A simple, rapid procedure for the determination of the accelerating voltage of a transmission electron microscope is described, which involves the measurement of the ratio of two easily found distances in the Kikuchi pattern near the [111] zone of a silicon crystal. Using enlarged prints the accuracy of voltage determination is around 0.2%, and in good conditions, direct viewing of the flourescent screen gives an accuracy of better than 1%. Data are given for 5% variation from nominal voltages of 100, 120, and 200 kV.
