IPV2S unstable resistance problem - something to do with spring loaded connector?

[Papa Lazarou]

I have had a problem with the resistance jumping about on my two week old IPV2S. It started maybe two days ago. Resistance was jumping about wildly causing burnt hits, one melted coil etc. I've already contacted the vendor who advised me to send it back for them to check it over. However in the meantime I continued using it a little and was trying to get a video of the problem I could use in the event of a dispute...

Anyway, as luck would have it, it seems to have corrected itself, at least for the last couple of hours. Resistance now appears to be reading stable and it's working fine. The only thing I noticed that was different is prior to the problem "fixing" itself, there was a slight creaking noise coming from the spring loaded connector as I tightened down an atty. This noise now seems to have gone and it's reading the resistance fine. I am therefore wondering if these two things are connected.

MY main question is, has anyone had a problem like this on the IPV2S, and if so is there a reliable way you've found to fix it? Also has anyone opened one up to have a look at how the connector is joined up? Are wires soldered directly to the centre pin (I'm wondering if it's a bad solder joint here) or is there some more elaborate way it's connected up? I am wary of opening it up myself, at least while it's so new.

Help or advice appreciated.

Thanks

I had the same problem yesterday, then I decided to open up my rda and tighten the screws on the post down and that solved my issues with ohms fluxuating

I had the same problem when I first got mine.I even went as far as contacting vendor for an RMA. After checking more into the problem, I found it was indeed my orchid's problem. fixed that and then felt like an idiot . I just assumed it was the IPV2. Lesson learned!

What was the problem with the orchid if you don't mind sharing.

I had the same as Lundude. It was the 510 pin on the Orchid v4 not making a true connection. tightened the pin and it's good as new. I think most problems are with either the 510 pins on attys or the screws on rda posts coming a little loose and not securely holding the wire down snug.

The adjustable 510 screw on the orchid for me. it gets a bit wobbly if not tightened snug.

Good to know :] Thank you

I also ran into that problem and you're right, adjusting the contact screw on the atty fixed it. Haven't had any fluctuations or problems since.

This is the biggest downside of VW (as opposed to VV)
Something gets loose and you get a nasty surprise as a result.

I had the same problem in the past using Sofia and Dripper by leo and it was because of the bad connection between non resistance and resistance wire. Now with the welding device resistance is stable as a rock ! (wow, my first post here outside the new member section).

Mine reads .2 high and i really have to tight my atty down to get it to have stable readings. I have the older version with the adjustable screw 510. Anyone else experiencing something like this?

 

[rustafar]

Mine is the upgraded version, It has the spring loaded 510 But it reads 1.5 ohm and on my MVP2 it reads 1.4. Don't have a ohmmeter but it's not much difference.

That is pretty weird, I own the 2s and on my ohm reader it says .74 and my ipv2s reads .7

Certainly worth checking the atty connections always. However in my case it was doing the same on at least six different atty's I tried on it. I did think it was to do with my building originally but I rebuilt one atty making double sure everything was tight and same result. I also cleaned the connectors (atty's and IPV) using contact cleaner with no improvement.

However whatever caused the problem appears to have been fixed, for the moment at least. Been using it for a good few hours now and the most the measured resistance has changed on anything has been 0.1 ohm, which is fine compared to swings from 1.2 up to 3.9 ohms which is the kind of thing happening over the last couple of days. I'd really like to know what on the device could cause this problem so I can fix it if it happens in future

I think the IPV2s has hundredth on the ohm reader and the IPV2 upgrade only does tenths. ( two different models)
.74 vs .7 just like ion the MVP

Strange. I've also noticed that when I unplug from the USB charge and look at the screen it still shows it's changing, as soon as I hit the fire button it switches to battery level. Strange again Lol.

I'm pretty sure that my ipv2s only said .7 but I can check again when I return back to my room. I also have not upgraded it to the 70w either

I haven't noticed that, I'll check it out. I normally leave it to charge till it's full

Yes that's right, the IPV2S only has one decimal point reading on the resistance too.

Sorry I think I was thinking of the IPV3.
