Enigma

And for that reason alone brings me back to why I'll just continue with wattage, I'm a chainer with one mod, so waiting 30 mins till there both happy won't happen. Still even if the device was cold as well as the RTA this shouldn't have any effect on electricity passing enough metal to read resistance.

Sometimes if I forget to measure the resistance manually it will assume I have a new coil and ask to use new value. As for a cold mod, that never happens, mods kinda in my hand all the time. In most cases one RTA is finished, so I remove it, add a new cold RTA, read the resistance and keep going.

Oh on a side note I just changed RTAs and this one has a N80 fused coil, cold read was 0.695, 2 puffs and measured again, yep you guessed it, even with N80 the resistance is dropping, already dropped to 0.654, wtf now it's jumped to 0.713 FFS.

Yes and no, the measurement taken is locked in when measured, so Replay still would fire, and yes TC should just not fire if it falls enough below the original reading. Also if it say reads at 0.5 and still fires because of the lock then the temp degrees and cutoff points would be wrong, ie it could be set at 150 degs C and still burn your throat out thinking it hasn't even reached 150 yet when the real resistance is actually 0.3 or something. Soooo many things wants to burn your lungs out when it comes to TC lol.

Thanks for the offer but a temp profile has no bearing on resistance, infact no temp profile in existence would be usefully if the resistance is measured incorrectly. I have tried multiple CSV from steam engine, the stock standard ones in Escribe and a v4 one made from someone ages ago. Haha my Google Foo is quite strong when I'm trying to fix something. As for SS316L, well that's because in Australia that's pretty much all we can get our hands on, I don't want Titanium for health concerns and Nife always seemed like a pain.

I dont actually use tanks, only RTAs and RDAs, haha I didn't think cartomizers existed anymore. As for the tanks I tested I opened, cleaned, move, soaked, changed coils, moved coils, changed screws, the lot, this was over 5 different tanks as well. So unfortunately not relevant in this situation.

At this point I've given up on Temp Control and Replay, far far to much a hassle to get anywhere near a stable vape. I'll just use the DNA mod in Wattage mode and N80 from here on in.

Yes that's correct. For some reason it's like the cold resistance needs a short fire to actually read the proper resistance after it cools down again.

So I have no idea what was wrong with it or possible fixes, the shop I sent it back to just simply refunded me. The very worrying trouble I'm having now is the same issue is starting to present it self with my new Odin Mini (DNA75C), it was perfect the first week and now it's doing the weird resistance reading the Centaurus was doing.

Well it's only 2 weeks old so I certainly won't be opening it or fiddling with adapter's, I'll send it back and let them deal with it.

Gave that a try this morning to see what was going on, as expected it did pretty much what i was seeing when just doing a simple resistance measure. I did notice how ever that there could be a 0.02 to 0.04 difference in resistance depending on how much the RTA was screwed on.

The trouble is I don't know what the correct lower resistance is since it isn't detecting it correctly.

Yeah I thought locking may help for about 2 minutes till I realised locking it at a resistance higher than its base would just screw up the temp settings. Basically it would always think it was at a much much higher temp always. Also the device wouldn't fire because it would detect the resistance lower than what was locked.

I've noted the resistance going about 30-40% lower than the cold reading, definately enough to screw up and temp control. Thinking back I'm pretty sure I've even noticed n80 coils resistance change, I never really cared though simply because it was in power mode.

First up i have been vaping for about 8 years but this is the second DNA device i've owned (Therion was first). Ok so the jist of the issue is when i attach a cold RTA and measure the resistance for example it will read 0.4, ok so i fire it and it increases, this is normal, at this point it gets frustratingly weird. If i leave the device alone and not fire the resistance naturally lowers as it cools, the issue is the resistance will now drop lower than the initial cold resistance. Naturally if i read the cold resistance in a temp control profile it wont even fire, doesn't say atomiser error or temp controlled, it just wont fire. Of course if i use it in replay or power mode it does fire. Thinking there must have been a setting error i loaded the default configuration for the Centaurus but still had the same issue. I then tried the RTAs on an Ehpro Cold Steel as well as an old Pico 75w that has Arctic Fox on it. Temp controlled worked as expected on the Pico and the Cold Steel didnt have issues detecting the resistance. The coils i have tried and all resulted in a dropping resistance are all SS316L (26ga, 28ga, 26ga twisted, 28ga twisted, 28ga fused, 26ga fused, you get the idea i have tried a lot) each have been tried as contact or spaced. RTA used in testing, HellVape Destiny, Augvape Intake, Dovpo Blotto. The resistance should never drop lower from its cold reading but here it does every time with a temp sensing wire, at this point i can only assume it has to be the device since i have never had this much an issue with temp control before.
