HT107D LCD Digital Display Socket Outlet Tester Mains Fault Check Tool Detector Electroscope EU Plug Feature: 1. Advanced socket tester for quick detection of the correct electrical connection of the socket, it can test the protection system to make sure electrical safety at home. 2. With LCD display, it can measure frequency, phase voltage (L_N) and leakage voltage (N_E) quickly and accurately. 3. 7 LED light modes, there are 7 kinds of easytoread indicators to indicate the status of the socket, easy to judge. 4. Widely used in electrical maintenance testing in schools, laboratories, factories and other social areas, office outlet testing, power strip testing and wall socket testing. It can save a lot of time to test socket problems. 5. Portable design, small size, light weight and easy to use. Specification: Condition: Brand New Item Type: Socket Tester Material: ABS Color: As shown in the picture Main Functions: Three-pin socket wire sequence detection, phase voltage (L_N) detection, leakage voltage (N_E) detection, leakage switch (RCD) detection. Operating Voltage: 90-250V Phase Voltage Measurement Range: 90~250V Accuracy: (2.0%+2) Leakage Voltage Measurement Range: 0~99V Accuracy: (2.0%+2) Operating Temperature: 0C~40C Working Humidity: 20%~75%RH Storage Temperature: -10C~50C Storage Humidity: 20%~80%RH Altitude: 2000 m RCD Current: >30mA RCD Operating Voltage: 220V20V Plug the tester into a standard three-hole power socket. When an error in the socket wiring sequence is detected, the red backlight will light up to indicate a wiring error. Then observe the indicator and the function comparison table to determine what kind of socket wiring is wrong, and then unplug the tester. When the wrong wiring is detected, please find a profeional electrician to repair the wiring.
