DjMadness Posted January 11, 2016 Author Report Share Posted January 11, 2016 I seam to be having troubles getting temp control to work as stable as possible.When running in temp mode (i am using csv from steam-engine for stainless steel 316), the resistance jumps up to over 1 ohm when my resistance is at 0.44 cold.after it reached over 1 ohm in temp mode i quickly activated watt mode and it states 0.5 ohm's live, going back to temp mode its over 1 ohm again.Something's wrong and it does not sound coil related, more software related, could someone help me with this ?edit i have a wismec dna200 Link to comment Share on other sites More sharing options...
Havensal Posted January 11, 2016 Report Share Posted January 11, 2016 It sounds more like a hardware issue to me. Make sure all you connections are tight and that your atty is tightened down properly. Also make sure your 510 pin is clean and dry. Link to comment Share on other sites More sharing options...
Spector NS5 RD Posted January 11, 2016 Report Share Posted January 11, 2016 what type of rda u using? have you gone into atty analyzer in escribe and checked you atty's ohm stability? im running 316 in a subtank mini with .00092 tcr. and it works ok. make sure all your connection are secure, a decent atty for tc, try a hard reboot, make sure your mod resistance is set correctly (.003 is what mine is). turn your preheat off. lock your resistance with a cold atty.

DjMadness Posted January 11, 2016 Author Report Share Posted January 11, 2016 connections are down tight, if i tighten anymore it would probably break the wire.The analizer states that its flucturating with 0.001 (quite normal considering its putting power through the coil)The resistance only goes unstable in temp mode, not when tc is disabled.

Havensal Posted January 11, 2016 Report Share Posted January 11, 2016 I have noticed my SS TC goes a little crazy at the temp limit. When looking at the chart the temp goes up smoothly until it reaches the set temp and then bounces up and down radically. It vapes fine, but the chart look all zig zaggy.

VapingBad Posted January 11, 2016 Report Share Posted January 11, 2016 Try a higher temp, it will stop treating the coil as temp sensing if it does not increase temp by at least 150 degrees F in the first second, I know that your temp is greater than that + room temp, but it may get you closer to finding the solution. Also I would lower the wattage so when this happens you are not getting that much power. Link to comment Share on other sites More sharing options...

I increased the tempreture to 200C and reduced the resistance manually to 0.42Ohm's and it seams more stable now. Stainless steel seams rather unstable for it to need manual adjustment after coil change. for this i mean ie if i am forced to change coil while at work i would be forced to configure via escribe before its stable.(i did dryburn and leave the ecig for approx 30 mins before locking the ohm's but adjustment was still needed) Link to comment Share on other sites More sharing options...
DjMadness Posted January 11, 2016 Author Report Share Posted January 11, 2016 Some sort of menu ie 4 clicks on fire button while locked to manually change resistance of coil would be useful. Link to comment Share on other sites More sharing options...
DjMadness Posted January 12, 2016 Author Report Share Posted January 12, 2016 update:there is still high instability with the resistance under temp control, however this seams to only happen when the mod is cold now.after waking up this morning temp control did not work, so i vaped in wattage mode (thanks to its stainless steel it's possible), once the mod got a bit warm it started working again.does the chip use board temp or "room temp" to calculate the tempreture in some sort of way ?

VapingBad Posted January 12, 2016 Report Share Posted January 12, 2016 The res changing when cold in the morning is almost definitely a connection issue, I have had it a few times and tracked it down to coils screws not being tight enough.

DjMadness Posted January 12, 2016 Author Report Share Posted January 12, 2016 I'll try and make some new claptons when i get home and remove the wrap where the connection is to be made, maybe that will help (its not like the clapton is going to conduct electricity.)do you recomend any specific resistance to go for ? or would i be fine with fused claptons ?

VapingBad Posted January 12, 2016 Report Share Posted January 12, 2016 No sorry, I don't regularly do Claptons or ss. Link to comment Share on other sites More sharing options...
HugeEgo Posted January 12, 2016 Report Share Posted January 12, 2016 Go buy some 430 SS. It's TCR is higher and it generally is less of a PITA to work with. Link to comment Share on other sites More sharing options...
DjMadness Posted February 3, 2016 Author Report Share Posted February 3, 2016 update, i got it working.it was actually the positive pin causing issues, sometimes it screws it's self a little bit lose.happened to me a couple of times, probably due to it being a clone (velocity rda, original is not easy to get atm)I've been using TC without issues for some time now, this device really shines compared to other devices, i can't imagine what evolv's next chip would be capable of, but as long as it has the capabilitiies as the dna200 they have me as a customer (specificly the triple 18650 part and temp curves ) Link to comment Share on other sites More sharing options...
