When measuring current with the Power Profiler Kit (PPK), some adjustments are needed to optimize the measurement accuracy. The nRF5 DK must be prepared for the measurement.
Power Profiler Kit use with nRF5 DK
When the PPK is used with an nRF5 DK, it is recommended to use the Power select (SW4) switch in the DK position.
Current measurement on external DUTs
When measuring current on external devices, it is important to keep in mind that large filtering capacitors, which may be present on the DUT circuit, will smooth out the variations in power consumption.
