. 7-37, specify an area to be expanded by drawing 
a rectangle with the mouse while holding down its left button on a 
spectrum. 
 
 
 
Fig. 7-37 
 
 
(2)  Then release the left button.    The specified area will be 
expanded as shown in Fig. 7-38.

7.13    Transfer of Data to Microsoft(R) Excel 
 
Measured data can be transferred to a worksheet of Microsoft(R) Excel 
in the following procedure. 
 
(1) Click the 
  (properties) button and select the Report tab.     
A tab page as in Fig. 7-39 will open.    Select “Use Microsoft(R) 
Excel” for Output.    Also select data to be transferred (peak table, 
data listing, etc. in case of wavelength scan).    Then click OK.
