ITEM NAME:EU Automatic Electric Circuit Polarity Voltage Detector LCD Socket Outlet Tester Product Description Description: ET89UK Intelligent Socket Outlet Tester with LCD Screen Display Voltage Frequency Detector for Home Appliance Testing Description: The intelligent socket tester is mainly used for the polarity detection of power socket connection and the safety detection of leakage switch, which can quickly and accurately detect the connection of the socket. The intelligent digital display tester can simultaneously detect the voltage, frequency and wiring correctness of the socket. Feature: 1. Intelligent detection to ensure the safety of household electricity. 2. RCD test, one key detection of leakage protector status. 3. A general measuring tool, widely used in schools, laboratories, factories and other fields. 4. Light and convenient, easy to carry and store. 5. With three indicators and LCD screen, the tester is easy to use for beginners. 6. There are six states in the program, but only one state can be displayed at a time: correct, lack of grounding electrode, lack of neutral conductor, reversal of charged neutral line, reverse of charged grounding electrode, and leakage. 7. The voltage and frequency are displayed in the lower part of the LCD screen. Specification: Plug: UK Working voltage / measuring voltage range: 220-250V Working current of the whole machine:
