As mentioned in the documentation, the scale factor for EEG values from integer to Volts is:

Scale Factor (Volts/count) = 1.2 Volts * 8388607.0 * 1.5 * 51.0;

I am not sure why it was changed from

scale_fac_uVolts_per_count = 1200 * 8388607.0 * 1.5 * 51.0

to the following,

scale_fac_uVolts_per_count = 1200 / (8388607.0 * 1.5 * 51.0)

in commit 2e58c21 (If anybody can direct me to the resource, I would really appreciate that)

But, the issue I believe is in the value 1200, if we wish to get values in uVs then shouldn't 1.2 be multiplied with 10^6 i.e. the resultant formulation should be

scale_fac_uVolts_per_count = 1200000 / (8388607.0 * 1.5 * 51.0)
