Load sensors are used for load measurement. The measurement area of the experiment is usually within the range of 20% to 20% of the rated load. When the test is below 20%, the measurement accuracy can be improved by switching the range or adding. Imada tensile and compression testing machines are all manufactured with the load accuracy of JIS level 1 testing machines. The longitudinal elastic modulus (Young's modulus) and spring characteristics of displacement measurement materials are necessary for load displacement relationships. Displacement is expressed by measuring the movement of the testing machine, but there may be slight differences between the movement of the testing machine and the movement of the fixture installed at the front end of the force sensor, depending on the deflection of the force sensor and the rigidity of the testing machine. Correct the difference by adjusting it proportionally to the load. The SV-55CB model is only for loading purposes. In load testing, the speed at which force is applied may have a significant impact on the measurement results. In JIS and other prescribed test methods, the test speed is generally recorded as a test condition. By inputting the numerical value of the speed, simple operations can be performed. The SV-55CB model is a variable volume type. The loop action function can be tested repeatedly for a set number of times. The upper and lower limits can be set as load and displacement. There is also a function to stop it by setting different time values. The reciprocating repetitive action function of a general tensile compression testing machine is more practical for use in relatively few repeated tests with hundreds of times. For a test with tens of thousands of repetitions, please consider using a dedicated durability testing machine. Example: There are switch durability evaluation testing machines, etc. The SV-55CB model does not have any functions. When the fracture detection function breaks, it can automatically stop and reset the origin of the tensile compression testing machine. When broken
