The experiment about random error statistical regularity is an important experiment in the 《Experiment of College Physics》. With the application of opto-electrical switch,the accuracy of measurement of the experiment is improved ,and the time of experiment is retrenched. According to characteristics of experiment,it is found that the main error of random error is come from the mode of single pendulum's swing,the accuracy of the experimen apparatus and person's reaction time. To counter these case,some measures are put forward,and then the accuracy of measurement is improved.
