Measuring current
Figure 23: Current measurement with an oscilloscope
Some tips to reduce noise:
• Use probes with 1× attenuation
• Enable averaging mode to reduce random noise
• Enable high resolution function if available
Use a minimum of 200 kSa/s (one sample every 5 µs) to get the correct average current measurement.
5.3 Using an ampere meter for current measurement
The average current drawn by the nRF52832 SoC can be measured using an ampere meter. This method
monitors the current in series with the nRF device.
Make sure you have prepared the DK as described in Preparing the DK on page 25.
Connect an ampere meter between the pins of connector P22 as shown in the following figure.
