Need a help on how to go about building a Laboratory scale using strain gages
I need to build a scale with a working range of 2 to 200 gm, an accuracy of at least 2 gm, footprint of no more that 16 in sq, and use no more that 6 strain gages.
I believe I need to set up the strain gages in wheatstone bridge format. But that's about all i know. What kind of calculations do i need, where do i start, then what's the next step?
