nickel coil

F#ck, i just realized that i get low ohms because i'm using a nickel coil and i've been using it it Wat mode and i just Read that it can be really dangerous. I'm freaking the f#ck out...someone please tell me what to do?

I've just gotten this beautiful mod yesterday in an attempt to finally try TC with nickel, after further research I've read the ohms have to be locked for an accurate temperature read, I don't know how to lock it :( Every time I vape the ohm readings go from .07 to .20 Is it supposed to change...
