DEWENWILS Socket tester with RCD test and LCD voltage display, indicator light display, FI test, 48-250V/45-65Hz, CAT ll 300V-Quality Guarantee

Description

Multi test functions: the socket tester is used for checking the displacement condition and RCD testing, fast and accurate; LCD display shows the voltage clearly

Diagnosis status: 3 indicator lights and the German error chart shows 7 common suspicion errors (earth not connected, zero not connected, phase not connected, phase/earth reversed, phase/zero reversed, phase/earth reversed, phase / earth reversed, earth not connected)

RCD test: the socket tester tests FI circuit breaker by simulating ground fault states to confirm operation; it checks standard sockets wired parallel to FI circuit breaker sockets; please use this function carefully with normal sockets to avoid triggering the house wiring
