So when I put my Nixon rda with a dual coil .32 build on it, it says check atomizer and will not fire. Now I have a co worker who has the same rda but single coil with a .7 build, put it on my m50 and it's reading .4 ohms. Has anyone had this same issue with it not reading correct and know any way to fix it? Or is it just a defect? Oh and I also have a melo sub-ohm tank that has a .5 coil and it reads just fine when I screw it on.
