Amplifying load cell signal with AD623 problem!
Hello folk! I am having some trouble with this. I have set up the circuit. Thing is, when i put a 1K resistor between pins 1 and 8, i am supposed to get a gain of 100, instead i am getting a gain of 50. If i put 500ohm resistor, instead of getting a gain of 200, i am getting a gain of 100. What is going on here? My load cell is a bridge type. im getting an output in the mVs so i know my load cell is working. Just the amplification part. Note that the load cell and ad623 have the same ground and the reference is grounded too[0V]. Whats happening? any help appreciated. Diagram is attached.
