resistance increase after use?

[themyst]

Trying to see if this is normal (I'm a newbie to the rta world).

I had a Orchid dual coil build at 1.25 ohms on my reader when it was fresh, but after a few days, it is now 1.5 ohms. I'm using this on a DNA30 clone mod, so it's regulated properly, but just wondering if this is normal. Still vapes great, no dry hits unless I go absolutely wild on the chain vaping, and even then its minimal burn.

Thanks guys!

First double check that your posts are still tight. However this is pretty normal during break-in -- Kanthal creates an oxide layer that insulates and prevents "shorts" between individual coil wraps. If you fire your coils several cycles before you wick, you can address this up front. Enjoy!

Yes, an increase in resistance over time is normal.

I find if you tidy your coils with tweasers you get less resistance change.

I find that I get a 1ohm change sometimes. I've been tacking it up to a coil that's resting near the higher ohm that it's jumped up to. I've never had a coil jump that high though, could be the connections aren't tight enough.

You definitely should not be seeing changes anywhere near that large. A loose connection is likely.

I'm saying it's probably a point of an ohm that's changing. So let's say my coil is actually 1.28 ohms, it's reading at 1.3 ohms on my regulated device after I start vaping on it.

That's perfectly normal. You said you were seeing a 1 ohm change, which would be drastic!

Double check it on your meter. Your mod might not have an accurate ohm reader.

Sorry, I meant tenths of an ohm change.
