MAKINGTEC Socket Tester, Circuit Testers, Rcd Plug Tester, Mains Outlet Tester with LCD Display, Display Digital Electrical Voltage Tester for Socket Test Safety Inspections, 90-250v, HT107E

🔌【Multiple Voltage Measurements】The power outlet tester is used to measure voltage. Including 220V±20V RCD working voltage, 110V±20V GFCI working voltage, 90-250V voltage measurement range, 0-99V leakage voltage range. Allows you to easily detect voltage data about what you want to know.
🔌【Check the Wiring Condition】The socket tester is also used for polarity detection of power socket wiring. Including correct, lack of ground/neutral/live, reverse live, reverse live neutral, reverse neutral, and lack ground, seven wiring methods. Help you quickly detect whether the wiring is connected correctly, and troubleshoot common hidden dangers of the line.
🔌【Safe Insulation Design】This RCD tester with LCD display adopts insulation design, because there is no risk of electric shock when using it. Guaranteed your life safety.
🔌【Check Whether the Leakage Protector is Good or Bad】Insert the tester into the three-hole power socket with correct wiring, press the RCD button (less than 3 seconds), then the normal leakage switch will trip. If it does not trip, it means that the leakage switch has invalid. Help you troubleshoot potential leakage.
🔌【Practical Circuit Safety Testing Tools】The socket tester can be used to test the daily circuit safety inspection of the family, the circuit inspection of the office and shopping malls, the inspection of the factory equipment, and the acceptance of the circuit of the new house. Meet your needs for circuit and voltage detection in different occasions.
