Require users to use their abilities when testing authentication and troubleshooting. The main function test is to determine whether the wiring of the link is standardized through various tests. If not, there is something wrong with the wiring link. The diagnostic function of troubleshooting and testing equipment is the ability to find and analyze its failed decisions. These test functions allow users to correct the wiring errors that can be eliminated in the shortest time. After solving the wiring fault, the best way is to connect the certification test again to ensure that the line meets the specified standards.
It can't be used in laboratory testing equipment, and the accuracy of laboratory level can only be close to that of field tester, so the accuracy and precision of traceability tester are very important. TSB-67 standard clearly stipulates the grade of this precision field tester. Whether it is testing basic links or channels, such as integrated wiring certification test equipment, two precisions must be met. The manufacturer claims that the accuracy index is recognized by an independent certification body, and the user cannot thoroughly understand the technical problems of the instrument, so it is the most convincing way to produce the quality assurance index of testing equipment by a third-party independent certification body such as UL. When selecting test instruments, users can ask questions from independent certified manufacturers.
Also note that the test equipment can track the accuracy of the problem. As a high-precision testing instrument, certification is measured according to the requirements of standards, and the precision testing equipment must be traceable. The so-called traceability is a set of processes and methods, and the accuracy of instruments can be traced back to national (international) standards. Precision testing equipment, testing equipment is to determine the basic authorization and accuracy is time-limited, in general, the accuracy of the detector can only be saved for 6 months to one year. Therefore, when you choose five types of precision test equipment, such as network cable, the supplier hopes to obtain traceability evidence, and requires the process, method and calibration of the instrument to be traced back to international standards, so as to ensure the fairness and authority of your test equipment procurement.
Test instruments in the field of fault diagnosis should provide a series of fault location and wiring systems to find a single cable or error. Distance and test equipment for diagnostic or troubleshooting tests.
The next test method of Tiandi line combines digital pulse and digital signal processing technology. Crosstalk can be displayed completely graphically. The test case is link. Analog frequency scanning technology measures the value of the entire next page link, so the test can only report the "qualified" or "unqualified" results of the link to the user. Using TDX technology, a very important advantage of test equipment is that it can indicate that signal crosstalk occurs at a higher link position.
Technical support and services
Inspection and test equipment manufacturers can provide comprehensive, professional and fast technical support and services, and can also choose an important aspect of testers. It also includes whether these localized support and services, maintenance and upgrades can be truly localized. Does the calibration tester return to the original factory? For these problems, the manufacturers of active test equipment give users few explanations, but users must be clear about the problems.
Other testers are used for field testing, and their design should be based on the construction site environment, so it is best to have a field tester with good resistance to harsh environment. Attention should also be paid to the power management ability. After the tester is suddenly powered off for a few hours, the user does not want it, and all the test results are stored and disappeared.
Ideal tester
From a technical point of view, an ideal cable tester should first meet the performance requirements of secondary accuracy of channels and basic links; From a more practical point of view, it is also a faster test speed. In addition, testers help users find that wiring fault diagnosis is very important. Because the purpose of testing is to get a good link, not to distinguish between good and bad. Test equipment must be able to quickly inform users of the location of link failures, which is a very valuable function. The test results of other factors that need to be considered can be dumped and printed, which is simple to use and supports other types of cable tests.
