Sample preparation is one of the most important factors in achieving accurate and
reproducible modulus values.
Basic Experimental Steps
1. Choose, install, and calibrate the clamp appropriate for the sample shape and modulus range (see the
Table).
2. Position the thermocouple near the sample.
3. Select the mode of operation (DMA multi-frequency, DMA multi-strain, DMA controlled force, etc)
needed to perform the desired type of experiment.
4. Select the instrument parameters that are specific to the mode chosen (Include frequency or amplitude
tables when appropriate).
5. Create the method that is appropriate to the operating mode, including force, frequency, heating rate
etc. defined by the mode and the clamp type.
6. Mount the properly prepared sample on the DMA. Then start the motor to preview the desired
measurement and confirm that conditions are acceptable before continuing with the experiment.
7. Start the thermal method and perform the experiment.
