Ohm checker has broke!!!

[Zutankhamun]

right. I'm comfortable now, so unless I'm in bed (with the fear of just falling asleep with my device),
I use mechs pretty much all the time now. I'm not a fantastic builder but I just do standard
Kanthal coils, at bout 1.2. I'm good enough and they're fine for me.

My eleaf ohm checker is constantly giving me ridiculous readings even when equipment and rta is cleaned.
I don't have any provape gear and so my regulated readings are all different as well.
With all readings I get +ohm and the coil looks like normal and tastes the same in my mech.

Do you still use your bits like that or do I have to invest yet another £5 in another reader?
My bank account would prefer it if I held on to that 5ver.

I thought you had a regulated device or two hanging around from before? get an average, account for a buffer until you can afford that extra 5ver.

Yeah that's what I mean. My sig 150 gives me 1.08 and my Pegasus gives me 1.18. I've got loads but they're all different.
That's cool though right? Close enough... hopefully

 

[Cheallaigh]

just average and buffer... always buffer with a mech to be on the safe side... don't want to end up like tutankhaten!

At 1.18 ohms you're drawing around 3.56 amps. At 1.08 it's 3.89A.

Unless you're using really low output batteries ... you're fine

ETA: BTW, I got those amp numbers from the Steam Engine Ohms law calculator. Enter 4.2V and the resistance you want to use and you get amp draw.

I'd gladly spend a 5'ver (although over here it's a bit more) for piece of mind. A new face is gonna be much more.

Thank you. Yeah I use them a lot so I'm fine with that, just don't like the fact that my readings are different.

Woke up to use toilet, checked my emails (as always, haha),
saw ur message and went to eleaf.
£9.99!!! Or eBay £7.99!!!
Yeah I know, my face and all that jazz

I'm not sure a cheap ohm meter will be any more reliable than a good regulated mod. My experience is that the variation seems to come from how good the connection is. Cleaning, screwing the tank down harder onto the mod , even taking it off and putting it back on, can all change the reading slightly.

A good multimeter testing across the screws might give you an accurate reading of the coil itself. But you really want the resistance of the whole unit including the tank parts. Not sure it's worth fretting about. Like someone said, just accept that it's an approximation and don't go too close to the limits. Only place you need to worry is if you are going for really low ohms on a mech.

I just spent a little more and got a Coilmaster 521 reader. Glad I got that. It seems to give more consistent readings.

 

[Alien Traveler]

Never had a specialized ohm meter. Regulated devices are good enough for me. And I build coils of 1+ ohms as you do.

 

[VHRB2014]

I just realized? LOL

I have`nt used mine in some time. LOL, Ohh no.

(Kennedy so easy..........)

 

[bwh79]

If I were in the market for a new ohm meter, I'd probably check out USA Ohm Meters (usaohmmeters.com), but I don't know if they ship internationally.

 

[Cheallaigh]

happy with my 521.

 

[Zutankhamun]

Alright thanks guys. I'm careful anyway but...
(Hope no newbs are on the prowl)
Just got caught up in the safety hype for a mo.
Now I've got a broken dmm and an iffy ohm reader!!!

But like you've said I use my regs to check anyway but I'll get some new gear soon.
And like ppl have said, it's 1.2 so a little bit either way is ok.
Just a no-no for those sub zero conditions.

Edit: sub zero? I meant sub ohm.
I'm watching a doc about the arctic. You all know what I meant.

Although. Negative building is the future I hear

Thanks again

I'd bet that a modern regulated device reads the resistance far more accurately than a cheap ohm meter (and possibly better than a 521 as well). I'd also trust a mod over a multimeter. Multimeters simply aren't designed to read such low resistances.

I would have to disagree with you there my good man.

Originally using steam coil building app to get a 1.2 I was told with
1.7mm screwdriver and 28 guage kanthal I would use 7 and a half wraps to get said res. With the eleaf ohm checker always basically 1.2, maybe a point plus or shy.
Every box gives me a (big) different reading they are all sigeleis and other well known brands. The ohm readers fine.

If your going super low then like you, I would question it and need a pretty high end guarantee. Fluke springs to mind

 

[tokarev]

If you go with a multimeter, be sure you get one that is designed to measure low resistances. Most of them (even Fluke) are not accurate at the ranges we measure for coils. I remember reading somewhere that the Fluke 187 could do it but I don't know about any of the other models.

 

[daviedog]

A DMM reads voltage, continuity, in addition to resistance.
Some ohm checkers @ 15 to 20$ is just bad economy.
I build vacuum tube guitar amps & have several VOMs & a BK precision bench meter.
Do i use them to build coils? Nope..

On the got caught up in safety hype comment @Zutankhamun this is a saying I try to live my life by..........

You can never be too safe!
