I'll probably get flamed for this but here it goes.
If you're using a regulated mod, an ohm tester is almost pointless.
If I took a 22g A1/34g n80 clapton with 10 3.5mm wraps and stuck it on an ohm tester, it would read about 0.02...not even close. If you read the coil before firing out the hotspots, you're just making pointless data imo. That coil should actually be around 0.2 or 0.3ish.
The mod has a built in meter. The real need for one is on a mech mod so you know whether or not you're about to be in a dangerous situation before and after you've fired out the hotspots. Also so you can calculate your amperage.
Any contact coil will jump a bit when you squeeze it. Especially n80 and especially if it's a prefired coil. n80 seem to conduct really well on the surface/on contact with the next wrap.
If you're using a mech, I'll slap myself for you.

yes it's not needed, but depending on which ohm reader you get can be handy... I find I've nearly hit the button a few times while working on mine, and I like charging a battery while I'm building.
if I use metal tweezers they will jump, they will also vary as it goes up in heat and cools when I'm burning it(coil master 521), less so with the ceramic ones.

The resistance should be stable. If it's not then tighten your leads and recheck all your connections.
Ohm Meter on a regulated mod really isn't all that accurate. I use USA Ohm Meter, now they have the reputation of being the most accurate and I have to agree.

Why does it need to be super accurate on a regulated mod as long as it fires the coil? What do you do with the data?
Actually it is worth mentioning that the wrap on clapton makes it hard to make good contact with the core.
The 510 screw is worth looking at too.
It's still important, I've seen mods go wonky and be off as much as a 1/2 ohm. The chip adjusts the voltage to its reading of the resistance.
Base the accuracy on recommendations and tests with high end Multimeters.

So if your DMM and mod aren't reporting the same load and you still haven't fired out the hotspots yet, what do you do differently?
I'm pretty sure the hohm wrecker has a different sort of ohm meter in it and the DNA chip is more consistent in this regard than my cheap mods but even though no 2 of my mods or my DMM reads the same load, what can I do?
I fire it regardless of what any of them say. There's nothing I can do to make them all the same but 80w on all of them is still pretty close...except on the 213. It's meter is off and if you do the A x V = W on the numbers on the screen, it doesn't add up. Even still 80w is about the same.
