I don't think anyone understands what you are asking! Maybe give us some more info?!?
lol.. ok wat i wanna asked is the difference between devices such as ipv3 li(able to locked in resistance) n snowwolf(unable to lock in resistance).
on my 1st attempt on TC with an ipv3 li, i encountered this "dry coil, no liquid" problem after taking out n screwing back the atty to refilled my juice. i realised that's becos because i didn't locked the resistance. so what happened if i were to use a snowwolf to do the same thing? since snowwolf doesn't support locking in resistance, will there be a problem if u reload the atty?
My understanding is this. You need to put your atty on at room temp so that the true resistance is known to the mod then lock it so it doesn't change when you put the atty back on. If you were to do this on a snow wolf, the atty could be warm when you put it back on, which would affect the baseline resistance, therefore throwing off your tc. It wouldn't vape the same at the temp you set anymore, until you took it back off, let it cool down, then re attached while room temp.
I think it depends on who you ask. I've not had hands on with either the Snowwolf or IPV3 but I do have first hand experience with the SXmini m and DNA 200
I think in concept the devices that auto detect the resistance (DNA 200) do so in the name of accuracy but at the expense of consistency. Requiring the user to adjust their temp setting whenever the resistance is automatically changed.
I think the devices that lock the resistance (SXmini M) expect the user to know what the resistance is and to lock that, then any changes in resistance that may be imposed by environment changes are irrelevant and the device will provide the same power output as consistently as it was originally setup.
My experience is with the auto sensing, If I setup the device indoors then go from indoors to outdoors after a period of time it will auto sense a new much higher resistance (due to the outdoor temp change) and then when vaped will deliver higher voltage to maintain the Power setting I have set. In turn, burns the coil and dry hits. I assume but haven't tried that if I setup the auto sensing device outdoors or in a much warmer environment then went indoors or some place cooler I would get the opposite experience in an anemic vaping experience.
On the resistance locking device, in my experience once built and locked in it consistently delivers the same experience regardless of external temperature changes. I think locking the coil static resistance in the initial setup the device delivers the appropriate voltages based on that locked resistance and is not making changes to be more accurate but to stay consistent with how it was originally set up.

For the DNA40, atty lock was added as a way to defeat the problematic resistance "refinement" the board will do while sitting idle. Automatic refinement does give you a more accurate reading over time if you're always in the same environment, but it also gives you a variable vape when the external temperature changes, as Vlad just explained.
For non-DNA/DNA clone boards, it was there because there was no refinement in the first place. You have to tell it the baseline. Mods like this don't ask if it's a new coil.
Some boards do it without telling you, the "New Coil" process automatically locks the resistance, but they don't refine afterwords. To reset the baseline, you usually have to remove the atty, fire, get the check atomizer message, then replace the atty and select New Coil again.
And some boards have the ability to let you manually input your starting resistance (Smoke X Cube II, Koopor Mini).

I have three mods that 'auto detect' and two that the user needs to detect&lock manually (YiHi). Personally I think the YiHi method is more reliable but some 'auto detect' implementations appear to work better than others.
On my iStick TC40 simply screwing on a different tank and waiting a few seconds and the mod will read the resistance of the coil. The user COULD simply lock in this value but while the 'lock' is displayed on the screen, the next time the FIRE button is pressed the LAST LOCKED resistance will appear out of nowhere and be on the screen.
However the user NEEDS to get the "new coil y/n" message (after pressing fire) for any hope of getting their atomizer resistance correctly read and stored in the mod. Sadly if pressing "fire" actually fires the mod, the coil is now heated up. A frustrating process of attempting to get the "NCYN" message ensues. Once read and "locked in" the mod MAY adjust the resistance DOWN and make otherwise good vaping turn bad.
On the SMY TC50 the "NCYN" message happens during normal operation. Equally frustrating is that sometimes it will detect a tank and other times not so much.
The Apollo Reliant (SXK chip based) does somewhat better than the iStick TC40 and SMY TC50 however after some (unknown) idle time will again ask "NCYN" without the tank being changed at all.
Hence why I like the YiHi method. Hit two buttons, it reads the resistance and that value is locked in until you hit the two buttons again. Period. No auto anything here. I can vape on the same tank for days on end (removing and reattaching it at will) without any resistance value changes.
Automatic SEEM's like a good idea however I think more work needs to be done to make it more reliable and less intrusive.

Personally I like the automatic method better, at least on the DNA200, seems to work better than it did on the 40 for me.
I never particularly had a problem manually setting the resistance on my SXMM, it worked fine for me, but if a coil gets mangled or shorted and the end user doesn't notice, keeps firing away at their locked resistance, I could see that being a problem.
Either way, both methods work (on good boards), in the end it's just personal preference really.
