1、The socket tester is used to quickly detect the correct elecical connection of the socket. 2、With LCD display, quickly test frequency, phase voltage L_N, leakage voltage N_E, and accurate measurement. 3、Multifunctional elecician detector, can test the protection system to ensure household elecical safety. 4、Can save a lot of time to test socket problems, small and por, sui for elecicians. 5、Widely used for elecical maintenance testing in schools, laboratories and factories, office socket testing, switchboard testing and wall socket testing.Item Type: Socket TesterMaterial: ABSMain Functions: 3-pin socket line sequence detection, phase voltage L_N detection, leakage voltage N_E detection, leakage switch RCD detectionWorking Voltage: 90-250V 45-65HZPhase Voltage Measurement Range: 90-250V, 45-65Hz, Accuracy: ± 2.0%+2Leakage Voltage Measurement Range: 0-99V/45-65Hz, Accuracy: ± 2.0%+2Working Temperature: 0℃-40℃Working Humidity: 20%-75%RHStorage Temperature: -10℃-50℃Storage Humidity: 20%-80%RHAltitude: ≤2000 MetersRCD Current: >30mARCD Working Voltage: 220V±20VGFCI Test: >5mAGFCI Working Voltage: 110V±20V ground fault current leakage protector; it is a special protection device for the North American marketHow to Use:Plug the tester into a standard 3-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 to determine what kind of socket wiring is wrong, and then unplug the tester. When the wrong wiring is detected, please find a professional elecician to repair the wiring. width=582 height=160 height=20 et2 height=20 width=266 / et2 width=105 Red/ et2 width=113 Red/ et2 width=98 Red/height=20 et2 height=20 width=266 Correct/ et2 width=105 ●/ et2 width=113 ●/ et2 width=98 ○/height=20 et2 height=20 width=266 Missing Ground/ et2 width=105 ●/ et2 width=113 ○/ et2 width=98 ○/height=20 et2 height=20 width=266 Missing NeualLine/ et2 width=105 ○/ et2 width=113 ●/ et2 width=98 ○/height=20 et2 height=20 width=266 Missing Live Wire/ et2 width=105 ○/ et2 width=113 ○/ et2 width=98 ○/height=20 et2 height=20 width=266 Live and Ground Reverse Connection/ et2 width=105 ○/ et2 width=113 ●/ et2 width=98 ●/height=20 et2 height=20 width=266 Live and Neual Line Reverse Connection/ et2 width=105 ●/ et2 width=113 ○/ et2 width=98 ●/height=20 et2 height=20 width=266 Live and Ground Wire Are Reversely Connected, Lack of Ground/ et2 width=105 ●/ et2 width=113 ●/ et2 width=98 ●//Note: Phase and ground are wrong and lack of ground: the live wire and the ground wire are reversely connected, and the ground wire is not connected.
