The multi-tester is more than just a conventional voltage tester.
The built-in battery powered sensor allows the multi-tester to perform a number of different functions without the need to dismantle a suspected faulty item or have any contact with live parts.
The multi-tester is fully insulated and is supplied complete with full operating instructions and will perform the following tests: continuity, bulbs, fuses, short circuits, cable tracking, mains sockets and microwave oven leakage.
Always read and the instructions supplied with the multi-tester.
Never use a multi-tester until you are fully conversant with its use and applications.
Never work on live equipment, and if in any doubt, always contact a qualified electrician.
