hello everyone, i have odin 75c, but it reads a different resistance value than when i use centaurus 250c. I use the same atomizer (artemis rta) when installed in odin, cold ohm read 0.886ohm and when it puff live ohm read 0.874ohm (sometime cold ohm jump to 0.9ohm) but when installed in centaurus, cold ohm read 0.827ohm. then live ohm read 0.820ohm (cold ohm is steady) I think the 0.05ohm difference is not very significant, but the feel when it puff it's very lots of different (the feel, flavour, vapour), better with centaurus. Is this due to a different firmware? or due to hardware differences? thx
