FRDM33771 BMS not working properly

I am using the FRDM33771 together with the battery emulator. 

I want to test cell balancing and measure current for SOC however when I enable the cell balancing I see no difference regarding the voltages and the current measurement seems wrong also. 

When I enable MEAS_ISENSE I can't change the voltage with the emulator and it keeps -157.286 mV.

Do I have to connect an external shunt resistor or is it already inside the emulator.

See the attachment for further information. 


Thank you
