John Posted July 27, 2015 Report Share Posted July 27, 2015 Bern if you use atomizer analyzer on a cold coil, what does it read? What does this coil read for resistance on other mods? 350 is pretty low for most tanks, try it at 450 and seeIt is clearly reading some change in resistance and it is reading a temperature, so either your cold ohms is wrong, or your juice doesn't do anything at 350, or the TCR curve for your material is wrong. Is this Nickel 200 wire or something else, like a titanium? What atomizer? Can you set device monitor up with just power, temperature, cold ohms and live ohms, and then hit the record button and post the CSV file of a couple puffs? It is detecting temperature control (or it would fire at your 25 watt setpoint rather than temperature limit low enough you aren't getting vapor) so this should be totally possible to diagnose.

Bern18462 Posted July 27, 2015 Author Report Share Posted July 27, 2015 It reads .07 on everything I put it on .. I am using ni200 wire from protovape.... Atomizer is a mad hatter rda , doge rda , and a zephyrus rta... What's in the graph I believe that's all I have is power ... Cold ohms ,ohms amd temp but after I get off of work I'll try and post that file with the settings you need Link to comment Share on other sites More sharing options...
John Posted July 27, 2015 Report Share Posted July 27, 2015 You have battery voltage too. It isn't hurting anything, but the less items you're graphing the faster it updates. The .csv file should let us see exactly what it is seeing as it fires. Link to comment Share on other sites More sharing options...
Bern18462 Posted July 27, 2015 Author Report Share Posted July 27, 2015 OK awesome I get off in an hour then I'll post that file Link to comment Share on other sites More sharing options...
John Posted July 28, 2015 Report Share Posted July 28, 2015 Zip it then upload it. =)But five seconds at 35 watts-ish and you don't get vapor? Link to comment Share on other sites More sharing options...
Bern18462 Posted July 28, 2015 Author Report Share Posted July 28, 2015 i dont know what the hell i did but now it works on and off .... n ok ill try but im no computer wiz so i might not be able to do it ha ha Link to comment Share on other sites More sharing options...

John Posted July 28, 2015 Report Share Posted July 28, 2015 Okay, I'm seeing 4 puffs, with a cold resistance of .092, a hot resistance of .162, which is 350 degrees or so, and 35ish watts of power. That all seems pretty normal. What were you getting out of it for these four puffs? Link to comment Share on other sites More sharing options...
Bern18462 Posted July 28, 2015 Author Report Share Posted July 28, 2015 i used the same coils as before when i STarted this thread and they were at .07 ohms and now all of a sudden there at .092 and it vapes???? idk what happen but i got some good vapor off of this one ... but it still dont recognize my ni200 wire i always have to change it temp ...

Ken Nutter Posted August 19, 2015 Report Share Posted August 19, 2015 "Help me Obi Wan Evolv. Your my only hope... " OK so temp mode has been awesome until a cpl days ago. Now I keep getting burnt/hot hit temp control not kicking in and throttling back wattage. I've tried different atty's with both NI and TI. I've turned on atomizer analyzer and wiggled the coils around it stays stable. When I turn on device monitor it don't show temp of last puff or anything. Firmware is updated. Tried Hard reboot. Any ideas???? Link to comment Share on other sites More sharing options...
Bern18462 Posted August 19, 2015 Author Report Share Posted August 19, 2015 Stupid question but are u sure its in temp mode I did that a couple times after a hard reboot? Link to comment Share on other sites More sharing options...
Bern18462 Posted August 19, 2015 Author Report Share Posted August 19, 2015 Also is yours a custom box you did or did u buy it from a company complete Link to comment Share on other sites More sharing options...
Ken Nutter Posted August 19, 2015 Report Share Posted August 19, 2015 Positive I'm in temp mode. It's an Opus Link to comment Share on other sites More sharing options...
Ken Nutter Posted August 19, 2015 Report Share Posted August 19, 2015 Even set temp all the way down to 250°f and turned watts up to 122... Link to comment Share on other sites More sharing options...
Bern18462 Posted August 19, 2015 Author Report Share Posted August 19, 2015 Mine was doing that for a while but it was one I built and had to re check all the connections but in your case if you open the box it will void your warranty right Link to comment Share on other sites More sharing options...

Dampmaskin Posted August 19, 2015 Report Share Posted August 19, 2015 I've had a perhaps related issue. When building a TC coil with a lower TCR than Ni200, and boosting the preheat to 200W and "Hard", the DNA 200 seemed to pop out of temp control. The temperature curve disappeared from Device Monitor, but I could still see the resistance increase as usual during the puff. I couldn't regain temperature control - and the temperature curve in Device Monitor - until I lowered the preheat.The wire was 30ga Kanthal A1 twisted with 30ga Ni200. Something like this:[CODE]"Temperature (degF)","Electrical Resistivity"-94,0.650907889194574268,1212,1.3261584754547935572,2.4572348525753145662,2.7121364826264474752,2.938747849424949842,3.160562053313862932,3.375997699618637[/CODE] Link to comment Share on other sites More sharing options...
Bern18462 Posted August 19, 2015 Author Report Share Posted August 19, 2015 Id say a connection or something idk have you droppe it lately or anything... Maybe post a graph on here so everyone can. See whags going on Link to comment Share on other sites More sharing options...
Ken Nutter Posted August 19, 2015 Report Share Posted August 19, 2015 I don't see anything inside that yells hey this is messed up. Looks all solid. Link to comment Share on other sites More sharing options...
blueridgedog Posted August 19, 2015 Report Share Posted August 19, 2015 When this occurs to me, it is typically atomizer resistance that has crept in (I start with a .23 coil, after time it reads .35 and vapes hot as can be). I typically have to adjust the atomizer screw so that it makes "perfect" contact with the 510 (i.e. enough pressure to take up the thread slop in the atomizer center post). As a rule (for me) I like to know what the coil should be, so if the chip starts displaying something off, then I can avoid the "boom" event of too much power because it things it has higher resistance to account for. A good atomizer and a solid high pressure 510 solves most of these resistance migration issues.I have one atomizer that works like a champ on the evolv 510, but can't be used on others. There is just not enough pressure on it. Link to comment Share on other sites More sharing options...
Ken Nutter Posted August 19, 2015 Report Share Posted August 19, 2015 I've tried 3 different atty's. So I fing that highly unlikely. Link to comment Share on other sites More sharing options...
Ken Nutter Posted August 20, 2015 Report Share Posted August 20, 2015 What the crap its working again now... That's awesome and even more confusing... Let's see for how long though... Idk maybe it was just missing kanthal. Thanks for trying to help those that posted its appreciated Link to comment Share on other sites More sharing options...
