I did read the first posts
I was just wondering how you came up with the initial values you used for testing, and how you determined that your testing methods were accurate?
Not trying to bad mouth the research, just curious about the process is all. Just seems that 10NP = .001 isn't something that is explicitly states anywhere, but a determination that you made based on testing. How did you test this?
From post 2:
Fire a coil at a given starting resistance. Monitor the screen, matching the live resistance display against the live temperature display. Find the point where these settle down, ie it's hovering around the same resistance and the same temperature. Check this on a TCR calculator, putting in the starting resistance, starting temperature, ending resistance (as shown on screen), ending temperature (as shown on screen) and the calc will tell you the coefficient used for that value.
Repeat tests at a range of NPs to be sure.
Within about 10 minutes of such tests it became apparent that the NP value was simply the coefficient - when NP was 60 the coefficient used was 0.006.
I would have declared it as that with full confidence immediately, had I not been at the time confused as to why the default was then NP70 and Titanium was better at NP42 not 35. But since it's become apparent that these are necessary adjustments counteracting the chronic low resistance reads of the chip.
Now that the new batch of SXK appears to have fixed this, we will be able to go back to using just the correct NP value.
Thanks, I just ordered this to compare with batches have coming from SXK
I gotcha, so the only test equipment you've used so far is just the infinite mod?
You had mentioned not having test equipment that could measure the temps accurately so I was a bit confused how you came up with the results.
Makes better sense now...

Sadly bloke I have VERY LIMITED experience with nickel wire and won't be buying any as u have a nickel allergy but I did try a friends Occ Ni200 in my Subtank Mini and got dry hits at NP 70 and 420 temp but also irritated my throat which was why I wanted to use someone else's first. My following your early progress and the early reviews of the SXK mods is what sold me, the "native" use of Ti and SS was what I was really after, NiChrome did the same for me as well.
Yes, that's all that's needed for NP calcs. In fact accurate temperature test equipment would cloud the issue.
All we want to know is "what TCR value is the mod using" at given NP values. That is simply a mathematical calculation the mod performs, and the result is visible on-screen by comparing the two values.
If we checked the real temperature we would be clouding its calculations with its final accuracy - plus the accuracy of the coil, and of the external temp sensing itself.
Thankfully SXK put the live resistance read on screen - without that, it really would have been guesswork.
OK thanks. Dry hits at 420 with an OCC does strongly suggest NP70 is now too low - a more normal setting for OCC coils is 500+ as their high static resistance/poor stability of resistance tends to require higher temps.
Then again, that instability also means any quick test/result cannot be conclusive, so we'll have to see.
Yeah Ti and SS is much better than Ni200 anyway. I can't really imagine I'll use Ni200 again at this point - well probably I'll test twisted Kanthal/Ni200 to compare that against bare Ti/SS and twisted Ti/SS and the other combinations. But right now I can't see why I'd use bare Ni200 again, no real point even though I don't have an allergy!
I could buy a brand new SXK VS from a buyer who didn`t like the 10 second max vaping time.
Jesus, how long do they want to vape for??
I will say 10s is a pointless limitation with TC - my Waidea limits at 24s. But probably they wanted to simplify it with a single timeout, and power mode does need a cutout.

We have confirmation that a newly received VS rDNA has the New Atomizer message and therefore surely the fixed resistances:
So yes they are rolling out to all mods.

That's good as don't expect a reply till after midnight now which is 8am China time
I didn't get a reply to my FB yet. Maybe I should have emailed or Skyped instead.
For ordering they told me to talk to 'Allen' - is that who you're dealing with, @Quantum Mech ?
PS. they're 7 hours ahead aren't they? If they're in Shenzen. They don't have daylight savings/BST, so it's 7 hours during our summer. 1am for 8am.

Oh I just googled China time, will be making Zzzz's by then so tomorrow now
Yep nice fella with good English too

Hi Bloke,
yes I just copied it this morning to my gdrive and gave it a quick look.
You did an impressive work, really!
I'm unfortunately on the move for the next few days, so I'll have to wait before being able to play with it and do some tinkering, you'll probably be on version 5 by the time I'll get back to my vaping desk
(but I'll be constantly reading this thread, so please keep me in the loop).As a not-so-side note: I received yesterday a zero clone (bought on oceanvapor) and I just played a little bit with it, but I'm quite sure it's asking "new coil up / same down" at every power-up and/or atty change, and nonetheless with the 2 attys I've tried it (K4 and squape @ about 0.16 ohms, ni200) it is _still_ reading about 0.04 lower.
So I'm a somewhat confused, as I seem to have the latest version as per it always asking confirmation about new coil, but it still seems to underestimate the base resistance, which from previous posts appeared to have been fixed in this firmware. Wish there was a surefire way to check the version!
That's a pity I won't be able to do any further investigation for a while, hope I'll get some new insight by reading this thread...
EDITED: My NP comes at 70

So my VS 60W from FT has a default NP at 70, it locks resistance (as far as I can tell), it asks for new atty after wake-up but reads 0.04 too low...!!
Hum!
Well this is very confusing. I suppose we only have @Shogun1024 's single measurement (0.14 versus 0.15 reference point) to say resistance is improved.
@Shogun1024 do you think you could do some further tests, comparing resistances on your new Zero versus other mods and your ohm reader, at different ohms levels? Eg 0.10, 0.20, 0.40, 0.60?
Below are the figures @balazsk got with his device, can you see how yours compare?
@balazsk could you confirm if your mod has the New Atomizer Up/Donw question? I was assuming not (and so it is 'batch 1'), but if it fact does then that's different and you have already confirmed for the new batch.
@TheotherSteveS and @ndb70 - is it always -0.04? And what base resistance is that for? Will it read 0.14 as 0.10 and 0.54 as 0.50, or does it vary across the range?
