Note:
1. Socket tester displaying "Correct" only means that the pole is connected correctly, but does not mean that resistance value passes designation standard.
2. Only passing "Creeping Switch Test", it can finally obtain the earth resistance value to test whether the Protection System works well or not.
3. To ensure your safety, don't make the insert out of shape to affect the test result. Forbid testing in public without permission.
4. Turn off the electrical appliances before checking the power protection systems to ensure no harms.
