How to calibrate the spring tensile testing machine?

Spring tensile testing machine is an experimental equipment used to test the tensile and compressive properties of materials. The method of calibrating the spring tensile testing machine can be carried out according to the following steps: 1. Prepare tools and materials: spring tensile testing machine, standard weight, percentage meter, electronic balance, wire rope, bracket, height-adjustable bracket, test sample. 2. Place the spring tensile testing machine on a flat ground and adjust the height of the testing machine so that the center of the test sample coincides with the center of the testing machine. 3. Hang the standard weight on the testing machine and adjust the weight so that the reading of the testing machine is consistent with the weight. 4. Place the test sample on the testing machine, and adjust the height and position of the test sample so that the center of the test sample coincides with the center of the testing machine. 5. Use a percentage table to measure the diameter and height of the tested sample, and calculate the cross-sectional area of the tested sample.6. Use an electronic balance to measure the mass of the tested sample. 7. Set the experimental parameters according to the experimental requirements, start the experiment, and record the experimental data. 8. Process the data according to the experimental data and calculate the tensile strength and compressive strength of the material. 9. Clean up the site after completing the calibration. The following points need to be noted during the calibration process: 1. During the calibration process, it is necessary to maintain a stable ambient temperature and humidity to avoid the impact of external interference on the experimental results. 2. The equipment needs to be checked and maintained before the experiment to ensure the normal operation of the equipment. 3. During the experiment, it is necessary to follow the operating procedures to avoid the impact of operating errors on the experimental results. 4. After the experiment, data processing and analysis are required, and the experimental data is stored in accordance with relevant regulations.
