Fixed my MVP. Quick question about ohm droppage

[JTyler82]

So, my O ring in my MVP 2.0 busted (around the connector pin). I pulled it apart, and took an O ring off a iClear 16 (like I saw online), put it back together, and everything is vaping fine, but I notice that my ohms are starting to go down or up now depending on how long I hold the button for

I didn't soder anything. I just pulled out the insulator, added a new O ring, put it back together, and now on my 1.8 coil it reads 1.7, and on my 2.5 protank head, it goes from 2.7 to 2.6, which it always read 2.6 for some reason on the stock head

Should I be worried about this? or am I okay? nothing is heating up, the battery is fine.

I Should also mention, on my 2.6 coil, I can go to 11 watts with no burnt taste, but before anything over 8.5 was burnt. Now maybe that's because my old O ring was broken, but idk. lol. Help???

when the wire (kanthal) gets hot it forms a layer aluminium oxide on the outside of the wire. over time this layer flakes off and you loose wire. the smaller the wire is in diameter, the more resistance it will have.
also the meter in the MVP, well pretty accurate is not top of the line. so there will be some error. i like to rewick my protank heads every other day or so. i use more absorbent silica and the vape is much better than a factory head. i started with a 1.8 ohm coil and used it for 2 months solid before it was totally trashed and the resistance was 2.5 ohms when i tossed it out.

"but I notice that my ohms are starting to go down or up now depending on how long I hold the button for"

heat will increase the resistance of any conductor because the atoms are spread out more at a higher temp when compared to a lower temp. this is normal.

So I didn't ruin anything by not soldering anything? I didn't take anything apart (no wires were disconnected), like I stated; i just put in a new O ring and put the insulator back a little tighter. But I didn't notice my OHMs dropping before I took it apart.

seems odd that the resistance would go DOWN well heating the coil. it should go up. but the ohm meter is not prefect. you would have to spend a decent chunk of change (several hundred USD) to get a digital meter that would be considered truly accurate.

Yeah. it went down by 1 point. but my PT2 is sitting at 2.6. but vaping is perfect. Even better than before. No burnt taste or any other problems. I Feel kind of accomplished that I fixed this myself. lol
