Yup, both are identical VT 510s. I opened the mod up and played around with the wiring while firing it, which didn't result in any change in variance. I ordered some additional 510s from Varitube today and will swap it out when they come in. It very well could be that the mod is reading the spring...I had to drill out the 510 for the 14ga. wire, so maybe I messed something up in the process. Oh well...two big issues in one day...a dead board and wonky 510. At least I have one good DNA200 running at the moment (my C-Frame).
The board that reads 0.48ohms, does it always read the same resistance? Have you tried a higher ohm kanthal build to test? Say 1.0ohm or something like that? Something higher than 0.48
And is the variance between the 2 always the same value? (ie: +0.32 ohms or whatever)
That sucks cotay, sorry to hear about the problems. My screen on my dna200 just died on me last night, the one in the BRD1300 box. I'm trying to get Evolv to warranty it, the screen just gradually died over the course of a couple week's with no physical signs of damage or creases in the ribbon cable... I've replaced it with one from a DNA40 large screen temporarily... well in truth, when the replacement screen comes in I'll put IT with the dna40 and leave the dna200 brd1300 box alone. I'm sure continuously removing and replacing those screws can't be good for the plastic posts.
Keep us all posted, I'm curious to know what the eventual solution will be.
(oh last thing, it was mentioned earlier that escribe has a ohm adjustment setting, so you can program your board to read and treat the atty at a given resistance, as I understand it you use this to off set any variance in ohm reading, assuming the increased value is constant across all your builds)
