Ok , so I don't know if I'm having a problem with my tank or what but... A few weeks ago I threw in a new t8 coil in my baby beast ( .15 ) and it read .26... I kept trying and trying removed it from my alien, clicked the fire button so it displayed no coil, then would try again, read .246, then .28..
Today I just threw in a brand new x4 coil ( .15 ) and it's doing the same thing. It's reading .228, removed it from the mod after a few puffs, and it reads .246.... I don't remember either the q2 or t8 being much more than .01 off.. ex , the q2 ( .4 ) would read like .405, or .411..
