ABSTRACT A device for setting a numeric display comprises a continuously turnable potentiometer by which the setting area can be repeatedly passed through by turning in the same direction. The potentiometer and the display are connected to a computer, preferably a microcomputer. The computer is arranged to repeatedly sense the instantaneous resistance value of the potentiometer or a parameter representing said value. Further, the computer is arranged to store the first one of a series of measurement values and for each subsequent measurement value in the series to determine if the difference between the present and the first measurement value exceeds a reference value, in which case the display is operated to increase or decrease its value by one step of a predetermined magnitude.
