Measure VBAT, VBUS, and VOUT using an ampere meter

Measure the current with an ampere meter by placing the ampere meter in series with the source or load and the probe point.

Make sure you have prepared the Evaluation Kit (EK) as described in Prepare for VBAT, VBUS, and VOUT current measurements.

  1. Connect an ampere meter to the probe-point of interest, depending on the measurement case prepared initially.
  2. Read the current value on the ampere meter.
The following figure shows the VBAT current-measurement case, with the ampere meter connected between P1 pins 1 and 2.
