1. It adopts a 7-inch touch screen for more convenient operation.
2. Data collection uses load cells to accurately collect stress change data.
3. Two operation series are available, and you can switch between automatic and manual modes at will.
4. Professional PC software analysis system provides a more intuitive display of various data graphs.

Precautions:
1. Equipment inspection: Check if the appearance of the instrument is intact, if all components are present, and if functions such as power supply and display screen are normal.
2. Calibration of the instrument: Perform calibration operations, using standard samples or samples with known density to verify the accuracy of the instrument.
3. Sample preparation: Take an appropriate amount of uniform, dry, and impurity-free samples. If necessary, conduct pre-treatment such as sieving to ensure the representativeness of the samples.
4. Clean the sample area: Clean the parts of the instrument that come into contact with the samples to avoid residues affecting the measurement results.
5. Correct placement of samples: Place the samples in the measurement area. When filling the samples, avoid overfilling and ensure the surface is flat.
6. Reasonable parameter setting: Set parameters such as pressure and time according to the type of sample and requirements. Different materials may require adjustment to suitable conditions.
7. Safe operation: Wear necessary safety protection equipment such as gloves and goggles during operation to avoid contact with high-pressure areas.
8. Multiple measurements: Conduct multiple measurements on the same sample and take the average value to reduce random errors and improve data reliability.
9. Data analysis: Organize and record the data, calculate the average compacted density of the sample, and determine if it meets the requirements.
10. Instrument cleaning: Turn off the power, clean the instrument, especially the parts that come into contact with the samples, to avoid residues affecting the next measurement.
11. Storage environment: Store the instrument in a dry, well-ventilated environment with suitable temperature and humidity to avoid adverse effects such as moisture, high temperature, and high humidity.
12. Regular maintenance: Regularly maintain and service the instrument, such as calibration, checking battery power, and replacing damaged components.
13. Clean the mold: After use, promptly clean the residual powder inside the mold, check the wear of each component, and replace damaged parts in a timely manner.
14. Safety regulations: Be familiar with and abide by safety regulations, ensure that the emergency stop device is in good condition, and avoid arbitrarily changing instrument settings.
