【Easy installation】Grounding fitted is very easy to use. When any of your skin is in, you will then be directly connected to the earth, providing grounding benefits. 【Installation and Testing】You need to use a test pen to test whether the bedsheet is conductive, then use a yellow grounding switch to test whether the socket can be grounded properly (it is very important to ensure that the socket is grounded properly), and then use a grounding wire to connect the bedsheet to the socket grounding hole.
