Data Processing - User Sizes
The Data Processing: User Sizes settings allow size banding for the measure-
ment to be defined for all histograms and tables used in reports.
Section/option Description
User sizes A practical use of size bands is when using sieves that con-
form to specific standard sizes - size bands could be set to
corresponding ranges.
The system can either automatically set size bands for histo-
grams and charts, or these can be user-specified.
Use default sizes - Select this check box to automatically
select appropriate high and low sizes based on the measure-
ment result.
Use the sizes that I specify - Select this check box to man-
ually define size bandings. The User sizes (μm) and Gener-
ate user sizes panels become active.
