Click on 'Check Connection' button. If connections are right, use range sliders inside 'Components' box to vary the input voltages.
Click on 'Show Output' button to view the output on DMM.
Click on 'Add to table' button and calculate the output voltage using the formula:
V_o = - (V₁ + V₂ + V₃)
to add calculations to the table.
