nRF9160 DK v1.0.0

Using a current meter for current measurement

The current drawn by the nRF9160 can be measured using a current meter.

Before you start, make sure you have prepared the Development Kit (DK) as described in section Preparing the development kit for current measurements.
To connect the current meter in series with the nRF9160, connect the current meter to the pins on connector P22.

Note: Use a high-speed, high-dynamic-range ampere meter for the best and most reliable measurements. Current range switching in the current meter may affect the power supply to the nRF9160. High speed and bandwidth are required to detect rapid changes in the current consumption in the nRF9160.
