Ohm Reader problems - different to no readings

[Zaheer]

Hey guys I didn't know where to ask this question so I thought I'd ask here. My ohm reader has been acting up, when I'd turn it on and screw on the atty (Plume Veil 1.5) it'll read my dual parallel 6 wrap 24g build as 0.00. I ended up changing the batteries and it now reads 0.11 when I turn it on after screwing it in. I would then take it out and screw it back on and it'll read 0, but turn it off then on and it'll read 0.11 again. I borrowed a friend's ohm reader and it would read my build as 0.13. Screw it off and on and then reads 0.15, turn it off then on and it's back to 0.13.

So I don't know if it's something with my ohm reader that's not reading it correctly or if it' actually 0.11. I am using an IMREN 18650 38a 2600maH battery. I should also note that the plume veil's silver plating on the contact is starting to chip away but it's been fine when I had a 0.22 build on it.

Should I replace my ohm reader? Maybe it was a short or something but I don't know what would cause my ohm reader to short. Unless it was this marble I found that could questionably be metal that I put on the post of the ohm reader to take a quick picture and accidentally left it on there before leaving for work. I don't know but with the battery I'm running I don't want to be pushing the crap out of it/have a potential to short. Thanks guys.

Any time that you're dealing with a coil below 0.2 ohms, you've got the potential for a short. That's to say, it's possible that the button or any particular part of your mod might have more resistance than the coil, and the heat would generate excessively in that point instead of where you want it: The coil.

That said: ohm readers are fairly sensitive devices....but they're not perfect. It will have some variance, and your coil can have a little variance as well when under load. And keep in mind that a coil's resistance will change slightly as it's used and gunks up.

Keep in mind that whenever you go below 0.2 ohms, you're dealing with a potential short anyhow, that's generally considered the 'safer' spot when you think about errors in the readings from the coil and the battery, and everything else.

Your build is simply too low. At lower than .2 you basically short your atty, and there are no batteries that can handle that load. Ohm meters are not accurate that low and that's what you're experiencing.

You'd need a good meter not one of those screw on testers to work good at that low a level. As a doctor once told me about my hearing and shooting hobby with out hearing protection " your climbing fools mountain if you keep doing that". At that level you're going to eventually vent a battery OR WORSE because the tolerance of the meter will bit you. Keep it above .5 ohms if you can so you won't be tempting the fate or Ohms law and exceed the limits of a mod or battery. Or invest in a really good VOM like a Fluke and they are expensive. I never ever go below .2 and only on mechs with quad or higher builds. The best build I have right now is in a TOBH 28 ga 7-8 turns quad .4 ohms vertical coils. On thing if your a cloud chaser. Go higher resistance but higher wattage like with a VW like a SX 330 or SX350 mod.
