Plugin Circuit Tester – Identify Electrical Issues Quickly and Safely • Instant Circuit Status Check Simply plug the tester into the socket you want to check. LED indicators will immediately show whether the circuit is functioning normally or if a fault is present. Compare the LED pattern with the reference chart to determine the exact problem. A red backlight alerts you instantly when a fault is detected. • Comprehensive Fault Detection Capable of identifying multiple common wiring problems, including Open Ground, Open Neutral, Live/Ground Reverse, Live/Neutral Reverse, Live/Ground Reverse (duplicate listing per specification), and Missing Ground. Equipped with an RCD test button, allowing you to verify that residual current devices are working properly, reducing electrical safety risks. • SafetyFocused Construction Made from fireresistant ABS housing, providing insulation to help prevent electric shock during use. The shell withstands heat generated by short circuits, reducing the risk of fire. • Wide Voltage Compatibility Suitable for voltages from 48V to 250V, 4565Hz, including areas with unstable voltage supply. In addition to fault detection, the tester displays realtime LN and NE voltage readings to assist in evaluating circuit performance. • Practical Use Scenarios 1. Homeowners troubleshooting faulty outlets before calling an electrician. 2. Maintenance staff quickly checking office or commercial building sockets for wiring issues. 3. Technicians confirming proper RCD function during electrical safety inspections. • Key Advantages Quick plugandtest operation saves time and effort Detects a full range of wiring faults with LED guidance and clear chart references Builtin RCD test function ensures breakers are working Durable, fireresistant ABS casing adds an extra layer of safety Compatible with a wide range of voltages and frequencies for versatile use This tester delivers fast, reliable diagnostics for residential, commercial, and industrial electrical systems, ensuring safety and preventing damage by identifying problems before they become hazards.
