I received my first DNA 133/200 yesterday, a Starrss Player with a 1100mah lipo. Iâve had many DNA 40s but this is my first go with escribe. I'm having an issue trying to do a resistance calibration using the brass adapter from Smoke Free Mods. The resistance came preset at .006, I reset to 0 then loaded the new settings and opened the calibration screen. It doesnât seem to detect the brass adapter, the question mark stays on the screen no matter how I try to screw it on. Iâve cleaned the connector, loosened it, tightened it, wiggled my nose and nothing except once it read but as soon as I removed my fingers went back to the question mark again. For kicks I tried 4 different atomizers with SS coils and it read them all but doesnât want to read the brass adapter, any suggestions? I set the resistance back to the factory preset of .006 for the time being and it seems to be ok so I'm not sure if it really needs it but I'd like to at least compare and figure out why I'm not able to get a reading with the sfm adapter.
