IV.7.1 How to Save Data
Once the test has completed, you have the choice to save the raw test data and/or the calculated
stress data (click on the Stress Data Tab). Most users will choose to save only the calculated
stress data, since this is the basis for computing the desired output parameters: flow function,
friction angle curves, density curve and critical hopper dimensions.
The raw test data consists of 50 data points per second, which means that the file size can be
large, especially for tests of lengthy duration. For this reason, most users may choose not to
save raw data.
To save the calculated stress data, click the disk icon on the toolbar. To save the raw data, click
the box called “Save Raw Data” located next to the disk icon, then click the disk icon; this will
save both the raw data and the calculated stress data.
The graph may be saved separately as a bitmap by clicking the disc icon above the selected graph.
To get the desired picture, the buttons above the graphs can be used to zoom in, zoom out, as well
as scroll the axis. Right clicking on the axis gives the option “zoom to fit” which can be a very
useful tool (for example, instead of saving the huge raw data file, the user can use the “zoom to
fit” feature to fit the entire raw data sequence and then save it as a bitmap instead.).
IV.7.2 Choices for Data Display
Figure IV-13 shows the available choices for data that can be displayed (Raw Data, Stress Data,
Flow Function, Friction Angle, Density, Hopper Design) and the format for displaying the data
(Graph, Results, Data). Click on the boxes that you require and the corresponding data and/or
graph(s) will be shown.
Figure IV-13: Options for Data Output Display
When the test for Bulk Density Curve is selected, the tabs which appear include Raw Data,
Stress Data, and Density.
Note that the different results are available depending on the type of test that was run. The Flow
Function tab applies only to Flow Function and Time Consolidated Flow Function tests. Bulk
Density tests include only Raw Data, Stress Data and Density.
