HI,
Opamp used has Differential input and output
We are giving Load cell input to the differential inputs of the opamp.
Observations:
1) Output of the load cell when measured without connecting and when connected to the opamp circuit varies.
why so? there is some drop in the load cell output when connected.
what are the possible cases for this?
2)when the feedback resistors values are increased there is no drop. how does this work?
how to fix the feedback resistor value?? do you have any guidelines
