new to rebuilding coils and in need of help

[metathirteen]

i just signed up to the forum so i wanted to start off by saying hi
i've been using EGO batteries for about 2 years now and i love them and recently came across somebody selling kangertech T3s clearomizers so i tried them out and LOVE them. im waiting a little while longer to upgrade on the battery and getting newer more advanced models since i love this one so much and i still feel its time hasn't passed just quite yet. i found a video online on how to rebuild T3s atomizer coils and lost my mind, i can just rebuild the coils now. this is no longer just an alternative to smoking cigs, after finding out i can just rebuild the coil it is now become one of my new hobbies. i purchased a multi meter (never really used one before) and i bought 33 gauge wire with 1mm silica wick, i read 32 gauge is preferred for beginners and this was the next closest size i could find available. so today, i made a coil to get my hands dirty. it WORKS!! im so excited, but the thing is im having a problem testing it. the lowest setting on my multimeter is 10x for ohms. everywhere i see everyone has a digital one and they set it to 200... it reads out at about .5 ohms but i tried testing the coil ive been using (2.2ohm purchased, not a rebuild ) and it reads the same, and so does the older tornado tank atomizer i have (slightly lower, maybe .3-4).

so what i want to ask is, is the multimeter i have a dud or am i just reading it wrong? and what r the chances of me blowing up my battery by doing this?

i have a kangertech T3s clearomizer, 2.2ohm atomizer in it (not the rebuilt one), a joyetech EGO-C upgrade passthrough 900mah battery, and a cheap $10 analog multimeter from walmart. the battery i have confuses me because the box said joyetech but on the side it says vaporecig which is where i bought it from, and i ordered the 900mah but it looks like an 1100mah.

Welcome to the forum. I have been vaping for 2 years also and I am just now thinking about learning to rebuild some of my coils. So, I have been doing a lot of reading on the forum and from what I have read they say it is best to get one of those $20 ohm readers that many of the vendors sell. They are very accurate and very easy to use. Next choice would be a digital multimeter. I can't remember exactly what some have said about analog multimeters but I got the impression that it is harder to get accurate readings on them and we need to be as accurate as possible when we are building coils so we don't damage our batteries or equipment. I am going to wait till I have the funds to get one of those ohm meters before I start trying it. You should type in rebuilding coils in the search and read through the posts or type in meters and see if you can find something that helps. I have been using the aspire bdc clearomizers and the aspire nautilus tank so, like you, I was excited when I found some good videos showing how to rebuild those instead of paying $2-3 per head.

As for the battery you got, did the place you got it from say it was a genuine joyetech? I know that some vendors buy batteries and have their names put on them but I don't think that joyetech would let them do that. I may be wrong and maybe someone who knows for sure will answer. Hopefully someone who rebuilds coils will know more about the type of meter to use. Sorry if I didn't help much but I wanted to say welcome.

If you can post a picture of the front of your meter, it will easier to figure out your problem, there's literally hundreds of different styles and types ....

An ego supports roughly 12watts (figured 2.5amps@4.8 volts). If you had a .5ohm build on that battery it would be pulling 46.08watts. That being said, the ego is a protected battery and should detect a "short" and not fire, if it did fire it would go boom. This means i'm 99% sure your battery wont blow up because the meter isnt displaying accurately. The 10x setting means just that, multiply whatever it shows by 10, but if multiple different known resistance coils show the same readout its bad meter or user error. One way to check it would be to hit radio shack and buy a 10ohm resistor for a nickel and hook it up to your meter. To make life easier on you all together, take back your walmart meter for refund and get an ohm meter meant for ecigs like Portable Ohm Meter - Avid Vaper. You can find them around 10 bucks sometimes.

One of the best areas ive fount to get info on building coils is RipTripper on you tube. Some things that are a must building is a chart that tells you resistance per inch of different gauge kanthal, and a ohm meter for your rba, google vapor ohm meter and bunches will pop up. Most important would be an ohm calculator to help determine your amps being created, this is important to keep your boards safe if your using a regulated mod, and you safe if youre using a mech.

I ordered the 32 gauge wire, but then I found this : $3.25 Pre-made Welded Wires - NR-R-NR (100-Pack) 100-pack - 0.18mm (33 AWG) / 2.2ohm at FastTech - Worldwide Free Shipping

Check the resistance of your multimeter by holding the leads together and waiting for 10-20 seconds for the reading to settle. Then subtract this number from the reading off your atomizer. My multimeter has a 0.1 ohm resistance and usually takes about 10 seconds to settle down and give a precise reading. To check the resistance on an atomizer, I screw it into its base and screw the base into the tank. Then I place the tank upside down on a table (exposing the atomizer). Then place one lead from the meter into the air hole in the bottom of the atomizer and the other lead against the threads, making sure to keep still. I get an accurate reading this way as confirmed with the resistance checker on my Vamo.

Also, if I may suggest, pickup some 30 ga wire ($8 for 100' on Amazon) and some organic cotton. After making the switch to cotton and micro coils, I have no interest in using silica again.

I don't understand "10X". No clue. What make/model meter is it?

Any cheap meter will have a lowest, and a highest setting for resistance. Check the one farthest one way, then the one opposite it, farthest the other way, and compare the readings on a few attys whose resistance you know from their markings to the meter's results. (Keep in mind, these resistances can still vary a bit due to manufacturing tolerances). One of these settings has to give you desired results, or else you bought a total POS meter.

The $20 Ohm meters from vape shops are ok if all you want to do is check resistance.

Take my advice, (even if you just go to Radio Shack) and get a decent Multimeter. $30-50 is plenty for your purposes. Something with auto range functionality. Resistance(Ohms), DCVolts, and a continuity checking are all great features to have. Continuity is nice for pre-checking pin connections on mech mods. Plus, sooner or later you're going to want to test IMR battery voltages too, thus the Multimeter is money well spent.

The ego battery has PCB protection, and won't fire if the atty is under a certain resistance (1 Ohm for most batts). You should be careful, but it's not like you're using a mechanical mod and could vent Li-Ion batteries from shorts.

Best bet and easy is get a 2-in-1 Ohm & Voltage Meter

Then place coil on the base and test. It works great and I don't use my meter anymore.

Look into micro coils with 30 guage. They perform great and that what I run in everything.

thanks for all the replies!!

i figured out what i was doing wrong, i didn't adjust the zero dial to adjust the meter. it started reading accurately but i ended up just returning it and putting down a couple extra bucks for the digital one. its reading 2.0ohms, and my untouched coil reads 2.5ohm. as for the battery, im not sure if its a genuine joyetech, the box it came in had the logo and everything on it, the only difference was the battery itself had the company logo from where i ordered it.

joyetech does allow rebranding of its products. for example totally wicked calls the eGo a "tornado". Joyetech brand offline electronic cigarette shops
