Hi all,
I don't know anything about electronics but im after a device which I don't know the name of...
It looks like a pen and it detects power/current and lights up. Its good for checking power cables for blown fuses etc. There are no electrodes...you just place it near the cable and it lights up if it detects power.
I just need to know what they call these things so I can find one online and buy it.
Many thanks Chris
