Clicking the N
ew
button (or selecting New from the File menu) sets all parameters to their default
values.
All open, save, and print operations selected while this page is displayed will open, save, and
print test parameters, but NOT data. The following is a detailed description of the test parameters
involved in creating a yield stress test.
Program Number
This is the number of the memory slot in the DV-III Ultra Rheometer to which the test parameters
will be loaded. There are ten (10) slots, numbered from 0 through 9.
Program Name
This descriptive user-supplied name is loaded into the memory slot in the DV-III Ultra Rheometer
with the test parameters. A maximum of ten (10) alphanumeric characters may be used for this
name.
Spindle
Spindle Number
A two (2) digit code representing the spindle number used for the test must be selected. See Appendix
A for more information regarding spindles for use with the DV-III Ultra Rheometer. Selection of
the appropriate spindle code is important to ensure correct stress calculations.
Immersion Mark
Each vane spindle has two (2) immersion marks. The primary immersion mark is located on the
spindle shaft. Normally, the spindle should be inserted so that the sample reaches this mark. If
the sample container is too small to allow the spindle to be inserted to this mark, the secondary
immersion mark may be used. This mark appears half way down the blades of the vane spindles.
See Appendix D2 for more information regarding spindles and immersion marks.

Note: Selection of the appropriate immersion mark is important to ensure
correct stress calculations.
Pre-Shear Information
An optional Pre-Shear step can be included in the test parameters. If the Pre-Shear box is checked
on the Test Parameter page of the EZ-Yield software, a pre-shear step will be performed before
running the actual test. The user must supply the speed and duration of the pre-shear step. See
Appendix B for a complete list of pre-shear speeds.
