We investigate the low-frequency quantum transport properties of a three-probe mesoscopic conductor. The static transmission coefficients and emittance matrix of the system were computed by explicitly evaluating the various partial density of states (PDOS). We studied the finite-size effect of the scattering volume on the global PDOS. By increasing the scattering volume we observed a gradual improvement in the agreement of the total DOS as computed externally or locally. Our numerical data permit a particular fitting form of the finite-size effect. Finally, we propose a method to solve the finite-size problem.
