Whether the wire testing machine needs to be calibrated

　　To ensure the accuracy and speed of the certification test and the authority of the test results, it is necessary to carefully choose a tester that suits the needs of users. Of course, the user requires that the tester used has the ability to authenticate and troubleshoot at the same time. The most important function test is to test whether the various properties of the wire can pass the various tests of the customer's standard. If it cannot, it means that the wire is unqualified.

　　The wire comprehensive tester generally has the functions of testing the unilateral, insulation and high voltage of the wire, and some can test the wire with electronic components, and can accurately measure the specific parameters of the components (four-wire tester). This kind of wire comprehensive tester is used by wire manufacturers such as earphone cable function, USB cable, medical cable, car cable, non-standard cable, etc. The test speed is faster than the ordinary high-voltage wire tester on the market, and the AB end judgment is more accurate. .
