Group Parameter Description
Display
( continued )
Size Dist. Table Select Yes to display the particle size frequency
distribution table.
Volume Distribution Select Yes to display the particle size distribution
(volumetric conversion distribution) showing both
differential and cumulative. Refer to
Volume
Distribution Graphs, page D-4 for additional
information and examples.
Others Distribution Type The switch of volume distribution conversion is
specified.
Standard uses the standard volume distribution
calculation.
Legacy uses a conventional volume distribution
calculation.
Fitting Range Select an axis fitting range of G2(

) or

.
Use the
applicable min and max fields to specify the range.
G2(

)max

G2(

)min
Enter the upper (max) and lower (min) limits to be
used for calculating the size distribution. The
maximum value allowed is 2; the minimum is 1.003.
(

)max

(

)min
Enter the upper (max) and lower (min) limits to be
used for calculating the size distribution. The
maximum value allowed is 1E+38 (

s); the minimum
is 0 (

s).
Noise threshold (%) Sets the lower limit on the frequency (0 - 100%) of
the peak display in the graph for the particle size
distribution. A peak that is at a lower limit is handled
as noise and is not displayed on the particle size
distribution graph. The default is 0.3% and typically
is sufficient.
Molecular
Weight
Analysis
Constant Fitting Range This constant is used to determine the molecular
weight of the sample. If you select
Yes , alpha (

) and
beta (

) fields are inserted for specifying a range.
The range for the

field is 0.001 to 0.1; for the

field 0.5 to 1.
Refer to Appendix C, page C-1 for a table of
constants and additional information.
