Power Profiler Kit 2 with nRF52 DK different value for ampere and source mode.

[Dominic Wunderlin]

I do measure different values for source and ampere mode. On the nRF52 DK.

Source Mode: disconnect SB9, Power Switch is off. Vout from PPK2 connected to nRF current measurement pin1. Power mode enabled. supply voltage at 3V from PPK2.

Ampere Mode: disconnect SB9, Power Switch is on. Vout from PPK2 connected to nRF current measurement pin1 and Vin from PPK2 connected to nRF current measurement pin2. Power output enabled. nRF DK connected with 


For source mode I measure like 700 uA and for ampere mode I measure 6 uA. Is there something wrong in my setup? Because both measurment method should display the same.

That is one option and there are others but these options are covered in the DK user guide.I personally always power the kits as it is the easiest way and you retain all features like LED, buttons+++

The HW files for all the kits are on the nordicsemi.com website on the page for the kit in question.
