The moisture meter can quickly measure the moisture content of the grain. 1. Advanced socket tester to quickly detect the correct electrical outlet connection, can test the protection system to make sure the electrical safety of your home . 2. With its LCD display, it can quickly and accurately measure phase voltage (L_N) and leakage voltage (N_E). 3. 7 LED light modes, there are 7 kinds of easy to read indicators indicating the status of the socket, easy to evaluate. 4. Widely used in electrical maintenance testing in schools, laboratories, factories and other social areas, office socket testing, power strip testing and wall socket testing. Testing socket problems can save a lot of time. 5. Portable design, small size, light weight and easy to use. . NETWORK SOCKET TESTER DETECTOR FUNCTION RCD Specification: Condition: brand new Item Type: Socket Tester Material: ABS Color : as shown in the picture Main functions: Three-pin socket cable sequence detection, phase voltage detection (L_N), leakage voltage detection (N_E), differential circuit breaker detection (RCD). Operating voltage: 90-250V Phase voltage measurement range: 90250V Accuracy: (2.0 percent 2) Leakage voltage measurement range: 099V Accuracy: (2.0 percent 2) Operating temperature: 0C 40C Operating Humidity: 20 percent 75 percent Relative Humidity Storage temperature: -10C 50C Storage Humidity: 20 percent 80 percent Relative Humidity Height: 2000m RCD Current: andamp gt 30mA RCD operating voltage: 220V 20V Connect the tester to a standard electrical outlet with three holes. If an error is detected in the order of wiring of the socket, the red backlight will light up, indicating an error in wiring. Then observe the indicator and the function comparison table to determine what type of socket wiring is incorrect, and then disconnect the tester . If incorrect wiring is detected, a professional electrician should be found to repair the wiring. Red Correct connection Earth wire not connected Neutral wire not connected Phase wire not connected Phase wire and ground wire reversed Phase wire and neutral wire reversed Phase wire and ground wire reversed, ground wire not connected List of packages: 1 x Socket Tester 1 x User Manual . NETWORK SOCKET TESTER DETECTOR FUNCTION RCD Note: This tester cannot distinguish neutral wire from ground wire. Please note that the new type and old type of this product will be shipped randomly and make sure you don't mind before placing your order. When there is no ground wire, the screen backlight is displayed in orange and green when there is a ground wire. . NETWORK SOCKET TESTER DETECTOR FUNCTION RCD
