E2 Error and resistance

[Stonemull]

Loving my Provari .. but..

I'm using ego-T on mine, I have one 1.7 ohm and the other 1.9 ohm, both standard ones, not rated as LR anyway.

just checked atty with a good meter .. 1.943 ohms

I am getting an E2 error at 3.9V on the 1.9, fresh or partial discharged IMR 18650, .. so I'm forced to use a tank atty at 3.8V which is 2A and 7.6W, that sometimes throws an E2 in as well ..

I would really like to get to 10W, your FAQ indicates I should be able to get over 12W into 1.95ohm. Waiting for HV ego-T's could take a while..

I was under the impression that it was capable of 2.5A. Is there something about ego-T causing it to cut off earlier than it should.

I got an E2 on my Cisco 306 LR that the provari shows as 1.6 ohms. I was able to vape it at 4.0 for a little bit and then got the E2 again. I set it to 3.9 and haven't had an issue since. I'm hardly an expert as I only got it today, just thought I'd share my experience.

 

[Stonemull]

its strange .. the tank atty says its 2.0ohm and the max voltage I can use without the E2 reliably is 3.7 .. so 6.8W max .. sad
yet JTman's post above is getting 9.5W into an even lower resistance atty than mine.

put on one of my trusty ego B attys (and it tastes awful after the tank!) provari says its 2.4 ohm and it will drive it to the full 6V, 15W ! its totally disgusting of course and was just for testing purposes.

Can anyone else post results from their tank attys. I don't know whether to buy more on the chance of getting higher resistance ones or whether my atty is crook somehow. Maybe an intermittent short .. who knows. I don't want to thrash the thing, just would like to get maybe the magic 10W or so into the tank on occasions.

Wow, that is strange. I haven't run any LR attys on my ProVari, but I can run my 3.1ohm MAP Tank at 5.6v without getting an E2.

Just a thought..but maybe it has something to do with the tank atties cone shape..like it's running hotter with the cone or something..which could be triggering the E2 error?

Those are some very low resistance numbers for standard Ego-T atties! Brand new mine ranged from 2.2 to 2.4 ohms and I have a brand new, unused LR that reads 1.9 ohms all checked on a good dmm. For your standard t-atty to read 1.7ohms...that is out of spec by > 25% or so!

yup, I hardly used that atty as it was mainly a spare, the last time I measured it on a good meter, 1.497Ω (I stress, a GOOD meter) .. I used it for maybe one more tank from that point (on an ego 900 battery, did not put it near my Provari anymore), I went for another tank of juice, replaced it .. and nothing .. open circuit. I have since autopsied it though not got to the heater yet. I was amazed at the black liquid gunge build up on the coil under the spike plate, after only about 7 or 8 tanks of dekang juices.

I bought another tank atty yesterday, this one measures 2.2Ω and I'm happy at up to 4.2V on menthol. Dropped back to 3.7 now. Already tasting a little burnt. confident enough now to remove the spike plate, clean and replace though as required.

I hope the heater lasts longer though.

I was getting E2 error on a standard Joye Atty 2.2 ohm, Fluke meter tested. I rinsed it out real good with hot water and did a dry burn with it on an ego battery, then rinsed again and let dry. I no longer get the E2 error with that atty, I think it was building up gunk on the coils and causing this. Maybe this may help out others getting the error.

I'm curious Tasteles. Can you say what liquid you were using in this situation? I have a flavor that get's me the same result.

 

[Vermonster13]

Are you using an extension the get the T Atties on fully?

I was using a DIY RY4 flavoring from HealthCabin, 20% flavor and 20% VG at 6mg nic. It has a very slight tint to it. I'm still using the same atty and haven't had another error since.

Mine was DIY Butter Rum flavoring flavoring from LorAnn. No relationship there. I do believe though that flavoring buildup on a coil can change the current flow. Maybe some more so than others. This might be what was at the root of Stonemulls situation.

Stonemull: Those two original T attys, the 1.7 and 1.9 ohm attys...... were they reading that value new out of the box or had you been pulling juice through them previously with a batt other than the ProVari?

 

[Stonemull]

They where a few weeks old, I did check them when I first got them and I think they where both 2.2Ω.
They do seem to drop resistance for some reason or another, I find it hard to imagine juice could be that conductive but perhaps enough carbon or similar would do it.
Another alternative.. perhaps adjacent turns on the heater shorting together though that would be visible as a cold turn on the heater.

A coïncidence just happened. Right after reading this thread, my atty just died. I had just opened another thread to read and was mid vape and poof. Weird how it can be working great then just die, RIP. Hope this new one vapes as good as the last!

Please accept my deepest condolences Tasteles. I know you were very close.

Stonemull I have one that's gone UP in resistance over time. Explain that one.... I can't. I wonder if after dry burns some of the carbon fuses with the coil material?? Maybe they're using a different wire than what they've used in the past. I'm grasping at straws.
