this very sorry la, me not pro about this, just can help you to get some very little information. maybe you can try in small piece of metal like key or screw. according the guide if too much voltage will make the color become black.

but i think that guy also bring it to the shop and ask them to help. because invest the equitments i don't think so, cause you won't need all the time,. btw if you want i can help you to search company that have provide this service.
