电缆测试并不能提高其性能。测试只是确认所安装电缆的性能和功能能否达到所期望的目的。只有使用能满足特定要求的测试仪器并按照相应的测试方法所得到的测试结果才是有效的。 所谓认证测试,它是通过一系列的测量来检查它们是否符合某种标准。这个测试标准必须定义一组测量的参数、使用的测量方法、每个参数通过与不通过的条件以及必须使用的测试仪所需要达到的指标和精度。 Cable testing does not improve its performance. The test simply confirms that the performance and function of the installed cable have achieved the desired purpose. Only test results that meet the specific requirements of the test equipment and in accordance with the appropriate test method is valid. The so-called certification test, it is through a series of measurements to check whether they meet a certain standard. This test standard must define a set of measured parameters, the measurement method to be used, the pass and fail conditions of each parameter, and the required specifications and accuracy of the tester that must be used.
