Mod not displaying same ohm rating as printed on the coil

I just changed out the coil on my TFV12 Prince tank to a premade coil that is supposed to have an ohm rating of .12 according the the packaging. My Aegis Legend is reading the coil at .14.....should I be concerned or just let it ride?

This is very common... more times than not the mod reading will not match the ohms of the coil. As long as it's only a few tenths difference it's nothing to worry about. Now, if it's a .5ohm coil reading .3, that might be a problem.

A lot premade replacement coil heads may be off by a ohm or two, not a issue.

Like the others said, you’re all good only being off a tad like that.
Be wary if you’re seeing a large difference though ( like pami said)

Enjoy your vape and kudos for being vigilant!
Safety first!

Yeah THAT normal.. I Would EXPECT To SEE A Variance OF 10 to 20 percent.. basically a .01 to. .05 ohm error can be due to a few once less or more tension when coil was wound. Or even a little bit longer legs on the coil. Or using a coil with the legs pointing same direction vs opposite. (1/2 wraps vs full)

I was wondering if there was an acceptable threshold and if I could figure it out mathematically.... Splitting the difference and going with a 15% threshold sounds good.

IF A COIL OR BUIL WORKS AND RESULTING OHM WONT CAUSES TO MUCH AMP DRAW I CONSIDER A COIL GOOD.... IF IT WONT PRODUCE DESIRED VAPOR... THEN IT GETS REPLACED.
