Data processing - Result
The results settings allow you to specify the displayed size range and the type of
distribution that the analysis has used in the measurement.
Section/option Description
Result range Reducing the measurement range is not usually a recom-
mend option, especially when conform to good laboratory
practice. This facility is useful though if a sample includes
two or more distinct size populations which may need to be
monitored individually.
Adjusting the low and high size range will alter the fit
applied to the fundamental result, where the intermediate
values are then read from the curve allowing interpolation of
percentile points. This adjustment will not alter the analysis
bands that are used in the measurement.
