USB DAQ 6363 measurement bad with several channels

Hi Laurent,

Sorry for the long update.

I really think it's an issue of conditionning. 

The value you're expecting is really low and the noise coming from your system and measured by the board can be some hundreds of microvolts.

You could also try working with other values of shunt resistors, or amplifying your signal first.

Regards
