Manual No. M09-1200-F1016
Details on information that you must enter for each test follow:
a)
Flow Function
The user can set the maximum in consolidation stress to test to, the number of consolidation
stresses to test, whether to space the consolidation stresses evenly or geometrically, the
number of over consolidation stresses to run at each consolidation stress, whether to use
a new sample for each consolidation test, whether to repeat each stress measurement, and
whether to test at the tangent to the Unconfined Mohr Circle.
b)
Time Consolidated Flow Function
The user can set the amount of time to consolidate at each consolidation step, whether
to use a new sample for each time consolidation, the maximum consolidation stress to
test to, the number of consolidation stresses to test, whether to space the consolidation
stresses evenly or geometrically, the number of over consolidation stresses to run at each
consolidation stress, what stress to apply during time consolidation, whether to repeat each
stress measurement, and whether to test at the tangent to the Unconfined Mohr Circle.
c)
Wall Friction
The user can set the material of the wall lid, the maximum stress to test to, the number
of displacement levels to test at, whether to space the displacement levels evenly or in a
doubling progression, the number of stresses to run at each displacement level, what stress
to apply during wall displacements, and whether to use a new sample for each displacement
level.
d)
Bulk Density Curve
The user can set the number of stress setpoints and the maximum stress to test to.

IV.5 Test Execution
To start the test, click the “Run Test” button on the Main Screen. The Lid will descend to a
position slightly above the sample in the Trough; the instrument will perform an autozero; then
the Lid will make contact with the sample and the test begins.
The Raw Data Tab on the Analysis Screen will automatically come up and show the axial
load test data and the torsional load test data. See Figure IV-7 for an example of the raw data
generated during a flow function test. The axial load units are shown on the Y-axis on the left
of the graph (red color) and the torsional load units are shown on the Y-axis on the right of the
graph (blue color). The axes can be changed to the user’s preference by using the drop down
boxes above the graph.
