BQ27Z561EVM-011: Voltage difference between BQ27Z561EVM-011 and Instruments.

Hi, everyone.

I find there is a difference between the voltage measured by BQ27Z561EVM-011 and the one measured by instruments.

Let me show a picture first:

In the picture above, the voltage shown in BqStudio which is measured by BQ27Z561EVM-011 is 3363mA.

The voltage measured by multimeter and electronic load is around 3010mA.

I have already calibrate BQ27Z561EVM-011 before using it.

I would like to ask the possible reason of this voltage difference.

Thank you,

Wenlong
