The reason for the failure of the cable fault tester The cable fault tester manufacturer, the cable identification instrument manufacturer The cable fault tester is an important tool for maintaining various cables, but some problems will inevitably occur during use. The reason for the failure of the cable fault tester The cable fault tester manufacturer, the cable identification instrument manufacturer The cable fault tester is an important tool for maintaining various cables, but some problems will inevitably occur during use. The fault analysis of the cable fault tester is carried out during the testing process. In the actual application process, some fault phenomena will also occur in the cable fault tester, which seriously affects the performance of the cable fault tester. Now, a breakdown of some of the simple fault types in the cable fault tester allows users to repair the equipment themselves without the hassle of returning to the factory.
1. After the cable fault tester is turned on, the power indicator turns off. If the screen does not light up, the battery may be dead and the cable fault tester needs to be charged.
