The multitester is more than just a conventional voltage tester. The built in battery powered sensor allows the multitester to perform a number of different function without the need to dismantle a suspected faulty item or have any contact with live parts.
The multitester 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 instruction supplied with the multitester. Never use a multitester 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.
