I've been building coils for over a year, so I think I'm pretty good at it. The other day, I got my first dual coil atomizer,an Odin bottom feeder to run on my REO Grand mod. I sat down and wrapped a couple of 2 ohm coils out of 30 gauge Kanthal, and got everything all installed and, after fiddling a little, got it going at exactly 1.0 ohm. Super_X_Drifter has uploaded videos of his builds on this rba and mine are done the same way. Just for fun, I tore it down yesterday, thinking I'd give this sub-ohm craze a try to see if I could tell a difference. That's when the fun ended.
I spent hours yesterday fighting this thing. I rebuilt it using 28 gauge wire, two identical coils at about 1.3 ohms each, shooting for a little north of .6 ohms, Yes, I have genuine AW 18650, 1600 mAh batteries, I'm safe!! This is a 3 post atomizer, center post has the hole it in to run the wires through and tighten down. Anyway, I kept getting wild readings on my meter (I have the ubiquitous little black box meter with a 510 connection built in). My readings kept showing up as giant numbers, like 600-700 ohms, which I interpret to mean I have a short. But I don't have a short, I've rebuilt this thing over and over.
I finally noticed that even though the center screw is torqued down as far as I can get it, the wires want to wander around in the post, so I replaced the screw with a longer one. I'm still getting the wild readings. If I fiddle with the coils, the readings bounce around even when everything seems tight, but never drop into the range they should be reading. Pulling out one coil, I get a perfect reading on the other, it's adding that second coil that screws something up. There are no visible shorts, everything is neat and tidy, I know what to look for and there's nothing to see.
I've prodded around in the post to make sure there's no metal in them, I did get a tiny fleck of metal out, but they're clean now. I finally put in on my mod and it fired up, but very unevenly with hot legs. I didn't want to risk anything, so that was all I did. I'm getting the impression my meter isn't capable of sub-ohm readings, but it's the same thing 99% of you use. My digital multi-meter is pretty much worthless when I try it. I'm just assuming this meter will read below 1 ohm, it's capable of reading to 2 decimal points. Does work with my other toppers, batteries are fine in it. It reads 1 when nothing is attached.
Any and all wild guesses as to what I'm doing wrong are appreciated!
