Negative current value in power profiling

[arnsoft]

hardware: power profile kit rev 1.1, nrf52840DK

mode: power profiling with DK

I am power profiling my application and found that if there is no current in the system, power profiler shows around -36uA current. is there any way to adjust the zero.

How is the PPK configured? Are all the switches in the DK position?

[arnsoft]

Yes. Both DUT  select and power select are in DK position.

And did you cut the solder bridge SB40?

What about the DK. SW9 in VDD and SW6 in DEFAULT position, right?

What happens if you put the DUT select in external position?

What do you mean with "no current in the system". Are you putting the nRF chip to sleep?
