about board's current

[Kaito]

hello Now I use the nRF52832's board and I was measuring the current But when the board's power is off and i measured, the current was flowed in the board. Now i am using the oscilloscope. I don't know why flow the current. The picture of that time is shown in below. gyazo.com/a2f35ffdd8d16cba2eeec11ae70ca07d

Thank you in advanced.

Hi, did you connect the scope as described in this guide? infocenter.nordicsemi.com/.../hw_meas_oscilloscope.html

Was your board connected to the USB when you measured? If it was, could you redo the measurements with the USB disconnected, but with a coin cell battery in the battery holder? This would eliminate any noise from the USB, and the coin cell would allow to see if there is leakage.
