Abstract

PURPOSE:To simplify the measurement of control time and to remarkably reduce the time for time set and adjustment, by providing external terminals for check connected to the output side of an oscillation circuit. CONSTITUTION:An analog type timer consists of a time constant circuit comprising an oscillation circuit 31, a counter circuit 32, a variable resistor 33 and a capacitor 34. The output side of the oscillation circuit 31 is provided with external terminals D, E for check. The output of the counter circuit 32, that is, a control time T has the relation as T=oscillation period T0X frequency dividing ratio, the output of the oscillation circuit 31 is led out with the external terminals D, E and the oscillation period T0 is measured with an oscilloscope, allowing to know the control time T, which is set to a specified time by adjusting a semifixed resistor 33.
