Document Type and Number:
Japanese Patent JPS5845675
Kind Code:
B2
Abstract:
PURPOSE:To reduce integration time and improve the accuracy of measurement by making use of the pulse width slightly longer than the time corresponding to the maximum measuring level as the sampling time of an integrating circuit. CONSTITUTION:A sampling time setting circuit 14 which obtains the synchronizing signal from a synchronizing circuit 4 and sets the pulse width slightly longer than the time corresponding to the maximum measuring level as sampling time is provided. The output of the sampling time setting circuit 14 is used to turn ON and OFF the switch circuit 9 which is connected to the input side of an integrating circuit 10. The output of the integrating circuit 10 is displayed in a display circuit 12.
