The average current drawn by the nRF7002 EBII can be measured using an ampere meter. This method monitors the current in series with the nRF device.
Make sure you have prepared the nRF7002 EBII as
described in Set up the nRF7002 EBII.
Connect an ampere meter between the pins of connector P10 as shown in the following
figure.
Figure 1. Current measurement with an ampere meter
For the following conditions, an ampere meter measures the average current drawn by
the nRF7002 EBII.
- The nRF7002 EBII is in a state where it draws a constant current for the activity on the device changing load current, like Wi-Fi® connection events, the activity is repeated continuously, and has a short cycle time (less than 100 ms) so that the ampere meter averages whole load cycles and not parts of the cycle.
- The dynamic range of the ampere meter is wide enough to give accurate measurements from 1 µA to 15 mA.
For best results, use a true Root Mean Square (RMS) ampere meter.
