Measure average current with an ampere meter

nRF54L15 DK Hardware

The average current drawn by the application nRF54L15 SoC can be measured using an ampere meter. This method monitors the current in series with the nRF device. A true Root Mean Square (RMS) ampere meter is recommended.

  1. Prepare the nRF54L15 DK as described in Set up the DK.
  2. Connect an ampere meter between the pins of header P6 as shown in the following figure.
  3. Set the average timing of the ampere meter to a long interval, such as 1 s or longer.
  4. Set the dynamic range of the ampere meter between 1 µA and 15 mA, so that it is wide enough to provide accurate measurements.
