As a reference you could use schematic loadcell from propeller tester project https://workspace.circuitmaker.com/Projects/Details/Mateusz-buleks/Propellertester. For automatic test you should add 3 resistors from LC_AVDD to LC_GND, and connect signals A- and A+ to resistor in the middle. DOUT should be connectet to SPI and to some GPIO by resistor.
