I actually have had the opposite issue. I can't get it to recognize a new device and give me the left/right message a lot of the time when changing tops. Even when changing wire types it will often not ask if it is a new atomizer. When it doesn't ask it doesn't seem to read it correctly like it will read at .14 on a .08 build. I have to take it off and put it on a few times to get the message and then it will read the ohms correctly.
