Most likely you can just leave it in the normal reset position (press the "reset switch levels" button). If you notice distorted plots, you may need to play around with the switch levels to stop rapid switching between the different ranges.

Think you very much, Bjorn.

I want ask question 3 again, You mean I don't need to set it? The software will automatically adjust, right?

1) I believe you are correct. You do not need to cut SB9 or short SB 11 or SB12 if you are measuring external HW.

2) The way you have set the external HW up in Figure 1, the nrf52 DK will power the PPK board. The PPK onboard regulator then powers the external HW. Are you wondering how to power your external HW after you have completed the power profiling? This might be correct, but I would double check & consult the documentation for your external HW.

3) See this link for more info.

4) I do not believe you need to recalibrate your PPK (see page 24 of the PPK User Guide for more info).

5) See Chapter 8 Upgrading your firmware of the PPK User Guide for more info related to this.

6) I do not fully understand the question. Could you rephrase it please?

7) See this devzone answer.

8) Not sure why this is the case.
