svd is burning up cartos and atomizers

[kev2kta]

Been vaping 2 months and everything was good till a couple days ago. I've been enjoying my itaste svd the last couple weeks using vaping zones ego mega dual coil LR cartos and their desert ship eliquid. My first couple mega cartos worked great, but now no matter what I connect it tastes nasty and burnt. I even tried some brand new smaller 510 cartos I had left over from my smaller ecigs, both were burnt tasting right away. Tried my protank i had put away due to nasty taste and leakage a while back, tried the last new atomizer I had, same nasty taste.

So today I got another order from vapingzone with a new 5 pack of the mega cartos, filled the carto and let it sit for a bit, still tasted burnt right away. Now im afraid to attach any of these other new ones at $3 a piece. I have wasted a lot of cartos and juice on this. My voltage is 3.8, wattage 5.5. The svd reads the correct resistance and shows no obvious issues except their isn't much vapor being produced. Even at 3 volts it tastes burnt. I wonder if fasttech will do an exchange, they just emailed me a followup asking how I liked my product.

You might as well see if fasttech will help. But I do have a couple questions for you. Are you using "mean" or "RMS" mode?? Also what is the ohm of your coils? Is your SVD actually showing (at least relatively close to) the resistance of your coil?

 

[kev2kta]

I use voltage mode if that's what you are asking. The cartos are rated at 1.5 ohm and the svd reads the same. Im filling out a ticket now with fasttech, hope this doesn't take a month to exchange.

 

[jefsview]

are you running it under watts or voltage?

Did you try lowering your voltage with a fresh carto and work your way up?

No. The SVD can measure voltage in RMS or AVG mode. What do you have it set to? It should be RMS.

No. The SVD can measure voltage in RMS or AVG mode. What do you have it set to? It should be RMS.

Perhaps I overlooked it but I don't see anything in the Innokin SVD manual about either RMS or AVG mode.

I was just looking for instructions on how to change it to RMS mode but couldn't find it :/ Maybe search your users' manual for RMS/Mean mode?

The reason I am asking this is because RMS is a lot more accurate. I got a Zmax recently and it come out of the box in Mean mode. I was burning liquids at like 4.0V and up. Once I switched to RMS mode everything was fixed! RMS stands for something like "Root of the Mean Squared" which is a special logarithm that makes your device way more accurate. Now I can vape at 5.5-6 volts and it only burns the delicate juices. So, long story short, if you are on Mean mode then your device is firing HIGHER then what your setting is. So change that to RMS yo!

Yeah I know I have seen it though! And have seen other posts about it being able to use RMS but can't find the instructions to switch it! The interwebs has failed me

 

[BigLebowski]

I believe the SVD doesn't have the RMA/Mean mode option like the Vamo.

 

[retired1]

Disregard. Looked on Innokin's website and the SVD does not have the ability to switch between AVG and RMS. It's RMS only.

Sorry about that.

 

[BeatboxHero]

So you are already on RMS mode. Sorry! Wild goose chase

BUT!! I think I might have figured out your problem! Lets do some math

At 3.8 volts with a 1.5 Ohm coil you are pushing out 9.6 watts and 2.5 Amps! That isn't dangerously high but I could see how things are burning. With a single "low" resistance coil, if I go above 9 watts it can burn depending on the juice. And as I understand it, what it really comes down to is Amps! 2.5 Amps is "relatively high". Like I said, nothing dangerous, but still kind of high.

SO! I recommend switching to VW mode and trying out around 5-6 watts. That should lower your output. I guess it wouldn't go much lower then 3 volts but maybe it will help. 5 watts is still around 1.8 amps. Do you have a higher ohm coil? Just to test some stuff with?

 

[BigLebowski]

It's best to start low and ramp up the voltage/wattage until you get that slight burnt taste and then move back to previous setting.

Thanks for the replies. I went through my manual and searched before coming back and seeing there is no switching modes. What I don't get is that the first couple mega cartos were great for a week. Just tried 2 smaller cartos with 2.0 ohm rating, tried at 3.0-3.7 volts and horrible taste. These were brand new last night. Something isn't right. Maybe its the bottom half of my eliquid , maybe I didn't shake it enough before using? I use the 50ml desert ship from vapingzone, maybe ill try the new bottle I got today with another carto. Now grasping at straws and trying to minimize analog usage. Hopefully fasttech will exchange it, but it will be a long wait. I was just about to get another svd next week for backup.

Switch your device to watts. Start at 5 watts and work your way up. Your voltage is to high, pulling over 9 Watts at your current settings. Depending on juice, they can start to burn at 7 Watts and 8 Watts is pushing it. Reduce voltage or watts and start over from the bottom. Not an SVD problem from the sound of it.

Good thinking! Like billbeckusa said, It's most likely not the SVD. Juice is a good place to start looking. Do you have a meter? If you can get your hands on one you can verify it is putting out what it says it is. Grasping at straws a little as well

Well I filled another new mega carto with 3ml of the brand new desert ship eliquid i received today, same burnt taste. The carto reads 1.4 ohms on the svd, wattage at 5w, voltage at 3v. I dug out my voltmeter and with the svd at 3 volts meter reads 1.4v, at 3.1 volts it reads 1.5v,at 3.2 volts it reads 1.6v and so on. In power mode at 5w, I get 6v, at 3w its 5v. Not sure what to think of these results. This testing was done touching red lead to center brass piece on top while touching black lead to ego threads and pushing button.

 

[BeatboxHero]

Well I have never used a voltmeter that way. But, assuming you are doing it right, it seems very inconsistent. And after changing everything else on the device I wonder if that is what is leading to the burnt taste?

 

[kev2kta]

Fasttech is going to exchange it. I will also purchase another one for backup since they are cheap. After I get the new one I will follow up on this thread with results.

In regards to the SVD and RMS...
"For what it's worth, I've been informed that the SVD does use PWM calibrated by RMS so it should offer the same vape experience as any other properly-calibrated PWM device."

I agree with Bill. Switch to wattage, start very low and slowly work your way up.

This is why backups are so important. Something IS WRONG here, for sure. Maybe it is your SVD. I have one and never get readings like this. In fact, I have a dozen or more regulated mods and don't get readings like this. I have yet to hear of a defective SVD and the chip it uses is pretty reliable, if somewhat inaccurate (somewhat, and not a big deal). Hhhhmmmmmm.....yeah, send it back, but do get a backup. Multimeters are notoriously difficult to use, until you get to the more expensive units. Best to you.
