The average and instantaneous current flow can be measured using Power Profiler Kit II (PPK2). No modification to series resistors is needed.
Set PPK2 in Ampere Meter mode to measure the power output VOUT and in Source Meter mode to measure power input IBAT.
In Source Meter mode, the power supply for the nPM2100 Evaluation Kit (EK) is from PPK2. In Ampere Meter mode, the power for the EK is from an external source with PPK2 placed in series between the EK and the load. The following table shows further details for the two modes.
| PPK2 measurement mode | Parameters | Description |
|---|---|---|
| Ampere Meter | VOUT | Power outputs measured with the PPK2 in series between the output and the load |
| Source Meter (supply) | IBAT | Power inputs (supplies) measured with PPK2 as the power source into the EK |
For more information on the PPK2, see the Power Profiler Kit II.
