The average current drawn by the nRF52832 System on Chip (SoC) can be measured using an ampere meter. This method monitors the current in series with the nRF device. A true ampere meter is recommended.
Make sure you have prepared the Development Kit (DK) as described in Set up the DK.
Connect an ampere meter between the pins of connector P22 as shown in
the following figure.
To measure the average current drawn by the nRF52832 SoC, perform the following steps.:
- Set the average timing of the ampere meter to a long interval, such as 1 s or longer.
- Set the dynamic range of the ampere meter between 1 uA and 15 mA, so that it is wide enough to provide accurate measurements.
