Ohm reader and box mods

[Fajar]

I'm still a long way from using and building RBAs, but i guess it wouldn't hurt asking from now.
I've seen that regulated box mods can read the ohm resistance of coils, so would i still need an ohm reader for building coils? Some people say that ohm readers are more accurate than the box mods?

Man do i love this forum! Alot more helpful and responsive than the local forum in my country,,
I don't think I'll have any intentions on learning to build those super sub ohm coils, to much hassle IMO,, As for mods, I'm eyeing on the evic mini+toptank mini for my start on RTAs, the dna200 is way off my budget XD
Really amped to learn more about RTA's, though it's gonna be awhile before actually trying one out, seeing as I've only started vaping last week,, Lol
Thanks a bunch for the tips and info guys!

I'm in almost the same boat. I've only used Ego's so far but I've been looking to upgrade and decided on a Toptank mini as well, just like TS.

I do already own a decent multimeter but I figured one with a 510 thread would be much easier to use, plus you have something to build on as well.

There's plenty of cheap (5 US$ or so) boxes for sale but I went looking for something a bit more stylish and came across this one:

You can find them on ebay & Gearbest for less then ten bucks including shipping (look for "Tomtop atomizer checker"), they come in different colors and it is USB rechargeable so doesn't require extra batteries.

Some specs:

Material: Aluminum Alloy
Resistance Range: 0~20(ohm)
Voltage Range: 0~12V
Accuracy: 0.01V / 0.01 ohm
Battery: 3.7V 270mA
Input Voltage: USB DC 5V
Estimated Standby Time: 30 Hours
Charging Time: 30 Minutes
Item Size: 45 * 25mm / 1.77 * 0.98in (Dia. * H)
Item Weight: 41g / 1.47oz
Package Size: 7.5 * 5.5 * 3cm / 2.95 * 2.16 * 1.18in (L * W * H)
Package Weight: 63g / 2.22oz

I can't find any reviews on it except on Gearbest so it might suck, but even then I figured I just have a nice atty stand, lol. I'll compare values with my trusty multimeter when it gets here & do a little review on it if people are interested.

since you're not into building coils and mechanical mods, yeah, you can rely on your mod's ohm reading.

the latest meters from geek vape and coil master even have a battery checker as well as a firing tester

Hi and welcome. I recommend a stand alone meter, myself. I like them because you'll find, as you acquire more mods, they are not calibrated to read the same. I also think it's useful to do all your building on one meter as this helps you attain consistency. A stand alone also helps you mentally "calibrate" your mods' meters so you can get the same vape across different platforms. Finally, the meter itself serves as a handy building stand and is, IMO, safer than building on the mod. Mods are taller than meters, thus easier to knock over. You can also get an accidental fire when building on the mod by, for example, knocking it over and accidentally hitting the fire button trying to grab it. Most meters don't have enough power to fire the coil. (Some do, they're built to test fire coils in addition to measure them, but the price on those if higher.)

If you want to look at one, you'll fine USAOhmmeters offers their "Ultimate" model at about twice the price of a cheap one from eBay, and is a much better piece of gear. Just my

As for myself I've always used a good seoeratate ohm meter for all my builds..it also makes a great platform for actual building and tweaking getting my perfect target resistance.. It also saves wear and tear on the 510 threads in my regulated mods, and lastly the display (readout) is easier to see and without using the batts in my mods.. Been doing it this way for years, works great for me.

No idea about that piece of gear, but as you say, it'll make a nice build stand no matter what. I have found most DMMs-- I have a Fluke 87 and a 287-- are not reliable in the subohm range. This is lower than they are designed to read. I lust after a good 4-wire Kelvin probe milliohmmeter, but these are a Franklin and up.

This is what I've been using..about $28 from my local B&M..

So are the Flukes,,laughing. I do use an old BK precision VOM analog for Mech builds..

Yeah, frankly I doubt if it will be very accurate, especially in the sub-Ohm range. I just hope it'll be consistent enough even if it is a bit off so I have some idea where I'm at after cross-referencing it with my multimeter until I get to know it. We'll see. But if not it'll be a nice atty stand and build thingie that will match the style of the Evic VT I plan on getting

Lol, so they are. But then, they're also a lot more versatile than a milliohm meter. I used to do that work; I needed good gear.

 

[daviedog]

I need 16 to 30 millamps to adjust the idle current on VT plates. Lost in the backwash of my DMMs.
Oh,, to OP using your Regulated mod to measure resistance is fine..

 

[93gc40]

Yes, you need a stand alone Volt and Ohm meter. PERIOD. Sure the mods meter can read the coil..... BUT, it cannot tell you if the problems you might be having are Mod, battery or coil/atty caused. Yes, the ohm meter in the mod is probably a better OHM meter than the average VOM meter you get at the hardware store, so a dedicated atomizer Type ohm meter is a must. If you don't have the scratch for a high end VOM. Besides a 510 ohm meter makes for a great building stand for the atty.

 

[daviedog]

A mod will only work according to it's own internal resistance readings. If you're pinched for $$$, not the greatest investment.
Low builds on a Mech? Buy the best meter you can..

 

[Scy123]

I haven't used an ohm reader since I got a regulated mod. Probably not the safest practice, but I don't see much of a danger.

Can't say anything about accuracy.

 

[Fajar]

In that case, as long as the coils are still a safe range from the mod's resistance limit, then an ohm reader wouldn't be needed?

 

[Scy123]

Yea most mods have ohms limits that will stop it from firing. I only say most cause I hear the dna200 will fire it regardless of limits.

As long as it does not fire anything not within limits it should be fine.

 

[sonicbomb]

Stand alone reader can be more accurate if you spend decent money on it. However a cheap one may well be less accurate than the meter in your mod. A high quality resistance meter stand alone is only really a necessity (in my opinion), if you are building for a mechanical device, especially if it's a super low resistance build. Below 0.2 ohms, even a tiny increment can make an enormous difference in the amperage being drawn from your battery.
Most regulated devices have lots of safety features built into them to protect you.

 

[Nuchuga]

It comes down to preference. For new builders and even an experienced builder like myself, I would recommend an ohm reader for safety. While newer mods have amazing protection and spot accurate reading, there are other things that the mod wont take in account for. Best bet is to just use an external reader

 

[DebiK]

I always build on an ohm meter.
