- Page 7 UM2633 Sensor current consumption measurement Sensor current consumption measurement X-NUCLEO-IKS02A1 expansion board is equipped with jumpers which allow separate current consumption measurement of each sensor. To measure current consumption, connect an ammeter to the appropriate jumper. As the sensors have very low current consumption, you should set a suitable range and use an ammeter with low burden voltage.
