[0003] According to the relevant standards, there are many test items for bus cables, involving a wide variety of test instruments. If manual testing is used, it will not only be labor-intensive, tedious, and have low operability, but it will also be impossible to guarantee the consistency of the tests and the unified management and scientific analysis of the test data, so as to meet the diversified needs of modern automated production, testing and maintenance of bus cables.
[0004] Therefore, cable testing devices often struggle to be compatible with uncommon connectors. Increasing the variety and number of connectors also makes the testing device bulky and heavy, hindering its portability and operation.
