　　1、 Equipment preparation and inspection

Before using the power cord tension torsion testing machine, a comprehensive inspection should be conducted first:

1. Check the power supply: Confirm that the power connection of the device is normal and ensure that the voltage is consistent with the device requirements.

2. Check mechanical components: Check whether the tension and torsion parts are running smoothly, ensuring that there is no looseness or abnormal wear.

3. Check sensors: Ensure that the calibration of force sensors, angle sensors, and other equipment is working properly for accurate and reliable test results.

4. Confirm fixture and sample installation: Install appropriate fixtures according to the test requirements to ensure that the power cord is securely fixed.

　　2、 Equipment settings

1. Select test mode: Choose the tensile test, torsion test, or combined tensile and torsion test mode as needed.

2. Set tension and torsion parameters: Set appropriate tension and torsion angles based on the specifications and standards of the power cord. Common parameter settings include tension value, torsion angle, and torsion frequency.

3. Set the test speed: Adjust the testing speed for tension and torsion according to the test requirements. Generally, the speed for tension testing is slower, while the speed for torsion testing is faster.

　　3、 Operation steps

1. Sample installation: Fix one end of the power cord to be tested in the tension fixture and the other end in the torsion fixture, ensuring that both ends of the power cord can be firmly fixed without loosening.

2. Start the equipment: Start the testing machine and observe whether the equipment starts smoothly, ensuring that all mechanical actions are normal.

3. Start testing: Based on the set parameters, initiate the experiment and observe the operation of the equipment. During the testing process, tensile and torsional forces are gradually applied to the power cord, and the equipment will record and analyze the data.

4. Monitoring the testing process: During the testing process, continuously observe the working status of the equipment and pay attention to whether there are any abnormal sounds or vibrations. If any problems are found, the testing should be stopped immediately and checked.

　　4、 Processing and analysis of test data

After the test is completed, the device will generate relevant test data reports, which include various performance indicators of the power cord under tension and torsion, such as tension, torque, number of twists, and the damage of the sample. Based on these data, evaluate the strength and durability of the power cord to determine if it meets the standard requirements.

　　5、 Equipment maintenance and upkeep

1. Cleaning equipment: After use, clean the surface of the equipment in a timely manner to avoid dust and dirt affecting the normal operation of the equipment.

2. Regular calibration: Regularly calibrate the force and angle sensors to ensure the accuracy of the test results.

3. Check lubrication: Regularly check the lubrication of mechanical components to avoid equipment failure caused by excessive wear.

By operating the power cord tension and torsion testing machine correctly, not only can the accuracy and reliability of the test be ensured, but the service life of the equipment can also be extended, ensuring that the power cord products meet quality standards and meet practical application needs.
