[Mod Resistance]

Well here is what's going on, with all the 250 boards and all the 200 boards with 1.2 SP? software Atomizer Analyzer will not read below 0.007 ohms. So if it displays down to .007 then throws up a "?" it's .007 ohms or less.
On the earlier firmware it wouldn't read below 0.002 ohms.

Could you please tell me what firmware can let us read below .007 till .002? I have DNA 250, escribe 2.0 sp3 and still not reading under .008!

Thank you, 

Could you please help me find the thread or some keys words to find it?

Also, a lot of other people CAN read 0.005 without problems, so... I don't know if it's some batches hardware issue or a software issue

Thanks

[Vt box 250 - Can't read under 0.008 ohms]

Hi everyone,

My device can't read under 0.008 ohms. I noticed this while shorting atom to know my mod resistance. No matter if I change atomiser or if I change wire (for instance I used a thick copper wire) but when I attach it, it start to read for example 0.011 and while I screw it began to go under and under, while the connection become more stable, until... 0.008 and then only "?". Picture attached. Please help!

Shod I try to check 510 connector or maybe it could be a fault in the board?

 

Thanks

Very interesting answer, thank you very much!

I have some cheap powerbanks that do that when I pull 2 A +, some seem to reset, it could also be the 250 lowering charge power when it gets hot, put the board temp on the charge screen to check for this and see if it drops at a particular temperature.

 

[Vt box 250 inconsistent charging - random usb current drop down and display turned on and then idle very fast]

Hi everyone,

Got my 2nd DNA device (vtbox 250 fullymax 1500mah 3s, 25c) and I noticed that while charging, the device turn on to active mode randomly, and this is happening many times during the charging. In that scenario, USB current drop down to raise up again very fast, as like as I removed current source. I also noticed that this doesn't happen while charging to my PC at 1A, but only with a 2A wall charger. Tried to change it with another 2A charger but nothing changes. I confirmed all this situation by monitoring the device with escribe: 1A current, usb voltage sometimes go down, but in this case (PC charging) my display won't turn on from idle state and doesn't show usb current drop down. 

Anyone can help me to understand is this behavior is normal for DNA charging mode? Thanks

Hi @James, thank you for support. 1) My mod is a tugboat and I found someone who told me to set mod resistance to 0.007 and that's what I did. But my mod came to me set with a "zero" value. So I trusted that guy and set it to 0.007 at first day I received it. I'll search how to run this test, anyway. 2) yesterday I thought that maybe my .12 ohm resistance was too low, so I built a looped wire of 20cm (no wraps) of SS 316L with a total resistance of .90 ohm to be sure that my too low resistance was not causing the issue, but with no good results. 3) My SS wire came from zivipf.de a German well known wire as one of the best on the market. Also asked around discovering a lot of people are in trouble with SS. Also, my zivipf wire is going really flawlessly for someone (304L,316L,317L) but not for me, so at the moment I was not able to say what exactly is causing this behavior This weekend at vapitaly expo I'll get some 304 SS to try... Let you know and thanks for helping me

Same issue here, man! Don't know what to do! Cleaned threading, brushed atom Pin and rebuild it again. No way to work for it! Just hoping for un update or something or waiting for Santa's/Jesus/Allah/Gamesh etc...

Same story here... With 316L SS 0.60 first attempt and 0.50 second attempt, 6 wraps per coil - inconsistent temp curve staying at what device monitor says. No issue with nichel on the same atomizer. Later I'll try to use another atom and see what happens. To simplify tests o don't wrap and don't wick my coil just letting the wire looped and check device monitor while pulsing and firing. It just does not work. Downloaded csv files but did not change preheat and let it at 80 °C, how it wat set before on ni200 Check this pic
