Hello All,
I am trying to figure out how i can digitally calibrate my outtput of an instrumentation amplifier connected to a quarter bridge. My Strain gauge sensor is continually varies with temperature through out the day. And sometimes it drifts outside the measurable range which means i loose data. Is there a way i can automatically calibrate the sensor value to 0V output by controlling it digitally. I do not want to do this manually. As it is drifts through the night. I have attached my schematics. Could someone please advise?
