Yes, I ran the analyzer. This is happening with two separate tanks/coils. Both tanks/coils work fine on my old Kanger MOD (although that MOD doesn't have the temp protection). I'm using the SS316 temperature profile. I wish I could try this. The VT75 Nano doesn't have a cathode screw in the same place. I don't see one someplace else on the MOD either. A quick search doesn't come up with anything for a cathode screw on the Nano.
