PPK2 showing crazy current even if it is OFF

[zyghom]

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

[Jared]

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?

[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

[Jared]

Hi Zygfryd,

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

regards

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

Hi,

There is a new update out that should address your issue. Can you see if you're able to reproduce the issue with v3.5.3?

Just upgraded successfully, will let you know while using if there problem continues 

However, do we need the bold lines? Do we need to be traced even while using the PPK2?

just asking ;-)
