Hello! i am using the attached strain gauge amplifier circuit for my project. i am unable to have the output at zero under no-strain condition. I am trying to adjust the trimmers VR1 and VR2 for this purpose but to no avail. As a result i am having negative values which is not at all what i require. Also i need to feed the output signal of the amplifier to a microcontroller but the signal fluctuates too much. Can anyone please help me through the circuit and for processing the signal from the amplifier? Thanks!
