I picked up a Therion BF (first DNA device), and it seems to read the resistance of every atomizer I throw on it between .05-0.10 higher than other mod I've got. Occasionally, I'll get a 'short' or 'check atomizer' warnings as well. I've tried cleaning the 510 connection with isopropyl and that didn't seem to help. I popped the 510 connection off to get a look at the soldering and nothing seemed to be wrong. When I screwed it back down, the mod was reading my atomizer correctly, but it's since been creeping back up (began as a 0.53 and now reads as a 0.61 - simple kanthal coil). It's working for now, but I'm afraid of getting the short/check atomizer errors again. What all can I do to try and figure out what's wrong with it? EDIT: Ground wire was bad. Soldered in a new one. All fixed. Yay.
