I believe that's on the negative, between the battery cap and atty base. Bad ground on caps.

But the battery cap and negative side of the 510 are connected together. How could you ever read a voltage across these?
Focal Getting SXK 60W Flask Samples in 48h - Full Stocking Surely To Follow?!
Second email from her:
I was informed by our product department staff that first batch of SXK VF 60w (Sample order) would arrive in 48 hours.
If there is any further news, i will keep you informed
Thanks for your suggestions!
Best Regards,
Doris

Second email from her:
Thank you so much for your pre-caution. [I asked her team to thoroughly test all VFs, especially Black, for battery thread gunk / grounding issues.]
I will make sure that they have a thorough test and will also send some pictures if possible. If possible, i will reserve for you guys who gave us recommendation.
The price would be around $71 based on the price that SXK offered. You know, all of products we got from SXK are almost similar to FT's listed price which is a shame, that was why we didn't stock it at the beginning. I was recommended by some vapers from ECF that the price was acceptable.
I wish you won't have the impression that Focalecig is ripping vapers off due to higher price because i know the price difference is so apparent.

The battery cap has a good connection to the batteries negative but the caps threads aren't passing it to the chassis of the mod. So when a volt meter is in a series between the cap and 510 you can read the voltage drop. A perfect ground would read 0 volts. That 1.7 volts was just from powering the board, not firing the coil i believe.

Doris just mailed: They`re getting a sample order of 10 pieces in the next 2-3 days
Upps: TheBloke was faster ;-)

Yeah, received it too.
Great news! I hope she will reserve the few they're getting for the people who were asking her about it. They've probably ordered 5x silver and 5x black

I probably should know the answer to this but I don't so i will ask.
Do all of the SXK temp control flask have the low resistance read problem?

She just sent me a second email - yes she will reserve for us. Edited my post above to add more info including estimated price ($71)
She also said "If you need me to reserve one for you, please just simply reply email in 12 hours after we list it
" - this applies only to those of us who emailed her already of course
Every mod with the new SXK chip has this problem, to our knowledge.
Well, the odd person here or there has said they find smaller deltas or provides one reading that seems on-par; but everyone who has tested it thoroughly against reasonable benchmarks has found the issue, across all three SXK mods (VF silver+black; VS rDNA; Zero of multiple types). So I am inclined to ignore the occasional 'no issue' finding as being poor testing, given the volume of confirming findings from everyone else with an SXK chip.
As @dwcraig1 has pointed out you have resistance & voltage drop from battery cap to 510 ground
Cleaning them threads more should resolve this
Aluminium mating to a dissimilar metal is not ideal but with clean threads it should be fine
Glad you found the issue & on the way to resolving once & for all
Verifying using one of those atty ohm checkers carries little to no meaning to me, I believe that's what some used to check with.
I imagine some are OK and others, well are not.
Agreed, the occasional 'good' reading is going to be user error or equipment error (or both)
For reference again, for anyone who missed it before, the main set of figures I currently refer to are against a reference micro-ohm reader, tested by @balazsk, of a Batch 1 Zero I think it is. These match my findings against the other mods I can test against (I do not have reference micro-ohm equipment.)
Real Ω | SXK RΩ | Differ | Diff %
1.78 Ω | 1.53 Ω | 0.25 Ω | 13.8%
1.27 Ω | 1.07 Ω | 0.20 Ω | 15.7%
1.08 Ω | 0.92 Ω | 0.16 Ω | 14.8%
0.90 Ω | 0.75 Ω | 0.15 Ω | 16.7%
0.60 Ω | 0.50 Ω | 0.10 Ω | 16.7%
0.42 Ω | 0.35 Ω | 0.07 Ω | 16.7%
0.30 Ω | 0.24 Ω | 0.06 Ω | 20.5%
0.20 Ω | 0.14 Ω | 0.06 Ω | 28.6%
0.16 Ω | 0.12 Ω | 0.04 Ω | 25.9%
0.10 Ω | 0.06 Ω | 0.04 Ω | 40.0%

Hm, not sure if what she's saying is true Bloke.
I mean, you'd already posted earlier that when you order 5 from SXK, it would be around $51 including shipping to Europe/US. Shipping within China is much cheaper of course and I'm sure if they order say, 250 units, the price will most certainly drop.

That occurred to me too, however that $51 has no profit for Focal and no taxes and no CS cost and no built in cost for returns and all the rest.
You're right that the $51 surely goes down for more units, but maybe Focal don't sell as much as we think or at least at the moment they're not able to guarantee enough units. And/or maybe SXK have preferential suppliers and don't discount much for others - or maybe they just don't like Focal for some reason.
I'm willing to give her the benefit of the doubt at the moment - if they could have stocked it cheaper earlier, why wouldn't they have?
And $71 remains a very good price; less than the $76 I paid for my Waidea, which 3FVape are still selling it for.
I'm referring to those few that said they had no low resistance problem may have used an inaccurate ohm checker to come to that idea. You'll get no disagreement from me, it's the chip as far as I'm seeing it. (also)
Maybe what we need to do now is contact 3FVape and get them to stock it - they already sell the Zero for $58 which is an FT-like price, so presumably they get better prices.
Though perhaps they've deliberately decided not to due to patent worries, and/or so they can first shift their Waidea/Kangxin flasks.
Worth an enquiry still; though not from me, we didn't part on the best terms after my Waidea incident

Sure, it's still a great price for such a unit but I've become accustomed to take their (Chinese business people) words with a fairly large grain of salt
I don't think their price will be much more than $47 shipped per unit (when buying 5 units within China). She's saying the price they have to pay is "almost FT listed price" which was something like $59 so already $7-$8 higher than the quote you've received from SXK.

Now there nothing wrong with using one of those as long as it's checked for accuracy against other "things".
Mine is good on some atties and poor on others, I'm think about putting a good 510 socket in it with real wires.
I had the same idea because mine is basically pointless - I made a mistake and bought one without its own 510, it has an Ego connector with adapter and the adapter gets stuck to the atty unless I screwed it down super tight on the device. And when I did that, the ohms readings were off the chart - 1.0Ω on a 0.3Ω coil, stuff like that.
I bought a cheap spring-loaded 510 from China, and also a cheap single-piece silver 510 of the type that normally goes in such devices, and I also still have my FDV v3 Shorty I never put in the Waidea. It's "on my list" to put one or them in the ohm reader to try and get some sort of accurate device, but not even started to look at it yet.
