so i made a coil for my rba and ohmed it out to 1.5 with my meter. put it on my svd and it says 1ohm so it wont fire. is there a special way to check my ohms? got 1.5 on connector and from + post to deck. am i missing something?
question on checking ohms

umm, not much to go on. what kind of rba is it? what gauge wire? how many wraps?
assuming your meter and svd are both reasonably accurate, my first thought is you probably have a short somewhere. possibly coils touching each other or a post? if you're using a gennie with a mesh wick, possibly not everything is fully oxidized?

If your multimeter isn't auto ranging, you gotta subtract the meter's internal resistance.
First you touch the leads together, and get a reading. For example, mine says 0.5Ω when touching the lead together. Then after you take a measurement of your atomizer, (another example 1.5Ω), subtract the meter's internal resistance of 0.5Ω, and you get 1Ω for your atty's resistance.

Make sure both your tester and your SVD have fully charged batteries. I find my meter gets less accurate, especially at less than 10ohms resistance, when the battery starts getting low.
fist coil was a five wrap of ribbon. my second is an 8 wrap of 30 gauge. meter says 3.8 and svd says 2.9 on second coil. no idea about batteries in meter but svd says 3.8v. my meter might need batteries, been five years or so. rba is a cobra clone i just got.

hmm... sounds like the meter might be a little high then - probably just time to change the batteries as was mentioned above. granted, there are a lot of other factors that can affect the resistance (ie, tightness of coils, size of wick, etc.), but for the types of wire and number of wraps you used, i'd expect the resistance to be closer to what your svd is saying.
+1 on this. Multi-Meter How to for Electronic Cigarette users - YouTubeYour SVD may also be measuring resistance "under load", which means it makes its measurement while firing the atty. This is generally a more accurate measurement.
Since you sound like you are relatively new to an RBA, perhaps look over this guide I wrote for beginner users of RBAs: http://www.e-cigarette-forum.com/fo...-tips-vapors-looking-try-their-first-rba.html

I was lucky to score one of those little black boxs to check resistance by just screwing on you atty onto it. Works pretty good, but when going sub ohm I always double check resistance with my Fluke 87 true RMS multimeter.
it was the batteries. also i had some shorts on my mesh to work out. my meter is a fluke style blue point
