MST210 Socket Tester

Convenient, compact plug-in style tester designed to identify wiring faults at UK 13A 3-pin power sockets.

Over 17 combinations of wiring fault can be identified including missing wires and incorrect or reversed connections.

Faults are signalled by 3 bright LED's on the front of the unit, with a simple diagnosis chart for typical errors included on the label next to the LED's. 2 green LED's signal a correctly wired socket, and a third red LED identifies a fault.

If either green LED fails to light, or the red LED comes on, a fault is present and will require further investigation.
