Hello. I red this article http://zone.ni.com/devzone/cda/tut/p/id/8909 about determination the accuracy of strain gage measurements. Can somebody tell me please is it true that we must add half-bridge tolerance when we calculate the accuracy of half-bridge? I have some doubts, because the accuracy of full-bridge and a half-bridge are differ in almost 60 times! Maybe someone have references of this article? Or someone can explain me how exactly to calculate the accuracy of half-bridge.
