Hi there, I will start by saying I had almost no knowledge on electrical matters before I started vaping. What little I do have I picked up reading the informative posts on this forum.
I picked up a cheap ($6) Cen-tech multimeter to test the resistence on my atomizers. However, I am having a problem with it. I seem to be getting consistently high readings off it . For example I just picked up 2 new cisco type LR 306 atties from COV,when I test them they are reading about 3.9 to 4.2 ohms. The same with some genuine joye 510s I just got, they are reading 4.7- 4.9. Just to be sure I am doing it right,this is my technique. The multi meter is set to 200,which is the lowest setting I have on ohms (sorry don't know how to type the little horseshoe sign). The black lead is plugged into the Com plug and the red lead is plugged into the VohmsMa plug. I am getting these high readings on all my atties.
The strange thing is that when I cross the two leads the meter reads 2.4 -2.6. Now if I subtract that from the readings that I got on the atties that puts them about at what they are supposed to be. The readins are also wildly inconsistent I just read them again and the LR cisco were reading 2.2- 2.3 and the joyes 2.9-3.0. while the crossed needles read .7- .8.
The multimeter works on a basic level; when I put it on a LR atty that I murdered it shows infinite resistence.
My question is this normal for a multimeter? It seems that if I just subtract whatever the crossed leads are reading from whatever reading I get from the atomizer at the same time, that would be what the resistence of the atomizer is. However, is this accurate, or do I just have a cheap, screwed up multimeter that is not working properly?
In any case does anyone have a recommendation for a better multimeter that will not break the bank.
Thanks for any help you can give this hopelessly non tech vaper.

Its relatively normal for very cheap multimeters, especially the analog ones with the needle gauge. Resistance is actually more difficult to measure accurately than voltage, and the cheap ones will typically give inflated values, or very inconsistent values. Best to drop about $40 for a good digital multimeter, like a Sperry, if you want more accurate ohm readings.
