Use this page to load, save, print, and export data taken with the YR-1 Rheometer. The file name
(including path) of the data currently loaded is displayed at the top of the page.
The test parameters used to collect the data are displayed on the left of the page in the box
labeled “Parameters Used To Collect Data”.
Data is displayed on the right of the page in the box labeled “Data/Results”. All recorded data
points are displayed in the table.
Time Starting at the beginning of the run cycle of the test, data is taken at an
interval equal to the Base Increment parameter. Elapsed time since the
beginning of the run cycle is shown here in units of hours, minutes, sec-
onds, and thousandths of seconds (H:MM:SS.SSS).
% Torque This field displays actual measured % Torque value
Delta % Torque This field displays the difference between the current % Torque value and
the previous % Torque value. As the sample approaches its yield point,
the Delta % Torque should begin to decrease. If the Torque reduction
for the test is 100%, the yield point occurs when Delta % Torque reaches
zero (0).
Stress This field displays the calculated stress for each data point. The final
Stress value (i.e. the Stress at the yield point) is the resultant yield stress.
See Appendix D - Calculations - for the equation used to calculate stress.
Strain This field displays the Apparent Strain placed on the sample for each
data point. The Apparent Strain is the angular distance that the spindle
rotates in the sample. See Appendix D - Calculations - for the equation
used to calculate strain.
The following are displayed in the line immediately below the Data/Results table:
1. The number of the highlighted record
2. The total number of data records
3. The date and time that the highlighted record was taken.
The test results are displayed below that line.
Test Result There are five (5) possible test results:
1. Test Passed
2. Test Failed due to an Under-Range condition
3. Test Failed due to an Over-Range condition
4. Test Failed due to a User-Limit violation
5. Test Failed due to a user cancellation
See Section III.6 - Test Results - for more information regarding these possible results.
