OHM numbers aren't matching up?

[C0BRAKAI]

I have kangertech 1.8ohm coils in my mini pro tank 2 hooked up to my mvp v2.0 but when I check the ohms on the coil it reads 2.1 ohms on the mvp, can someone please explain that to me?

When it comes to the stock coils, you're going to find that they all aren't spot on. Some are going to read higher, some may even read lower. Nature of the beast.

Yes it's entirely possible that the coil is 2.1 they are known to be off occasionally.

Do you mean you measured it at 1.8, or it's got 1.8 written on it? There are always tolerances in manufacturing.

0.3 ohms is on the 'they missed' side, but you can't expect them to 'hit' always for the price we're paying.

also keep in mind that a hot or cold coil can give different readings as well

Check it with a dmm if you've got one, PV could be off/wrong. Other than that, as others said, they generally don't hit the mark every time.

Someone on ECF put up some test results a few months back showing that oHms meters can be off by up to +/- .4 oHms. No idea whether this is true of MVP btw.

Yeah, I've tested Kanger heads that were off a bit. Usually on the higher side. I've been making them lately and when tested on my meter they usually hit the same mark on the MVP. It's nothing to worry about that I'm aware of.

Still vapes and tastes good? That's a win.

It is really tough to train 7-12 year olds to be completely consistent for the full 16 hours of their work shift in the Chinese factories

3/18 = 1/6 = 17%

17% error.

Does the mvp read 0 ohms correctly?

Thank you for everyone's input, I am still trying to wrap my head around all the terminology and find out what works and what doesn't. There is still a learning curve to try and get ahead of but with technology lately it is hard.

There is a learning curve for sure, but sounds like your getting the hang of it.

Are there any terms in particular that you'd like to get a definition for in this thread?

Welcome to the forum btw.

I got a Sigelei ohmmeter in the post today and my "1.8" Kangers are measuring 2 - 2.3.

There is clearly a a QC issue at Kanger or Sigelei (or both).

 

[C0BRAKAI]

Is there a definition list in the beginners forum? If not we should get a sticky of that, and is there a definition list of building a vape? I haven't really seen a lot of broken down into simpler terms for that, however back on topic.
What coils are more true to what they are supposed to be? I do not have an ohm meter and I don't know enough yet to start building my own stuff.

I like this list: Ecig Terms and Definitions, Vapeology

As far as accurate resistance coils, none will be spot on. 0.3 ohms seems like a lot, but both the coil and the MVP have a tolerance on them. So if the MVP is reading high by 0.15 ohms and the coil is actually only 0.15 ohms high, that would give you the result you see.

OTOH, it really doesn't matter because you have a variable voltage device. The high resistance means the coil at 4 volts will be a little cooler than it should. All you have to do is turn up the voltage a bit to compensate. It's not perfect, but it is what it is
