Abstract

PURPOSE: To obtain high setting precision by providing a circuit which sets a variable operational constant by a potentiometer and then by putting the potentiometer into setting operation over a supervision over the number display of a digital display unit.
CONSTITUTION: Reference value Ec of reference voltage generating part 1, input signals Ei1WEi4, and set values Es1WEs8 from potentiometers PM1WPM8 of variable operational constant setter circuit 3 are sequentially selected by input multiplexer 4, A/D-converted by signal converter 5 and then stored in RAM10. Input values are processed according to procedures stored in ROMs 11 and 12 and then stored in the output register of RAM10. Those are outputted by CPU9 after being D/A-converted by circuit 5. To set a variable operational constant, a fixed channel is selected by switch 17 to let display LED come on, and PM is adjusted over a supervision over a number on data diaplay unit 18. Thus, high setting precision can be obtained regardless of the setting of PM.
