Hi,

[quote user=""]1) Is it possible to measure not only discharge current, but also charging current with the PPK (with this setup or another setup) ? [/quote]

No, because the PPK measures the current on external DUTs.

[quote user=""]2) If it cannot be measured, does the PPK allow the charging (will the current flow) ? [/quote]

I am afraid not because that was not in the design purpose or usage. The power only supplies to DK or external board.

[quote user=""]3) Or in the worst case, would it damage the PPK ? Does it make a difference if discharging current is e.g. limited to - 70 mA ? [/quote]

Please see the Power Profiler Kit/introduction:

"The PPK measures power consumption for a connected nRF5 Development Kit or any external board. It
measures current from 1 μA up to 70 mA and gives a detailed picture of the current profile for the user
application."

OK, but if I ensure that +/- 70 mA is not exceeded,- could you comment on my other questions ?

Hi,

Sorry for the late.

Because the maximum DUT admissible current is 70 mA, I am afraid it cannot support your requirement.
