An automatic initial approximation system for a scanning tunneling microscope is presented. The device includes a dc motor that is fed by pulses, so that it performs as a stepping motor. A full description of the circuit is given. It is much simpler than the circuit for a true stepping motor, and it is designed to stop motion as soon as a tunneling current appears, thereby avoiding a tip crash.
