GGU-SIEVE: Preface
The GGU-SIEVE program system allows evaluation and presentation of (combined) sieve and hydrometer analyses according to DIN EN ISO 17892-4:2017-04. The soil type can be determined according to DIN 4022, DIN EN ISO 14688-1 or ASTM.
10 tests can be edited and presented simultaneously by the program. Notes and the results of these ten tests are presented in a table on the output form (diagram table). It is necessary to restrict the table to ten tests for space reasons; more tests will not fit in the table.
Input of further 100 tests is possible with the "Special" menu. For these tests (to be called extra grain size distributions or extra GSDs), no entry in the table is made. Only a legend will be shown, making possible an allocation of line type and test designation. Using the extra GSDs, it is also possible to define boundary curves. Further to this, hatching can be created to enhance the boundary areas.
The program includes convenient data input. The system is permanently displayed on the screen. Every change to the data is displayed on the screen, so that optimum control of the input data is guaranteed.
There are "?" and "Info"’ buttons in the dialog boxes for many technical and program-specific questions. Click on the "?" buttons or "Info" buttons to obtain the necessary information.
The graphic output supports the true type fonts provided by WINDOWS, so that an excellent layout is guaranteed. Colour output and numerous graphic formats (BMP, TIF, JPG etc.) are supported. PDF and DXF files can also be imported via the integrated Mini-CAD system (see "Mini-CAD" manual).
The program has been extensively tested. No errors have been found. Nevertheless, liability for completeness and correctness of the program and the manual, and for any damage resulting from incompleteness or incorrectness, cannot be accepted.
