Power Profiler Kit II ( Ampere Mode)-Measuring 300mA Current

I am trying to measure the 300mA system current.

I cut off the system lane and connected Vin, Vout.

And when in ampere mode, the system is not turning ON.


(When I replaced the PPK II with DMM, the system is ON)

How can I know if my PPK2 is broken?

Or do I missing something?
