The current drawn by the nRF9160 DK can be measured using a current meter.
To connect the current meter in series with the nRF9160 DK, 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 DK. High speed and bandwidth are required to detect rapid changes in the current consumption in the nRF9160 DK.
