Hi,
did you do some calculations?
With a 10k resistor and +/-0.000005% tolerance ...
--> then you talk about +/-50mOhms.
Lets assume your wheatstone bridge is optimized for those 10kOhms (symmetric) and it is powered with 5.0V
--> then you talk about a tolerance of +/-1,25nA or 12,5uV bridge mismatch.
Do you have the knowledge and the equippment to measure those signals without introducing higher errors (like with thermocouple effects).
To be honest: I don´t have..
