    Im trying to test a signal conditioing circuit for a strain gauge bridge full bride setup. I am going test the circuit with two ac signal inputs to replicate the bridge voltage. Can anyone tell me typical ranges of millistrain so I can change the values of the four resistors to set the bridge voltages?
    Apparently it ranges only in a few millistrains.
    I am using four 350ohm strain gauges.
