I just got a Kanger Subtank and it has the .5 ohm coil installed. Prior to filling I checked the coil and then put in on my Ohm meter. Instead of .5 it is reading 1.75. I then tried it on another device and it is also reading 1.7 ohms. OK I changed the coil and put the 1.2 ohm coil in and it is reading 1.45. What may be causing this? Granted I have not filled it with juice yet but should the coils still not be reading properly? So if I wape this and it is reading 1.7 ohms will it still vape properly? By this reading at 1.7 ohms all my devices should fire it.
