We developed the measurement system, which applied the A/D conversion circuit to the measurement for the acceleration of gravity before, in order to decrease the unprepared artificial mistake, which generated by the measurement in the exercises for students. Since accuracy was inferior in the measured value obtained by the measuring method using this A/D conversion circuit, the research for the improvement was planned, and the measuring method reported here was newly developed. The measurement system developed in order to measure the period of a Boulder's pendulum consists of an oscillating detection circuit developed previously, a periodic detection circuit developed this time, and the calculation programs which accompanies it. In this periodic detection circuit, the microcontroller which detected and processed the state of the port was used for the change of the circuit of a previous A/D conversion circuit. As a result, the measured value of the acceleration of gravity was 9.7988±0.0001 m/sec^2 , and was very appropriate.
