im relatively new to vaping, i have a uwell dual .5 coil. My ohms read .23 on my 150. Again, im new and im sure this sounds like a stupid question to some of you, but isnt it suppose to be at .5 ohms by default? I dont know how to caibrate resistance or if i can. But just curious why my coils say .5 but my box is giving me .23. Once more i am fairly new so go easy on the question but i thought the ohms calibrates to the coil.
