An improved method and apparatus for adjusting the space between an adjustable anode and a cathode in an electrolytic cell wherein current measurements and voltage measurements are obtained for conductors to the anode sets and compared with predetermined standards for the same conductors and anode sets. Measurement of deviation from the predetermined standards are used to determine the direction of anode adjustment. A digital computer operably connected to motor drive means adapted to raise or lower anode sets upon appropriate electric signals from the computer is a preferred embodiment of this invention. In a preferred embodiment, potential incipient short circuits are detected and avoided by the improvement which comprises: (a) obtaining the difference between two successive current signals for a selected conductor and doubling the difference to obtain a total current difference, DELTA t, (b) obtaining the difference between two successive current signals for the conductor adjacent to the selected conductor and adding the difference for each adjacent conductor, to obtain an adjacent total current difference, DELTA a, (c) subtracting DELTA a from DELTA t to obtain a remainder R for the selected conductor, and (d) raising the selected anode when R exceeds DELTA t by more than about 0.5 percent.
