JColvin Posted November 28, 2018 Share Posted November 28, 2018 Hi @victory460, I don't know if you realized this already, but these two voltage references serve a very similar functionality to the ones that you pointed out on your other thread, that is, the references provide clean inputs for the analog to digital converters to get accurate measurements (and to make sure that the gain adjustment from +/- 20V to 0 to 3.0V inputs are accurate). Thanks, JColvin Link to comment Share on other sites More sharing options...
