Sdna and dna75 chip do the exact same thing the dna 200 drove
Me nuts on.

What is the mod resistance for each of your builds? How did you measure it?

In device monitor is room temp close to real room temp...have you tuned the case settings or run the analyzer?

When I have issues similar to what you describe, it is typically an incorrect mod resistance value.

Interesting thanks. I'll check that. No was under the impression the sdna settings were widely considered correct. I haven't run he analyzer. In the DNA 200 mod I was working with the mod maker told me if I changed any of that he'd good my warranty. I suppose it could
Be possible that around the flood ac could have something to do with jt but the room temp
Remains relatively constant.


I'll connect it to the PC and post back later today. On the 200 both the mod maker and evolv had differing ideas. When evolv saw the recorded values they concluded the 529
Was the issue. Mod maker refused that. But with it happening on two subsequent mods it makes sense that either environment. Is he issue or a series of bad luck with values.


Thanks for the help. I'll
Run the tools (I'll need to refresh myself on the process it's been a while) and get the results posted here for comparison to other sdna mod owners and general info. .

You have an interesting and annoyingly odd issue happening, I hope to see a resolution.
Mod case values, especially mod res would be a great, simple fix. Fingers crossed.

But...

Well at an advanced age one should realize that opening a post with a flat WRONG is quite rude. Whe. Another is simply trying to offer help and states it's a matter if memory and may be mistaken.

I take it that means you're young enough to proofread your posts. They're horrendous.

Take a half-step off the soapbox, eh?

The same argument for lacking acronym knowledge should apply to manners.

Physician... heal thyself. ;)

I don't find Stainless reliable at all frankly of all the materials I use. None of the grades. On any device. Compared to nife 48 and nickel it's way off.

LOL... Wut?
Let's not pretend this is rocket surgery.

Sdna and dna75 chip do the exact same thing the DNA 200 drove
Me nuts on. So I have to figure out what I am doing wrong because I can't believe more people wouldn't be annoyed by this.

Build rta
Mount with both devices at room temp
Fire and resistance sets say .35 vape a few times to break
In coil

Cool back down remove tank. Fire mod no atomizer with both room temp
Mount again.

Fire. Resistance sets to slightly different due to wire settled whatever. Call it .38. Both tank and mod have been resting five minutes.

Vape away with temp setting at reasonable level.

Stop using mod. Allow To Sleep with atomizer attached.

Press fire button to awaken and resistance has dropped drastically. Is now .30 requiring 100 more
Degrees for same vape.

Allow to cool 5 mins. Remount. .38. Vape normally


Every time a current DNA chip
Sleeps my resistance drops through the floor. Happens on every tank. Different materials. Dna200 DNA 75. Etc. the only solution is to vape for a second on first mount and allow the mod to cool and register then lock ohms.

On the DNA 200 the lock was irrelevant. I could lock at like .38 and if it slept it came back at .3 still locked.

It's such a drastic difference after sleep it throws everything off. And it's not right, the same tank registering .3 after sleep on the DNA shows .35 on ten other mods. I need to see if the resistance lock is respected now through sleep mode. It should be respected through anything. Unless I unlock it should never change.

So the conclusion for me is that sleep mode causes some weird analysis and low resistance readings. Been were delaying with builds in the .05-.4 range these changes can drastically affect the vape. 100F+ changes necessary to get it output.

So where's the error here. If I am waiting 2-5 mins for my build to cool why would the mod register it on first mount .08 higher than it does after a long rest and deep sleep? Why would it register lie after sleep when every other decide I have reads it as expected?


I must be ding something writ but it's not build related. There's no short. There's not an issue with nife48 or nickel or stainless. Hell stainless I could understand.


Super confused and frustrated this is still happening. And feeling crazy nobody else seems to have this issue.
It sounds like what's happening is when you take the atty off and hit fire then screw it back on the atty hasn't completely cooled. So it's locking in a higher resistance (warm/hot). Then as it sits overnight, it's refining to the correct cold resistance. If you fire it and repeat the procedure you are again locking in a warm/hot resistance.

If you want a warmer vape turn up the temperature. If you think the mod is refining to a resistance that is lower than the build, check what your mod resistance is set to in Escribe. I believe the correct number for the SDNA is .002ohms

Cheers,
Steve

That was my first thought too. But it happens on any mount. 5 mins. 20 mins. It's cool for sure when mounted. - maybe the initial

The increase required sometimes causes the temp To exceed 600F to
Get the same vape that was happening at 400F. It can fluctuate that much. Other times it can chaise a setting that was fine (475F) to immediately char the wick. If it was is it off by twenty degrees wouldn't have an issue. - as it works now if I fail to Remember the old value and compare it to The new I can wind up when a ling full of combusted material rather defeating the purpose. :)


Alright I haven't used this mod/tank I. Two hours now. And it's asleep. So it should register the correct value after awakening with the fire button right ? For a mtl tank vaped at lower temps with a 6-8 wrap nife 48 28 gauge build. I wouldn't think
Cooling after two or three draws would take longer than five minutes.but how long would you take to consider something room
Temp?

I'll run some recordings and see if I can post some screenshots. Maybe those of you with a lot more experience with the manufacturer and software can find the issue. I'll do the case analyzer first

I'm vaping at 375F right now with a reusable reading which matches two sx mini m class mods. Boxer mod. Provari radius. And 510 build station 510 and alligator clips.


Maybe you can tell me. At 475F we would
All Agree there should be significant vapor production? It was .35 after rest and sleep. 375F was comfortable. Rested ten mins. .3 525F + needed to try and get he same vapor.

So that's he symptom. I'll get to measuring.

Out of the box the SDNA75 resistance is set to 0.0016 by DJSLB, the reviewer that helped with the presets and wrote the manual. I got 0.005 when I ran the test using a 99% copper 510 plug.

I see. That's not much of s difference. I'll ice it s shot and see thanks a lot. I need to figure out the plug

There may be some issue with some DNA75 doing this. That modder I told you about is no newb and he had the issue as well.

Just got my VT75 Nano. I like it a lot. Might be my favorite mod now.

The only issue I've had with my new HCigar VT75 NANO is the horrible battery cover. Read it elsewhere and experienced it myself. The fact cover is thin, and the threads TINY. Hard to line up the cover and threads properly. At least on mine, I keep cross threading the cover no matter how careful I am. It gets stuck, and I've had to use pliers to get it back off and start again. I'm getting a 2nd battery cover sent to me in hope it's not the threads on the mod. Be careful!

Sounds like the Nano has the same threading. Luckily, I charge my mods via USB so not really an issue for me. I've been charging all my DNAxxx mods via USB for over 2 yrs with no issues.

Yeah, I just edited my post to indicate "NANO", I don't own the first, larger model. It's a shame they made the cap threads so thin, maybe soft aluminum, not sure.

Does anybody know of a longer data cable to use with the evolve dna 75 chip and what it is called.The one that came with my smy sdna is only about 8 inches long and driving me crazy! I did look but it is confusing with data 5 pin etc.Any help would be really appreciated!
Any good quality USB 2.0 cable will be fine. I like Anker for aftermarket USB cables and I use a 3' for escribe.

Amazon.com: Anker [5-Pack] PowerLine Micro USB - Durable Charging Cable [Assorted Lengths] for Samsung, Nexus, LG, Android Smartphones and More (Black): Cell Phones & Accessories

They sell in various sizes and packs so poke around and see what you want/need.
