Abstract
PURPOSE:To realize the numeral set system in which the setting of numerals is possible by variable resistors and the numeral information of high accuracy can be set, only when the means instructing the setting of numeral is operated. CONSTITUTION:When the power supply is applied, DC voltage +V is charged to the capacitor 12 via the variable resistor 11. When the switch 15 is depressed, DC voltage V is fed to the operational control section 2, and trigger signal is given to the base of the transistor 13. Then, the transistor 13 is conductive to discharge the charge of the capacitor 12. When the wave shape circuit 14 detects that the potential at the junction point of the capacitor 12 is more than the potential predetermined, the signal of logic ''1'' is given to the operational control section 2. Thus, the Y register 18 stops counting. To the display unit 19, the digital value related to the period when the capacitor 12 starts charging until it reaches a given potential is indicated.
