Hello Vincent, My apologies for not getting back earlier. At this point, I assume you were able to verify the above sequence. Yes, the above procedure is correct and should work well in your system. I would add that you may need to delay between steps 2 and 3 to make sure the input has settled. This is not much of an issue with an internal short as this will settle very quickly, but applying an external full scale input may require some additional time to settle. The amount of time required can be estimated by measuring the input with a scope if needed. This will give you 1 sigma settling; for settling to within the noise limits, multiply by roughly 16x. Regards, Keith
