current mode is mAmp (indicated by an LED). As the current sensor reuses the same
hardware as used in voltage measurement module, you need to connect the signal from
the shunt resistor with +-0.5 V channel:

Experiment
1. Connect SHUNT and ± 0.5 V input together.
2. Connect any external circuit (in this example a 100 Ohm resistor is used), powering it
from the LabBoard +5 V output, but instead of connecting negative end to ground,
connect it to SHUNT ground pin.
3. Using right select button switch into mAmp mode.
4. Observe that it measures close to 5 mA.
