New to me, probably old hat to most of you.
Strange little problem with the VT133 jumping out of TC while using the Crius Plus (V-Deck) and a dual 24g SS316L build at 0.20Ω. The VT133 read it as 0.21Ω and all seemed fine until you fired the build. The temperature reading would jump to 5 digits 413?? and then switch to OFF. I removed the RTA, reset the resistance and put the RTA back on, same problem. Pulled the deck checked the coils for cut leads and made sure the grub screws were tight, all good.
Put it back on the VT133 and same problem. The Crius vaped fine at 65W in power mode so I know it couldn't be the build. I tried it on the VT75 and found the same problem...
Bingo
The base of the Crius Plus has interchangeable decks. Conductivity is made with a moveable brass pin through a rubber grommet on the 510 connector, this butts up against the decks main post. I had cleaned both of those with a piece of paper towel when I put the build in and they were not dirty. So I took the deck out again and applied a little 600 grit wet/dry paper to both the ends of 510 pins and deck post.
Put it all back together, the VT133 read it as 0.20Ω , hit the fire button and it's all working perfectly now. The pins didn't look corroded at all, but there must have been just enough to cause a big jump in resistance and the VT133 to kick out of TC.
This is the first time I have experienced the DNA jumping out of TC and I'll have to watch the Crius to see if it does it again.
