Need confirmation from those with an evolv dna 30 + kfl + multimeter

[Silver5656]

So I noticed that while charging, both my rdna and authentic hana modz v3 give me a very small continuous shock if ONE of my lips (usually the lower one) touches the kfl while the device is charging. I have explained in more detail in the rdna thread. But basically using either the dc mA or the ac mA setting on my multimeter (not sure which one to use, dont know much about multimeters) I get a readout of about .02 dc mA or .35 ac mA when I probe the kfl while the rdna/hana is charging. This only happens when charging. I would appreciate if someone else with this combo could use their multimeter to test it. I've tried several chargers, several cables, several outlets, and even my car charger, and always get a reading. This kind of disturbs me. Thanks!

Make sure you are using a 5v 1 amp Wall Plug a 5v 2.1 Amp wall plug can cause this while charging.

this happens using all the chargers in my house, which includes an iPhone charger (which is 5v 1amp), even my logitech charger which is a 5v .25 amp

Can't replicate this on the rDNA using 10W iPad charger

well since i cant upload a vid unless i link from another site, here is a before and after pic i just took showing the issue

Seems to me this has something to do with grounding.


In the second picture; the black lead; where does it go? You didnt mention it and you didn't think it important, but if you look at THAT, that's where he shocking comes from in a sense.


If your body is not grounded in some way, when you put the thing to your lips, you will not get shocked.
Same thing as when a bird flies and lands on an overhead electrical live wire, it doesn't get shocked because it is not grounded.

Then perhaps the more important question is how high a voltage are you running?

 

[Silver5656]

The reading varies depending on where the black lead touches. If I touch my body it goes to 5.0 ac mA, if i touch something I know is grounded the reading does not change (by much, could be how i'm using the leads) I just find it disturbing that there is anything at all on the outside of the atty, no? There is zero reading when it is not charging

 

[Silver5656]

oh and you are totally correct, if i touch the black lead to my lower lip i do feel a charge, and the meter goes up to 5.25ish ac mA

 

[Silver5656]

anywhere from 4.98 to 5.01 v according to my usb reader, and this is with pretty much any charger you can think of

I have tried several outlets, both at work at home, several atty's, several chargers, several cables, all have similar results, and in 15 min i will know if this works on a buddy's authentic hana plus authentic kfl

It is disturbing that you get a shock.

It's not entirely surprising that you have a voltage on the outside of the atty; the higher the voltages involved, the higher one might expect the voltage you might pick up on the outside of the atty; that's why I asked how high a voltage you are running.

Ideally, the atty should really be grounded I would have expected, but based on what you're experiencing it seems it is not. -- oh; tht's something you can experiment yourself: ground off the atty with a wire to give a better pathway instead of current passing though you; it won't solve the problem but it would prove what the problem is.

ok, just confirmed, my buddy's authentic kfl also produces a shock. he said he's never noticed it before, but when i told him how to reproduce it, he feels it. His reading is almost identical to my ehpro's so its not just a clone issue
