EU Plug Digital Socket Tester with Backlit Screen for Voltage Leakage Protection Detection - SOCKET WIRING SEQUENCE TEST: Insert the tester

the orange backlight will illuminate to indicate a wiring error. Refer to the display to identify the specific type of wiring error., SOCKET WIRING SEQUENCE TEST: Insert the tester into a standard three-pin power socket. If a wiring sequence error is detected DATA RETENTION: After inserting into the socket, the data automatically locks after three seconds. Once locked, press the unlock button to release the data. LEAKAGE SWITCH DETECTION: Insert the tester into a three-pin socket, ensuring that the display indicates correct wiring. Press and hold the RCD button for more than 2 seconds. In this case, a functioning residual current device (RCD) should trip, displaying the tripping time. The button indicator will flash, indicating the completion of the tripping process. If it does not trip, it suggests a malfunction in the residual current device. AUTOMATIC SHUTDOWN: If there is no operation within 5 minutes of powering on, the instrument will automatically shut down.
