摘要
介绍了利用电子计数器在时间继电器延迟时间内对标准频率源的输出信号进行累加计数 ,从而实现时间继电器延迟时间精确测量的方法 。
The method to realize the delay time accuracy measurement of time relay by using electronic counter making accumulative total of output signals of the standard frequency source in the delay time of the time relay is presented, at the same time the uncertainty of measurement is elialuated.
