Quick start

In this quick start, the Power Profiler Kit II (PPK2) measures current on the nRF9160 DK v0.9.0 or later.

1. Prepare the nRF9160 DK for current measurements by doing some modifications to the Development Kit (DK). See the nRF9160 DK User Guide for instructions on how to do this.
   Note: If you are using a different DK, see Preparing a DK for current measurement for more information.
2. Connect the PPK2 to the DK with a 4-pin measurement cable using the following pins:
   • PPK2 VIN to P22 VDD_nRF'
   • PPK2 VOUT to P22 VDD_nRF
   • PPK2 GND to P21
3. Connect the DK to a computer using a micro-USB cable.
