What is the accuracy of the spring tester?

Spring testing machine is a kind of mechanical equipment used to test the physical properties of springs such as tensile, pressure and displacement. Its accuracy is usually described by the error range, not by specific numbers. Generally speaking, the accuracy of the spring testing machine depends on the conditions of its design, manufacture and use. For example, the mechanical accuracy of the machine, the accuracy of the sensor, the measured ambient temperature, humidity and other factors will affect the accuracy of the test results.Under normal conditions of use, the accuracy of the spring tester is usually between ±0.5% and ±1%. However, the specific accuracy range also needs to be determined according to the specifications of the machine and the needs of users. Therefore, if you need more accurate information, it is recommended to refer to the manual of the machine or consult the manufacturer.
