GRUENERDE Grounding Pillowcase King with 15ft Grounding Cord Conductive Grounding Products for Better Sleep Health(20x36 Inch)

We have found that some customers say that there is something wrong with the cord. In fact each grounding pillowcase or sheet is tested for quality and we want to emphasize that not the grounding wire is damaged, but your test method is not right. Our grounding wire has a built-in 100kohm resistance, so the buzzer file test cannot be used, and the resistance value needs to be tested. If you need the grounding wire to be a pure conductor, we are sorry, please do not buy this product. All grounding wires of this product are equipped with 100k ohm safety resistance. We believe that safety resistors are necessary for safety. How to test the Conductivity of the cord? Step1 Prepare grounding sheet, grounding cord, and multimeter (it is not included in this grounding sheet set). Step2 Adjust the multimeter range to the ohm range, range is greater than 200 kiloohms (this step is very important, if the range selection is wrong, the multimeter reading will be 0). Step3 Measure both ends of the grounding cord with a multimeter. If the resistance is 100 kiloohms, it means that the conductivity is normal. Step4 Connect the grounding cord to the bed sheet, connect one end of the multimeter to the grounding cord plug, and the other end to any dark silver fiber of the grounding sheet. If the multimeter shows a valid reading, it indicates that the conductivity of the entire sheet is normal.
