6.2.6.0 Verify the Extensometer

To verify the extensometer in the LCFS test:

1. Click Extensometer Verification in the Low-Cycle Fatigue Strain test.

A message appears: Click the Run button on the control panel to start the extensometer verification.

2. Click the Run button.

The Run button changes color and a message appears: Put the Extensometer in the zero position. Click

OK when ready.

3. Put the extensometer in the zero position and click OK.

4. Click OK.

The Verify Zero Strain Reading window appears. Accept the value or type an offset as necessary.

5. Click OK.

The Strain Full Scale window appears.

6. You may want to set this value to 0.1 and click OK.

The Extensometer Verification Prompt window appears.

7. Click to repeat the extensometer verification or click No to continue.

6.3.0 Run the Test

6.3.1.0 Modulus Check at Start Temperature

You should perform a modulus check before you run a test. The standard template allows you to check the

modulus at start temperature and test temperature (for elevated temperature tests). The start temperature

modulus check helps determine if the system is set up correctly. For example, if you have not pulled the zero

pin from your extensometer, the modulus is incorrect. If you type incorrect specimen dimensions, the modulus

is incorrect.

6.3.2.0 Start Temperature Strain

The Start Temperature Strain button allows you to verify the strain at the start temperature. Enter a value

as necessary and click OK.

6.3.3.0 Measure Modulus

To check the modulus in the LCFS test:

1. Click Measure Modulus.
