Precautions for multimeter to check leakage
1. When using the 200M block of the ohm block of the multimeter, be careful not to touch the metal part of the test pen with your hands during measurement, otherwise the reading will be inaccurate.
2. When measuring each electrical equipment, pay attention to discharge first to prevent the capacitive current in the electrical equipment from hurting people.
This method is a relatively safe method to find the fault point in the state of no power. This method is also suitable for power users and power plant leakage searches. However, when searching, not only should the incoming power line be disconnected, but also the neutral line should be disconnected to avoid electric shock accidents.
