 Data List Printing Direction   
The direction of data list printing (with 
constant line spacing) can be set.   
In case of vertical printing:   
Wavelength or time and photometric 
values will be printed vertically in 3 
rows.  
 
 
 
 
 
In case of horizontal printing:   
Wavelength or time and photometric 
values will be printed horizontally in 
3 rows.    That is, 3 data will be 
printed on each line.

1.10  Photometer Menu Commands  
 
The Spectrophotometer menu contains the following commands.   
• Set Wavelength  
• Auto Pre-scan  
• Zero Adjust  
• Shutter Open/Close  
 
Set Wavelength   
This command sets the excitation/emission wavelength to a specified wavelength.   
Click the Set Wavelength command or button, and the dialog box shown below will come up.   
 
 
 
Fig. 1-58   
 
 
Zero Adjust   
This command automatically closes the shutter and measures a zero point in detection.    When the 
zero point is changed, e.g., after variation of the photomultiplier voltage, automatic zero-point 
adjustment will be carried out.   
 
NOTE:  If the lid of sample compartment is opened or closed during zero-
point adjustment, zero point may not be set exactly.    In this case, 
perform zero-point adjustment again. 
 
 
Auto Pre-scan   
This command automatically searches for the optimum excitation/emission wavelength for the sample 
under measurement.    Other peaks than the fluorescence peak (such as peaks of excitation scattered 
light and Raman spectrum) are ignored.    On completion of automatic pre-scanning, the optimum 
excitation/emission wavelength is indicated on the monitor window (in the current wavelength 
indication field detailed in 1.6).   
 
Shutter Open/Close   
This command is available for opening/closing the excitation beam shutter.    The current shutter state 
is indicated on the right side of the monitor window (⑨  in Fig. 1-43).

1.11  Utility Menu Commands  
 
The Utility menu contains the following command.   
• Instrument Response  
•  Analog Output Gain   
•  EX Power Monitor   
• Sensitivity Check  
• Lamp Usage  
• Lamp Off  
 
Instrument Response   
 
This command is used for spectral correction.    The spectral correction accessory kit (P/N 251-0126) 
needs to be prepared.   
 
Analog Output Gain   
 
Use this command for setting a data value corresponding to 1 V of analog output.    For details, refer to 
9.3.  
 
EX Power Monitor   
 
Use this command for checking output of the monitor detector.    When the EX Power Monitor is turned 
on (clicked), monitor value data is displayed regardless of measurement condition.   
 
Sensitivity Check   
 
Use this command for checking sensitivity.    You can check sensitivity/drift with this command.     
For details, refer to the maintenance edition.   
 
Lamp Usage   
 
Use this command for checking/resetting the usage period of the Xenon lamp.    A cumulative turn-on 
time of the Xenon lamp is indicated.   
 
 
 
Fig. 1-59    
						

							1.11 
1 - 45 
When the limit use time is exceeded, the following message appears.   
 
 
 
Fig. 1-60   
 
 
After lamp replacement, reset this indication.    For details, refer to the maintenance edition.   
 
Note:  If the Model F-7000 power supply is turned on without starting up the PC, indication of the 
Xenon lamp turn-on time may not be updated correctly.     
 
Lamp Off   
 
Use this command for turning off the Xenon lamp.   
For turning on the Xenon lamp again, restarting the spectrophotometer is necessary.

1.12    Termination of FL Solutions Program   
 
After completion of measurement, shut down the instrument in the following procedure.   
 
1 From the File menu, select the Exit command.   
A window appears as shown below.   
 
 
 
Fig. 1-61   
 
 
2 For termination without turning off the light source lamp, select “Close the monitor window, but 
keep the lamp operating?”   
For termination after turning off the light source lamp, select “Close (Turn off) the lamp, then close 
the monitor window?”   
Click Yes, and the FL Solutions program will then be terminated.   
3 Turn off the power switch of the spectrophotometer main unit.   
4 Click the start button of Windows XP, select “Turn Off Computer” and click OK.  
5 Turn off power to the personal computer and the CRT display monitor.   
(At step 4, the personal computer may be turned off depending on system settings.)   
6 Turn off power to the printer.
