Feature:1. - Compact \u0026 Portable: Advanced socket tester for rapidly detecting whether the wire connection of a socket is correct or not. Compact size \u0026 light weight, convenient to use.2. - VA Color Display Screen: The high-definition display can see the screen value clearly in the dark environment.3. - 8 Display Patterns: With 8 easy-to-read indicators to indicate the state of the socket, easy to judge: Wiring correct, missing neutral wire, missing earth wire, earth wire is missing, reversed order, reversed order, lack live wire, live symbol.4. - RCD Test Button: When the button is pressed and there is no trip and power failure, there is no leakage conservation. One Click to know the working state of the leakage protector, protecting your security against the risk of electric shock.5. - Wide Application: Widely used for electric maintenance testing, office sockets testing, power strips testing and wall sockets testing in schools, laboratories, factories and other social fields.Specification:This AC11 smart socket tester is mainly used to detect polarity of power socker and safety of leakage switch. It can quickly and accurately detect ground wire neutral wire live wire, leakage, trip, socket voltage and the wiring of the socket and then simultaneously display the results on the LCD LED screen.Features:- Compact & Portable: Advanced socket tester for rapidly detecting whether the wire connection of a socket is correct or not. Compact size & light weight, convenient to use. - VA Color Display Screen: The high-definition display can see the screen value clearly in the dark environment.- 8 Display Patterns: With 8 easy-to-read indicators to indicate the state of the socket, easy to judge: Wiring correct, missing neutral wire, missing earth wire, earth wire is missing, reversed order, reversed order, lack live wire, live symbol.- Non-contact Induction: When a nearby AC voltage is detected, the lightening symbol/index grid flashes and an alarm beep sounds.- RCD Test Button: When the button is pressed and there is no trip and power failure, there is no leakage conservation.
