Hi,

I am using AD620 with whetstone bridge configuration.I set gain 127 and gain resistor value is 400 E also I attached schematic in attachment.I don't get linear change in output.In schematic R2 resistor get vary from 100 E to 230 E but i don't get change output as per resistance vary. I get only two voltage level i.e 3,84 V when R2 is 230 E and -0.10 V when R2 is 100 E.also I don't get any effect when change pot at op07. Please  chck schematic and give me suggestion.

 

Thank you
