Principle
The testing machine uses a precision digital motor and a digital speed control system as the driving device. After deceleration by the deceleration system, the precision lead screw pair is driven to load to realize the test functions of constant stress, constant strain and constant displacement. The force value data is collected by the High Accuracy Sensor and processed in real time by the full digital closed-loop control system to ensure the smooth transmission and high accuracy.
Applications
Rubber, Plastic film, Braided tape, Packing tape, Wire and cable, Spinning & weaving products, Wire and other metals, Non-metallic, composite tensile strength and elongation testing
Steps
1. Enter the sample parameters and test parameters in advance.
2. Select the test method and install the corresponding fixture.
3. Start the test, and the screen displays the test force, peak value, speed, etc. in real time.
4. Automatically calculate and output the results after the test, and save the data.
5. Return to the initial test position manually or automatically.
Notice
• Make sure that the sample parameters are entered correctly before the test.
• Select the appropriate test method and fixture according to the test object.
• Pay attention to the upper and lower mechanical limits and electrical overload protection functions.
• To avoid overload use, the maximum load value can be set for automatic protection.
• Regularly check the operating status of the equipment to ensure accuracy and safety.
