I'm very very new to building my own coils on my new rda. Right now I'm using the built in ohm reader on my iStick 50 (tuning it on and attaching the RDA with the coil and seeing what it reads before firing) and, so far, I've yet to blow anything up and have even managed to make a couple of vapable coils 
My question is it safe checking the resistance this way or do I really need a dedicated meter?
