When an unbalance exists in conductance, the vector addition results in
both of the rectified voltages becoming slightly less negative, and by the
same amount.
The resultant dc voltages applied to the grids of V301 are
therefore of equal value, and no change occurs in the anode circuit as a
result.
Thus, using the phase detector (ZERO CENTER), the bridge can
be balanced for capacitance regardless of differences in conductance.
Figure 5 illustrates the basic bridge equations.
