I'm not sure if it's malfunctioning or if I did something wrong. Here's some background of the problems that I'm having. I built a dual coil nickel ni200 build on it, it came out at .17 ohms. It wouldn't fire. Even though it says it will fire down to .15. Then it said atomizer short. So I rebuilt two more times and the same things happened, even though I rebuilt using a bigger diameter and more wraps it said the same exact ohms as before. So I took it apart again, rebuilt two more coils and now it is saying .07 ohms. Which is too low. So I figured, I've never built dual nickel coils so maybe this is the problem and then removed the one coil. But then it said 0.12 then 0.14 then 0.17 then I fired it. It was firing but making little to no vapor. So I checked that both leads to the coil, both were good, making sure not to touch anything. And then I fired it. And the cotton, that had juice on it, lots. Caught on fire. It immediately went out. But it was a decent size... I was scared and startled... to the point to make me put down the mod and Rda and remove the batteries for the night. And now I'm here. Please help!
