Measure first, then zoom in and out?

Ahhh, I see, thanks. How can I set the window to something longer than 1 minute (e.g. five minutes, or thirty minutes)?

It is cumulative based on the window you are are looking at, so if you are only looking at the current measurement for 1second, it wil display the charge used for that 1second.

Concur on the outputs in the nRF Connect v3.6.1 GUI. However, the charge I see displayed is not cumulative.

But isn't the charge already displayed? In the power profiler app I can see average, max, time and charge? I am using nRF Connect v3.6.1.

Thanks, Kenneth. Yes indeed, along with multiplying by the voltage to get energy. However, I currently have to export the recorded data and then run the numbers offline (spreadsheet or python). Since the Power Profiler App has ready access to all the variables necessary, it would be most helpful if it calculated and displayed the cumulative energy delivered below the graph of current vs. time.

Wouldn't this be as simple as multiply the average current x time? Though I believe charge is already displayed in the measurement window (Q = I x t).
