Abstract
PURPOSE:To obtain a measured value which is satisfactory in its accuracy, resolution and response property, by operating each counting value of a counter of an input pulse and a counter of a clock pulse, and deriving a digital measured value. CONSTITUTION:When a state of a digital outputting circuit D/O is on, a CPU3 receives interruption, only one interruption is made to pass through a measuring period, and each value of a pulse counter 1 and a clock counter 2 is read. The CPU3 executes operation by use of a clock pulse as to measured values of the previous time and the present time, in the next measured value operating and processing routine, and derives a digital measured value operating and processing routine, and derives a digital measured value. When this measured value operation ends, the ciruit D/O is turned on and the next interruption is received.
