摘　　要：介绍了一种实现变送器响应时间自动测量的方法，该方法是利用微机控制电源、数字多用表及开关，获得变送器随时间变化的输出电压值来实现的，测量精度可达±４ｍ ｓ。In accordance with the fact that it is difficult to measure response time of electrical measuring transducer in electricity management, an approach which can measure response time automatically is proposed in this paper. In this manner the output voltage of electrical measuring transducer which varies with time can be obtained by use of the power source, digital multimeter and switcher which are all controlled by computer. The accuracy of the measurement is ±4ms.
