Socket Tester Electrical Outlet Sound Light Alarm Voltage Checker Detector

Socket Tester Electrical Outlet Sound Light Alarm Voltage Checker Detector Description

1??EASY TO OPERATE: Socket tester plug and measure, provide digital voltage, effectively judge the fault in the circuit, useful and practical 2??LEAKAGE SWITCH PROTECTION DETECTION: Insert the tester into the socket and ensure that RCD is pressed when the display prompt that the wiring is correct. The normal leakage switch will trip at this time. If does not trip, indicate that the leakage switch fail 3??COMPACT AND PORTABLE: Voltage socket checker adopt compact design, easy to carry, whereever to test, provide great convenience for your life and work 4??LARGE SCREEN: The socket tester has a large HD screen to easily read the voltage and clearly display the wiring conditions. The screen allow you to see readings while working in dim or poorly lit conditions, such as electrical cabinets, downstairs, behind appliances, and other enclosed spaces 5??RANGE AND ACCURACY: Voltage socket detector voltage measurement range is 90?/45~65HZ, accuracy +(2.0%+2); Leakage voltage measurement range is 0?99V/45~65HZ, accuracy +(2.0%+2)
