Resistance changing based on how tight RSST is screwed on my Vamo?

It was weird...

I was on my first build still, I had watched so many vids, read all the materials, and it paid off! I built an excellent 2.2Ω coil, it looked great, it was vaping decent, then all of a sudden I was getting "LoΩ" warnings. Vamo read at .1Ω. I meticulously inspected the coil, it was flawless, but same deal, so I pulled the wire (which was unbroken) and rebuilt another decent looking 2.2 coil. Then later it happened again. Hmm, unscrewed the RSST atty a little and res shot up to 3.5Ω! Screwed tighter and back to .1Ω. So I unscrewed a tad and now it's back to 2.2.

It's not bad, I think it will stay, it's just kinda weird...

The center post on the RSST moves around a touch, same thing with an AGA-T if you ever get one. Cranking it down/loosening it might be making your positive wire on the coil wiggle a bit, exposing flaws in the setup if it shorts out.

I was thinking about adjusting that, not sure where it should be though as you can tightenen it way down so it protrudes way out beyond the threads. I tried to follow Pbusardo's vid and have it just barely protruding from the threads.

With the RSST, because of the fact that the center post can be adjusted from the top, I snug the post after screwing the RSST onto the device. This way, I know the positive posts are making contact.

Nice tip! (Get it?)

The positive center pin on vamo sags easily, 1 of mine (the V2 SS) would short when it sinks to a point – after using RBAs with rather protruding positive post.
Every so often, I have to prop the pin back up using a flat micro screwdriver or paper clip…

I cannot figure out how to do this, as my center "pin" is flush with the rubber insulator and I can't get anything in there to pull it up. Is this because it was pushed down by the protruding pos. post? Any way to fix it? Now it's reading .1ohm without anything screwed on, and now I'm just screwed. I just emailed smoktek....

By the way, the problem persisted and I had to return my vamo (nooooooo!) so I'm awaiting the new one now.....

As you are threading whatever devise on, as soon as it starts to feel snug stop threading it on. So many over tighten and push the center pin down so far that it shorts out with sides or negative. Also if you get that rubber insulator with juice on it, clean it up cause the juice will eat the rubber if left there.
Good luck
