Confi guration
Modulus: The upper and lower limits of the range for the modulus regression is defi ned 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.
D.1.3 Running a Sample in Stand-Alone mode.
Running a one-off test:
When a fl ashing cursor is on Run Single, press the OK key.
Select the measuring system in use.
Scroll the cursor down to the selected test method: Yield Test or Creep Test.
For Yield Test:
Set the Rate (rotational rate in rpm), Number of MP (the number of measuring points to be
taken) and Time (the total time of the test).
Input any required identifi cation for the data fi le, e.g. batch number, operator, etc., and press
the OK key.
Press the ST
key to Start the test.
The display will then show the current and peak values for stress (in Pascals) and torque (in
milliNewtonmetres):
Stress (Pa): 00000
Peak: 00000
Torque (mNm): 00.00
Peak: 00.00
Figure D-1
For a Creep Test:
Set the Stress (the applied stress in Pascals), Number of MP (the number of measuring points
to be taken) and Time (the total time of the test).
Input any required identifi cation for the data fi le, e.g. batch number, operator, etc., and press
the OK key.
Press the ST
key 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):
Angle (mrad): 0000
Inst. Angle: 0000
Time (s): 0000
Rate (mrad/s): 000
