1 Measurement (mode)   
A measurement mode is selectable.    Here, select “3-D Time 
scan.”  
For Wavelength scan, Time scan, Photometry and 3-D Scan, refer 
to Sections 2, 3, 4 and 5, respectively.   
2 Operator  
Enter an operator name.   
3 Instrument  
The name of the connected instrument is indicated.

Click this button to read out saved analytical conditions.     
Upon clicking, the file opening window appears.    So, select an 
analytical condition file.   
7 Save  
When you click this button after setting the parameters, the 
analytical conditions can be saved by overwriting.    In case of a 
new analysis method, clicking this button displays the “Save As” 
window.    You must enter a file name for saving in this window.

The window shown below is based on that 3-D Time scan is specified 
for Measurement at the General tab.    When you click the Instrument 
tab, the window in Fig. 6-4 appears.   
For the settable range of each parameter, refer to Appendix G.

1 Scan mode   
Select a scan mode here.    In case of Synchronous, the abscissa 
of the graph stands for excitation wavelength.    The unit indication 
of the abscissa becomes ‘EX/EM (nm).’   
2 Data mode   
Select...

4 EM WL   
For the Excitation scan mode, enter the fixed wavelength on the 
emission side .    For the Synchronous scan mode, enter the start 
wavelength on the emission side.   
5 EX Start WL   
This is the start wavelength on the excitation side in wavelength 
scan.    Enter the shorter wavelength side of measuring wavelength 
range.  
6 EX End WL   
This is the end wavelength on the excitation side in wavelength 
scan.    Enter the longer wavelength side of...

15 Response  
When “Auto” is selected, response will be set automatically 
depending on scan speed.    Select “Auto” usually.   
16 Corrected spectra   
A function for determining the spectrum inherent to a sample by 
correcting the photometer wavelength characteristic using the 
saved instrument parameters, following measurement with the 
instrument parameters for photometer control.    If there are no 
instrument parameters for the wavelength range to be measured, 
only the wavelength...

NOTE:  When the remaining memory capacity of PC in operation is 
very small (system resource is less than 20%), the data 
processing window will not open even if this item is turned ON.   
Either close the presently opened data processing window or 
restart the FL Solutions program.   
 
5 Print report after data acquisition   
Select whether or not to print a report after sample measurement.   
When selected (check mark is applied), printing will be made 
automatically after measurement....
