Abstract
A level adjusting circuit which adjusts input pulses from an antenna to a level suitable for determining the number of engine revolutions, is connected in a circuit that connects the antenna with a determining circuit. An optimum adjustment of the determination level by manual operation allows the pulses inputted to the determining circuit to be precisely determined at all times.
