The Megger MST210 Socket Tester is designed to provide a quick and easy
indication of wiring errors that may be present at a socket outlet. Using
simple green and red LEDs, correct wiring can be verified with no need to
isolate the supply or disassemble the socket.
Simply plug the tester into the socket. If the wiring is correct, two green
LEDs will illuminate. If either the green LED does not light or the red LED
comes on, there is a wiring fault. By referring to the table below, the
combination of LEDs shown will indicate the wiring fault present. Technical
advice may be obtained from Megger Product Support at +44 (0) 1304 502102.
