So the no load voltage should be zero, and to accomplish that, I would need to modify the circuit to trim it to zero? I tried googling around but mostly found circuits to balance the bridge. Is that the same? I was assuming the bridge was factory balanced as there is no additional components on the original circuitry from the scale. The leads go strait into the microcontroller under the edge of the sealed black blob.
Any verified examples I could compare my situation to to attempt to zero out my bridge? BTW, the bridge appears to be made of the apposing strain gauges (3 wire each) crossed into the 4 outputs of excitation and sense, both +/-.
Thanks again for helping me with this..
