I'm making project where I would like to read from stain gauge sensor. It will use only one 1k ohm (or 350 ohm) strain gauge and 3 dummy resistors to complete bridge (1k or 348 ohm). I'd lik to feed signal from bridge to A8237 ICF amplifier and I'd like to know what is better way of remiving initial bridge offset Like there: First Way
What I mean by sesnod way is that I'll connect DAC output with RA to one of bridge signals and adjust voltage.
Which one is better?
