介绍一种电动转撤机智能检测仪,它不仅可以测量直流电机的起动电流和工作电流,而且能判断电机卡死及断相故障;具有打印接口,为一、二级测试提供了方便。文章介绍了仪器的功能、测量原理及硬件组成,并给出了8755的编程方法。 This paper introduces a kind of electric tester, which not only can measure the starting current and working current of the DC motor, but also can judge the motor stuck and the phase failure. It has the printing interface, which provides the convenience for the first and the second test. The article introduces the function of the instrument, measuring principle and hardware composition, and gives the programming method of 8755.
