Important safety warning — please read
Never use a detector of this kind as your only proof that a circuit is dead. These miss live conductors behind shielding, in metal conduit or in screened cable, they fail silently with a weak battery, and they alarm falsely from induced voltage on nearby wiring.
Always prove dead with a two-pole voltage tester, and prove the tester on a known live source before and after. A pen is an indication, never a confirmation.
Test it on a known live circuit before every use.
Do not use the screwdriver end on live work. The tips are not insulated for live working, whatever the handle is made of. Isolate the supply and lock it off first.
It detects AC only. Mains electrical work is regulated in many countries — if you are not qualified, use an electrician.
