External battery STM32 power shield

Hi, I want to ask a question. I have STM32 power monitor shield and is it possible to measure current without powering the device by the shield? I want to use battery to power the device and measure the current drown from battery.

Is anybody can tell about connection of EVALSTPM33 with 2 current channels(with shunt as well as CT)

the schematic for STPM33 is atttached.
