inconsistent resistance?

[meph1]

Hey guys!
AFAIK the minikin v2 does a real time check, but why is my resistance jumping so fast? if i release it it cools down to 52-53.
Are eleaf ec ceramic coils jump this fast from heat?
Its a .5 ohm coil.

heres a video:

A slight shift in resistance due to heating is perfectly normal.

.53Ω to .55Ω is a very slight shift, two one hundredths of an ohm.

so by jumping between .50 and .57 this linearily while being used is fine?

eLeaf EC Ceramic coils are made with SS (Stainless Steel) wire. SS wire does in fact increase resistance as it heats up in a linear fashion. Which is why it works in Temperature Control modes. So yes, that behavior is expected with those coils.

Thank you! I know some about electricity, and that the ceramic coil is made with ss316l, that is why i have a calm tone about this. afaik this is intended to happen to coils, but i didnt know that the range of nearly a tenth ohm is cool still thank you all guys, again

I wouldn't worry about a 1/2 ohm shift under fire for some builds....as long as shift is higher.. now if the ohm is fluctuating more than a 10th or so cold r from movement then I worry.

That level of change is completely normal, and I'm glad you got your answer, so that you feel less concerned about it. Welcome. Also, don't be alarmed down the line if different mods read coils slightly differently. There does seem to be some intra-mod variation. Again, it shouldn't be huge, but it may change then too.

I will add that if you were using a non-TC wire such as Kanthal and getting that much fluctuation then there would be a problem.

Half an ohm is way too much for anything... I meant like 5 maybe up to 10 100th of an ohm.
