6. Precautions when purchasing
1. Select the appropriate range according to the test material (it is recommended to cover 120% of the expected maximum load)
2. Pay attention to the measurement certification status of the equipment (requires CNAS or CMA qualification)
3. Consider extended functional requirements (such as video extensometer, environmental simulation, etc.)
4. Give priority to models that support multiple international standards
7. Maintenance points
• Monthly sensor zero calibration
• Lubricate the transmission quarterly
• Avoid using it beyond the range (it will damage the force sensor)
• Regularly back up test data (to prevent loss due to system failure)
With the rapid development of materials science, multi-functional tensile testing machines play an increasingly important role in ensuring product quality and promoting technological innovation. Enterprises should choose appropriate equipment models based on their own needs and establish standardized testing procedures to fully leverage their technical value.
