1. The electric pen shows that 12v is not leakage.
2. It means that the voltage value of a certain area of the product under test is 12v, but try not to use this number to display the test pen, because the number displayed by it is very easy to mislead the user.
3. In addition, pay attention when using it, be sure to touch the metal part of the end of the test pen with your hands, otherwise the test data will be inaccurate.
