    5 Manual calibration   
    Put a check mark in this box for creating a calibration curve using 
    factors.    Enter factors in response to the selected calibration type.     
    6 Force curve through zero   
    By putting a check mark in this box, a calibration curve is created 
    so that its factor A
    0 takes 0 automatically.     
    7 Digit after decimal point   
    Set the number of digits below decimal point for indicating the 
    calculated concentration of the measured sample.     
    The concentration value is rounded off to the set number of digits.   
    8 Lower concentration limit/Upper concentration limit   
    This is used to set a normal value range for the concentration of 
    the measured sample.    If the concentration is higher than the 
    upper limit set here, “HIGH” will appear in the Conc column, and if 
    lower than the lower limit set here, “LOW” will appear in the Conc 
    column.

    When you click the Instrument tab, the window in Fig. 4-15 appears.   
    For the settable range of each parameter, refer to Appendix G.

    1 Data mode   
    Select one of the three data modes.    The Luminescence mode is 
    for measuring luminescence in the biological/chemical field.     
    In this mode, only the sample side signal is acquired without 
    performing ratio photometry.     
    2 Chopping speed   
    Select a chopping speed.    Setting is allowed when 
    Phosphorescence is selected for Data mode.     
    The Phosphorescence mode is for acquiring only phosphorescence 
    after extinction of excitation beam while turning a chopper on the 
    excitation side.    An increase in chopping speed makes the 
    chopper turns faster.   
    3 Wavelength mode   
    Selects a wavelength setting for creation of a calibration curve.

    4 Fixed WL 
    When ‘EX WL Fixed’ is selected in Wavelength mode, set the fixed 
    wavelength on the excitation side.   
    When ‘EM WL Fixed’ is selected in Wavelength mode, set the fixed 
    wavelength on the emission side.   
    5 WL (1 to 6)   
    Make your entry for the number of wavelengths specified at the 
    Quantitation tab.   
    6 EX Slit   
    Select a slit width on the excitation side.   
    7 EM Slit   
    Select a slit width on the emission side.   
    8 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.   
    9 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.   
    10 Auto statistic cal. number   
    Calculation is made for mean value, SD (standard deviation) and 
    CV (coefficient of variation).    Set the number of samples for this 
    purpose.  
    11 Replicates  
    Set the number of measurements to be repeated.     
    12 Integration time   
    A function for obtaining data averaged over the specified time for 
    acquisition of stabilized data.   
    13 Delay  
    After pressing the Measure button, measurement is started 
    following the delay time set here.    It is used for stabilization after 
    setting an unknown sample, 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.
