BrainBitSignalData Value Units

Hi!

According to the docs, the values of T3, T4, O1, O2 of BrainBitSignalData should be read in volts (V). If so, then the values read from the sensor vary around 100mV:

    142mV!!            133mV               149mV              137mV

       36mV                39mV                51mV                59mV

However, the typical range of EEG signal is around 100uV:

Thus,

What are the actual units? And what is the correct way to interpret the data stored in BrainBitSignalData?
