    3 - 6 
    3 EX WL   
    Enter an excitation wavelength.   
    4 EM WL   
    Enter an emission wavelength.   
    5 Time unit   
    Set a time unit.   
    6 Scan time   
    Set a wavelength scan speed.   
    For the relationship between scan time and sampling interval, refer 
    to Appendix H.   
    7 Delay  
    After pressing the Measure button, measurement is started 
    following the delay time set here.    It is used for temperature 
    stabilization, etc.    In repeat measurement, it is the time until the 
    start of the first measurement.    The delay time is invalid for the 
    second and subsequent measurements.   
    8 EX Slit   
    Select a slit width on the excitation side.   
    9 EM Slit   
    Select a slit width on the emission side.   
    10 PMT Voltage   
    A function for controlling the voltage of the photomultiplier detector 
    (photomultiplier tube).    As a reference, changing from 400 V to 
    700 V increases the data value about two digits and changing from 
    700 V to 950 V increases it about 1 digit.   
    When a check mark is put for PMT Voltage 0-1000V, setting is 
    allowed within a range from 0 to 1,000 V.   
    11 PMT Voltage 0-1000V   
    When a check mark is put in this box, the photomultiplier voltage is 
    settable within a range from 0 to 1000 V.   
    12 Response  
    Set a response time.   
    13 Shutter control   
    The shutter can automatically be closed in other than measurement 
    for slowing down sample deterioration due to the energy of 
    excitation beam and opened when measurement starts.      
    						
    							3.2.2 
    3 - 7 
    14 Replicates  
    Set the number of repeat measurements.     
    15 Cycle time   
    Set a repetition interval.   
    16 Stopped Flow   
    When a check mark is put in this box, the stopped flow mode is set.   
    In this case, when you click the measurement start button, the 
    system waits until an external start signal comes in.     
    Then, measurement starts.

    Assign the following parameters.   
     
    1 Y-Axis Max (maximum)   
    Enter a maximum value for Y-axis on the monitor window.   
    2 Y-Axis Min (minimum)   
    Enter a minimum value for Y-axis on the monitor window.   
    3 X-Axis Max (maximum)   
    Enter a maximum value for X-axis on the monitor window.   
    4 X-Axis Min (minimum)   
    Enter a minimum value for X-axis on the monitor window.   
     
    NOTE:  X-Axis Max and Min correspond to a display interval on the 
    monitor window.    For example, when Max and Min are 60 
    and 30, display on the window is made within 30 to 60 s, 60 to 
    90 s, 90 to 120 s and so on.

    5 Open data processing window after data acquisition   
    Select whether or not to conduct data processing after sample 
    measurement.    When selected (check mark is applied), an icon 
    for this function (as shown in 
    ) is displayed.   
     
    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.   
     
    6 Open data processing window after acquisition (Overlay)   
    Select whether or not to conduct data processing with spectra 
    overlaid after sample measurement.    This setting is unavailable in 
    repeat measurement.   
    7 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.    The items set at the Report tab 
    will be printed.     
    8 Overlay  
    Spectra can be overlaid in the monitor window.   
    This setting cannot be selected for repeat measurement.
