First time posting... with that said, i picked up a Sig 213 yesterday. After about 5 minutes into using it on wattage/power mode, i noticed that the ohm/coil resistance was jumping from .25 to .33/.34 after every hit. If i wait a few seconds and tap the fire button, it starts going back down eventually back to .25. I'm using a crown with .25 coil. Thought maybe it was the crown so i tried my kanger with .5 coil and same thing happened. Never experienced this issue before with my kbox 120 or kbox mini. I've seen the resistance for .25 coil that read .26 or .27 but it was steady at that and never fluctuated. Seeing how new this is, I haven't been able to find any threads on this yet. I have however found information on previous Sigelei models that did this and that it was in fact an "issue". Anyone else experiencing jumping resistance with their 213 in power/wattage mode or is mine jacked up?
