GGU-ATTERBERG: "Base data" menu item

After selecting this menu item, the following dialog box appears:

Liquid limit can de determined via evaluation to Casagrande or to the falling cone method (60g/60° or 80g/30°). You can specify whether to use the ÖNORM B 4411 designations on the output sheet. By activating the appropriate check box when evaluating the consistency, evaluation can be performed according to the new DIN EN ISO 14688-2.

Select from various standards for plasticity diagram visualisation using the arrow of the
drop-down list.

The DIN EN ISO 14688-2 visualisation is used by default; however, it is also possible to select visualisation according to the requirements of the DIN 18122, DIN 18196 or the ASTM (American Society for Testing and Materials). In addition, visualisation according to the requirements of BS 5930 (British Standard, 1999 edition) is also possible.

Enter the natural water content of the sample, the shrinkage limit and, if available, the oversize grain component and its water content (each in %) into the following four data boxes.

It is also possible to determine the plastic limit using an empirical equation. If this check box is activated, it is not necessary to enter data for the plastic limit. The plastic limit is then determined from the liquid limit by means of the given equation. The equation used should be treated with caution.

If you have determined the plastic limit using a machine, you activate the "Plastic limit determined with machine" check box. Additionally, a machine-dependent corrections "alpha" and "beta" can be entered.
