DEVICE FOR SETTING A NUMERIC DISPLAY |
摘要 |
A device for setting a numeric display (11) comprises a continuously turnable potentiometer (12) 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 (10), 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 (T1 high) of a series of measurement values and for each subsequent measurement value (T2 high) in the series to determine if the difference between the present and the first measurement value exceeds a reference value (Tdiff), in which case the display (11) is operated to increase or decrease its value by one step of a predetermined magnitude. |
