Configuration
Modulus: The upper and lower limits of the range for the modulus regression is
defined here as percentages of the peak value. A typical range is 20% to 70%
but these should be altered to accommodate longer or shorter linear regions.
Creep: The number of points for the regressions for Instantaneous Response
and Viscous Response are entered here. Typical values are 5 points and 20
points respectively.
Running a sample in Stand-Alone mode.
Running a one-off test
1. When flashing cursor is on Run Single press OK.
2. Select the measuring system in use
3. Scroll the cursor down to the selected test method: Yield Test or Creep Test.
For Yield Test:
4. Set Rate (rotational rate in rpm), Nr. Of MP (the number of measuring points
to be taken) and Time (the total time of the test).
5. Input any required identification for the data file eg batch number, operator
etc. and press OK
6. Press ST to Start the test.
The display will then show the current and peak values for stress (in Pascals) and
torque (in milliNewtonmetres):
For a Creep Test:
4. Set Stress (the applied stress in Pascals), Nr. Of MP (the number of measuring
points to be taken) and Time (the total time of the test).
5. Input any required identification for the data file eg batch number, operator
etc. and press OK
6. Press ST to Start the test
The display will then show the Angular Position and Instantaneous Angle (in
milliradians), Time (in seconds) and Creep Rate (in milliradians per second):
Stress (Pa): 00000
Peak: 00000
Torque (mNm): 00.00
Peak: 00.00
Angle (mrad): 0000
Inst. Angle: 0000
Time (s): 0000
Rate (mrad/s): 000
