4. Operation Modes:
The DMA has the ability to program stress or force, and strain or amplitude in oscillation experiments.
The DMA also allow the following control features:
  - The Stabilization and Data Collection Cycles allow better control of data collection;
  - The Stress/Force Accuracy option allows you to specify how close you need to be to the target stress
    or force. (Applies to the Multi-Stress & Multifrequency-Stress modes);
  - The option Collect Data when Stable allows you to in experiments on samples with rapidly changing
    properties. (Applies to the Multi-Strain & Multifrequency Strain modes);
  - The Go to Temperature option allows the DMA furnace to go to a sub-ambient temperature without
    starting the run so that the clamps can be retightened to better grip the sample after shrinkage.
    Allowable Temperatures: -150°C to 20°C;
  - The Measure after Equilibrate option allows samples to be re-measured after first Equilibrate method
  - The DMA is capable of performing experiments in each of the following modes:
          - Force-Track (Autotension) Modes;
          - Preview Measurement;
          - Temperature Ramp/Single Frequency;
          - Temperature Ramp/Frequency Sweep;
          - Temperature Step & Hold/Frequency Sweep;
          - Constant Temperature, Stress/Strain Sweep;
          - Constant Strain Rate;
          - Isostrain;
          - Creep;
          - Stress Relaxation.
