1. An ARM processor is adopted, enabling faster sampling and processing speeds.
2. A 7-inch full-color 24-bit touch screen provides an improved human-machine interface. All TG calibration operations can be carried out on the touch screen.
3. The furnace heating system utilizes custom-designed dual-coil nickel-chromium wire winding. This design not only reduces interference but also endows the furnace with higher resistance to high temperatures.
4. A USB communication interface is incorporated, which features high versatility and ensures reliable and uninterrupted communication. Additionally, it supports the auto-recovery connection function.
5. It can automatically switch between two gas flow channels, characterized by rapid switching speed and short stabilization time.
6. Digital flow meters are employed to achieve more precise control of gas flow.

Precautions
1. Temperature and humidity: Ensure the test environment temperature is stable and avoid significant fluctuations. Generally, the room temperature fluctuation should not exceed ±0.5℃.
2. No interference: During testing, ensure there is no obvious air flow, noise or vibration in the test environment.
3. Sample representativeness: Ensure the samples are representative and can reflect the true properties of the material.
4. Sample size and shape: Prepare the samples into appropriate shapes and sizes according to the test requirements, avoiding being too large or too small which may affect the test results.
5. Preheating after startup: After startup, preheat for 30 minutes and wait for the instrument to stabilize before conducting the test.
6. Temperature control: Set the correct temperature range and heating rate to ensure the stability and uniformity of the temperature control system.
7. Stress loading: The dynamic thermomechanical analyzer requires selecting appropriate test frequency to ensure the stability and uniformity of the stress loading system.
8. Data collection and processing: Use the software tools provided by the manufacturer for data collection and analysis, and ensure understanding of how to apply various mathematical functions and evaluation procedures.
9. Safe operation: Follow all safety guidelines, including properly grounding the instrument, using the appropriate power supply, and using protective equipment when necessary.
10. Instrument cleaning: Keep the instrument clean and regularly clean the surface and key components of the instrument to avoid dust and impurities affecting the test results.
11. Regular calibration: Regularly calibrate the instrument's accuracy to ensure the accuracy and reliability of the test results.
12. Dust and moisture prevention: When the equipment is idle, take good measures to prevent dust and moisture.
13. User permission management: If multiple users use the same equipment, use the user permission management software option to set up unique accounts and specific roles for each user to protect data and prevent misoperation.
14. Abnormal situation handling: During the test process, closely monitor the operation status of the instrument and changes in test data to promptly identify problems and take corresponding measures.
