Will the tensile force return to zero after the tensile tester is broken?

Tensile tester is a device used to test the tensile properties of materials. In the tensile test, the sample is stretched until it is broken, and the reading of the tensile tester usually returns to zero. This is because the tensile tester usually uses an elastic measurement system to measure the tensile properties of the material. When the sample is broken, the force measurement system of the tensile tester is usually subjected to a sudden impact force, resulting in a zero reading. However, the specific instrument settings and operation may affect the readings of the tensile tester. For example, some advanced tensile testers may have more complex force measurement systems, which can keep the reading stable after the sample is broken.In addition, some tensile testers may also have the function of automatically recording force-displacement curves in order to analyze the tensile properties of materials more comprehensively. Therefore, although the tensile tester will reset the reading to zero after pulling in most cases, the specific instrument settings and operation may affect this result.
