Hi, Kenneth is currently on vacation, so I have taken over the ticket.

In the newest version of the Power Profiler app (v4.0.0), under "Advanced configuration", you can find these options:

Best regards,

thanks for you replay ,

Is there some way for us to eliminate this spikes to get the actual current value? for example By software or hardware configuring setting?

Just to confirm. Yes, the PPK2 range switching causes some spikes which are very high. The peaks are not part of the actual current consumption, but a side-effect from the automatic measurement resistor switching (switching to a higher ampere range). Please disregard the peaks you see when current increase rapidly.

Hello,

I did not have time to ask internally today, will try to follow up when I am back in office. My assumption here is that the in-rush peaks you see are when the PPK change measurement range (when switching from measuring low to high current).
