Ensure electrical safety and accurate socket wiring diagnostics with this advanced Socket Tester, designed for quick and easy testing of three-pin power sockets. Featuring a high-definition backlit LCD screen, this tester provides clear and precise readings of socket wiring conditions and AC voltage, making it an essential tool for electricians, technicians, and DIY enthusiasts. Key Features: · Simple Operation: Easily insert the tester into a powered three-pin socket to instantly determine wiring conditions and AC voltage from the clear instrument display. · Socket Wiring Sequence Test: Detect wiring sequence errors with an orange backlight alert. The display specifies the exact type of wiring fault, including open ground, open neutral, open live, reversed live and ground, reversed live and neutral, and missing ground wire scenarios. · Data Retention Function: Automatically locks measurement data after three seconds for convenient reading. Press the unlock button to release the data for retesting or clearing. · Leakage Switch (RCD) Detection: Test the functionality of residual current devices by holding the RCD button for over two seconds. A proper trip is indicated by a flashing button and display of the tripping time. Failure to trip signals a potential RCD malfunction. · Automatic Shutdown: Conserves battery life by powering off automatically after 5 minutes of inactivity. · High-Definition Backlit Large Screen: Provides excellent visibility in dim environments, ensuring clear and easy-to-understand test results at a glance. · Product Safety and Reliability: Rated CAT II 300V for safe use in household and commercial environments, compliant with EN61010-1, EN61010-2-030, and EN61326-1 standards. · Wide Application: Ideal for testing socket wiring safety in homes, offices, shopping malls, and other indoor locations.
