A method of calibrating a dialysis machine to determine the volume of a dialysate flow path of the machine including a dialysate preparation tank includes the steps of introducing a known quantity of electrically conductive chemicals into the dialysate preparation tank, filling the dialysate solution flow path with water, mixing the chemicals with water to form a solution, measuring the conductivity of the solution, calculating the system volume (Vsys) according to the relation: Vsys=M/(a1r+b1) where M is the mass in grams of the chemicals, a1 and b1 are a coefficient of linearity and a constant of linearity, respectively, for the chemicals and r is the measured conductivity of the solution.
