For electric power workers, the scene and frequency of the transformer tester are relatively high, so what should be paid attention to when using it?


      1. When disconnecting the cable connection, always start from the device that delivers the output power.

      2. When the device has output, never connect or disconnect the detection target. It is because the kinetic energy stored in the external detection is likely to cause severe high voltage.

      3. During testing, always keep a terminal on the high voltage side of the transformer grounded.

      4. Do not insert other objects into vents or input/output ports.

      5. Before putting the tester into operation, check whether the tester is visibly damaged. 6. Do not operate the detector in rainy or humid weather.
