Ohms Effect On Temperature?

[Herrick]

I've vaping at a temperature of 380F to 400F when the coil resistance is read at .17 or .16. But now for some reason, the same coil is being read as .15 and I need to increase the temperature to 450F to get that nice warm vape. Why is that?

Oh and these coils are supposed to be .15 but they're almost never shown to be at .15 on the screen. I'm using a Halo Reactor 80 with Halo coils.

It reads diffrent in. TC mode to power mode. dont know why but resistance changes slightly , hence why evolve dna boards can read slightly lower resistance in tc to power mode on most dna mods , reviewers say so too ,

What mod? Dna boards, and some others, do refinement, which means that they continuously read the resistance and adapt accordingly. The coil might not have been exactly at room temperature when first read, and thus the .16/.17 reading wasn't accurate, which in turn means that the temperature wasn't accurate. Your 380-400F was thus more akin to 450F, and with the more accurate .15 reading you need to adjust the temperature higher so that you'll actually get 450F.

I'm using a Halo Reactor Mega 80. I put in a new coil a couple days ago and it started at .17 then went to .16 and now it's been at .15 for a day.

Not sure if that board does refinement but it sounds like it does.

I'm not sure. It's really an Eleaf iPower 80 with the Halo brand on it.

I suspect buildup on coil and wick is causing you to crank up temp, not the resistance change.

Recently I got a stand alone ohm reader so I'd have a bench mark. My several mods don't exactly agree on the resistance. I've made the meter the arbitrator. Slight variations are annoying but not determining. What the mod is looking for is the reletive change in resistance, not absolute values.
