I am getting a faint high pitched noise from my new Provari v2 when it fires. Other than that, it works great. Anyone else getting this?

The high pitched whine is normal..
Its from the power regulating circuitry.. AFAIK, the ProVaris use PWM (Pulse width modulation) to regulate the power going to the atty, and all you're hearing is the power switching on and off (thousands of times a second)
Its normal, all of my provaris do it with some attys / cartos, at certain voltages.
Enjoy your new V2!

Hmmm. My v1 doesn't do it, but if it is normal, then i can live with it. I do like the v2, however, I havent had the chance to push a dcc up to 5v yet. Soon. I really like the blue display.
Thanks for the info.

The V1s will do it too, usually at the higher voltages..
It seems like mine have quieted down after months of use.. Hmm..
Regardless.. Yeah, its completely normal.
Cheers!

From everything I've seen and read I'd have to disagree about the PWM, Pulse Width Modulation turns the voltage on and off hundreds of times per second to maintain a set voltage, but the Provari sends out a constant voltage no PWM that I've seen (from reviews). You are probably hearing some form of coil-whine, nothing to be concerned about as long as your Provari works, if you start having issues, well you get a standard 1 year warranty anyway xD.

Well, Finally got off my ...., and tested it.. I agree, its not PWM, but its not smooth DC either..
There is a wave to the signal... This is with my provari turned up to 4.5V..
Weird..

Actually, I had this same problem and I was able to fix it. Clean the threads on your endcap and inside the tube, it's dust on the threads causing an improper ground. Also, make sure you screw it all the way down, firmly.
This took me 4 hours and going insane to finally figure out
EDIT: Forgot to mention, this was with a V1 a few weeks ago, and it had built up grime on the threads on the extended cap. I just used a microfiber cloth to get everything out, and a small dab of no-alox.

I will give this a shot, but this device is about 5 hours old. I can't imagine it is dirty, but maybe it has some styrofoam from the packing material or something. Thank you for the suggestion.

From ProVari FAQ :

It must be filtered then, as thats not like any PWM output I've ever seen.
PWM would make sense from an engineering standpoint, but how they go from there to the wave shown above, I don't know..

PWM feeds the MosFET which works with the Inductor, caps, and a diode to produce what you see. Straight PWM would only allow voltage to drop and not boost.
You sound like the man who will let us know.
EDIT: or someone posting whilst I am ....

I cleaned the threads on the end cap and in the tube, and the high pitched buzz disappeared. I was surprised to find a bit of grit on the threads.
