PPK2 showing crazy current even if it is OFF

[zyghom]

Just see the screen shot - PPK2 is OFF yet it shows 200mA

Hi there,

Can you specify what you mean by the PPK2 is OFF? From the screenshot I can see that you have connected the serial USB cable to the PPK2 and have enabled the power output.

Hi Jared, are you saying 11 Amps is what PPK2 can deliver? and max 22A?

hi Jared,

the crazy readings were not disappearing even when I disconnected ESP32, Only solved it when I closed the app and disconnected usb and then started new connection and application start.

But this was not the first time so I expect this to happen again and they I will follow what you said

[Jared]

Ok, great.

Please notify me if it happens often.

regards
Jared

it happens again:

power is off, but the graph shows crazy values

and as you asked: I disconnected the load - no change at all

what I will have to do it is to eject PPK2, disconnect from USB, restart the software and it will be back good again

this issue is repeating all the time however I am not able to narrow down what causes it.

However, it seems that it is enough to restore the proper behaviour of PPK2 by simply clicking this button - no need to close the program and disconnect PPK2 from USB.

but the solution is for another few measurements and the problem repeats - I find it super annoying ...

[zyghom]

no, sometimes "eject" button does not make it working - so back to square 1: close the app, disconnect PPK2 from usb, start from the beginning and only then it works

Hi Zygfryd,

Are you able to reproduce this with a windows computer and the same PPK2?

Jared

[zyghom]

no, my last Windows experience was 10 years ago (and I don't miss Windows) ;-)

[Jared]

Hehe, I understand.

Could you try to downgrade the Power Profiler version by downloading the previous version here and follow this guide.

regards

Jared

[zyghom]

downloaded, testing

will let you know Jared

[zyghom]

so far so good but it is too short to say

however, I see that the new version is much more different than I thought - see the screen from both versions - see how the new version extended the Y scale from 0, while 3.4.5 is excellent and the chart is where it should be - not from 0 but from min to max of the current it was drawn
