.06 is not a very large difference. You may find a replacement unit to be further off. I now longer own a volcano, so I can't give you a number. For anyone else that owns the SDNA75, he is a paste from a post I made a month a go in the Escribe forums:
These SMA SDNA75 devices were setup software wise by DJLSB, a very knowledgeable reviewer. They come with wire presets, that I have since changed. However he did include device resistance settings. I can't confirm the case thermal numbers as I have not run those tests. The only one I can test is the the main device resistance in "Atomizer Analizer", using the solid cooper 510 plug that was sold through a member on this forum, look in the DNA200 thread. You first set the resistance to ZERO, upload the settings back to the device, then run the test.
The original value that has been preset on the device was: 0.0016
My test showed 0.002 on 3 of them, and 0.003 on the 4th.
This under Escribe version 1.2
There are other ways to short the 510, if you don't have this custom copper plug.
My buddy has the copper plug and he measured the Lavabox MDNA 75 at .002 ohms. I would go with that. No higher than .003 ohms.

Not to be disagreeable but while 0.06 ohms might not amount to much with Kanthal coils it is a huge difference say if one were to be using dual Ni or the like. The mod resistance needs to be checked to make sure it falls 0.006Ω or less, any more and I'd be looking for why.
I only wrote as I went through this. I bought a couple of Target Mini mods. I found the exact same .06 ohms difference when reading known ohm coils, as well as compared to other mods, and USA OHM meter. Since PBusardo did a review on these, I wrote him on you tube, wondering if I should return it. I specifically told him I was doing TC, and thus my concerns. He responded:
"I'd keep it and adjust accordingly. The difference between .50 and .44 could be a spec of dust on the thread, the alignment of the planets, or the color of your underwear, a very small number."
You may or may not respect his opinion, but Volcano might agree, find a different reason to return it, just don't be disappointed if it does not solve the issue. The only device I half trust for readings in the hundreds is my USA ohm meter, and I'm greatful when my mods agree.
Here's an atty with dual Nife70, cold ohms is less than 0.07 ohms, I'm pretty sure a 0.06 ohm error would be for lack of a better word "unacceptable". They say a pictures worth a thousand words, well here it is:
a .06 ohm offset on, let's say dwcraig1's .059 ohm TC coil (cold base res), would destroy the ability of the mod being able to do TC....at all.
a .06 ohm offset might not be quite as noticeable on a non TC coil such as kanthal or ni80.

Thanks for help guys! I too think .06 is a big difference especially considering all my other mods agree that the resistance is .60 not .66 (tested it on each just to see). Think I have "fixed" the issue by setting the mod resistance to .06.
The biggest disappointment is that I haven't heard a lick from volcano yet.

I'll give PBusaro a break on this, as I was inquiring about the .6 ohm difference I was seeing on the Target Mini mod, which cannot be connected to Escribe to change the mods base resistance. And the coil I was noting, was a .50 ohm coil reading at .44 ohms, that's a lot different then comparing to a .06 build. The lowest prebuilt coil I ever see is a .15 ohm Nickle, but I do run a few SS Notch coils at .25 ohms, and a .6 ohm difference could make a small difference on those. Most of my own builds are way above .06 ohms.
As far as volcano, I had a decent experience with them, but no longer own any of their products. Good luck.

Well not only a non adjustable mod. But honestly the coils themselves are spotty at best. I have had upwards of a .05 variance and several subohm coils. Also my eleaf istick 50w, would be upwards of .2 off compared to any device. Obviously non of these mods were meant to be used in sensitive situations.
Honestly .06 is a pretty large deviation for a DNA device. Specially .06 high. I always ran into an issue on a couple DNA's that would be maybe .01-.02 down. But the heart beat check would resolve that after a while of it sitting cold. I would suggest that there is a loose connection to the 510.
In my case the coils ohms only read different on the Target mods, they read correctly on everything else. They were both returned for different reasons. One had a wobbly 510, and the other had a problem I've never seen before, the internal battery was DOA, I would charge it, it would work for a short time, then suddenly die. Maybe a bad day in the factory. I don't expect these cheap mods to perform like my DNA's anyways.
If you want to make a tool for grounding/shorting the mod's 510 to set mod resistance an old cartomizer or 510 to 510 adapter will do nicely.
Remove the innards/grommet and fill the end with solder, it works just as good as the copper tool.
Not sure if it was in this thread or one of the other DNA threads but I was asking about this weeks ago but never got a reply, so thanks for posting that.

The picture was taken before I was finished with it, it's a bit long. I sanded it down some.Not sure if it was in this thread or one of the other DNA threads but I was asking about this weeks ago but never got a reply, so thanks for posting that.

I'm not in the US so no free shipping for me, shipping to me doubles the price. I'm aware of the British version too but that comes down to around about the same price for me including shipping.
I might take one of my mods to a very well assorted hardware store to see if they have a copper bolt with matching threading though, although I can't imagine someone hasn't already tried that so I'm not holding my breath.
Would brass be ok too? That might be a little easier to find.
I live in the US and I still bought the UK version because it is more pure copper than the US one. Plus it has that cool laser etchings (I think it is laser anyway).
Finding a bolt is one thing, but finding those fine threads would be a bit tough. Yes brass would be ok. As some use solder and that wouldn't be as good as copper or brass.
