My V3 keeps giving me incorrect error messages. First it tells me check atomizer. Everything was fine on it. .4ohms, no shorts. It was fine on my clone and ohm meter. I rebuilt it at .6 and it was fine. I tried it at different wattages and it didn't change anything. Then it told me it shorted which it definitely did not. Again it looks fine and worked fine on everything else. After that I briefly got a message saying weak battery on a mostly charged, brand new vct4. I don't think it's a problem with that atomizer. I'm using a Zenith V2 clone.
