Test the tensile strength, compressive strength and extension of various materials, semi -finished products and finished products, can be used for stripping, tearing, bending, folding, compression, compression For testing, it is suitable for metal, plastic, rubber, textiles, synthetic chemical products, wires and cables, leather and other industries.
When using a tensile test machine, the data is inaccurate and the deviation is too large. According to the experience, you can make the following judgments.
1. The sample is not blessed;
2. The test is not zero operation at the beginning, which is the lack of traditional test machines; there is no automatic zero function, which is like driving to forget to turn around and turn steering. Lights are the same; mainly because the test speed is not standard, too fast or too slow;
3. After the sensor is used for a certain period of time, the strain occurs elastic flexion and does not return. Re -correct the coefficient of the power sensor and correct the data; the sensor is broken.
