Power Profiler Kit II - Quit Start - Verify wiring with nRF9160 DK

[Achim Kraus]

According Power Profiler Kit II - Quick Start the PKK2 is connected to the nRF9160 DK with

• PPK2 VIN to P24 VDD_nRF
• PPK2 VOUT to P24 VDD_nRF'
• PPK2 GND to P28

My experience is, that VIN must be connected to VDD_nRF' (incoming from VSUPPLY of nRF910 DK) and VOUT must be connected to VDD_nRF (outgoing VDD_nRF of nRF910 DK). See nRF9160_DK_HW_User_Guide_v1.1.0.pdf, page 40.

The wiring in that quick seems to be exchanged and doesn't work.

Hello,

There are two modes which you can measure current: ampere meter and source meter. 

Pin connection for ampere meter mode is 

   

and source meter mode it is 

Based on the mode pin connection differs and this is the way to set up the PPK with DK for current measurement. 

Thanks.

Thanks, for confirming the wiring.

Not sure, maybe I was not that precise:

The PPK -Quick Start (the Nordic Semiconductor WebSite) seems then to mix it up. Maybe you can report that internally, so that Nordic corrects that Quick Start?
