General Notes

The “Sieving” – “New Sieving Task” menu item is used to produce a new sieving
task quickly. Initialisations can be set quickly by input a “file name” and all settings
in the sieving task can be determined quickly with a “minimum run”.
Alternatively the menu items can be called up separately:
•
“Options” - “sieving parameters”
definition of the sieving parameters and characteristics
• “Options” - “Edit sieve stack file”
definition of the sieves and storage in a sieve stack file
• “Evaluation” - “table”
setting of the type of tabular presentation of the sieving result
• “Evaluation” - “graph”
setting of the type of representation of the sieving result as a graph
choice of the axes, characteristics, colours, legend etc.
• “Sieve analysis” - “save sieving task”
• Input of comment, name of the sub-directory, name of the results file,
number of the results file
• Input of the material density
• Storage of the sieving task
In addition, the trend analysis settings are transferred into the sieving task.
A sieve stack file is created by left-clicking on the “Save” button in the “Edit sieve
stack file” menu item and entering a file name.
A sieving task is created by calling up the “Sieve analysis” - “Save sieving task”
menu item. There must already be a sieve stack.
The desired sieving parameters and display parameters must be set under the
“Options” - “Sieving Parameters” menu item. The parameters for the evaluation
must be selected in the “Evaluation” - “Table” and ”Evaluation" - “Graph” menu
items.

The measuring results can be evaluated as a graph or table. Characteristics,
which are typical of the whole measurement are presented in a separate window.
The corresponding menu items are “Evaluation” “Table…”, “Evaluation” - “Graph”
and “Evaluation” - “Characteristics…”. The diagram can show several curves (
(maximum of 10).
A trend analysis is conducted to compare several measurements in a series of
measurements. It allows the time-dependent behaviour of some characteristics to
be examined. The “Evaluation” “Mean” menu item allows the mean value of the
sieving results of a maximum 50 measurements belonging to a sieving task to be
calculated and presented.
All evaluation data can be printed and also copied into the clipboard. When the
“File” - “Print Report…” menu item is called up, a log of the sieving measurements
is printed out.
