摘要
应用智能型多功能数/模和模/数转换单元、电压跟随单元、取样单元以及可调电压信号放大单元,通过USB接口与计算机的数据交换并配合编程软件,实现了自动跟踪接触电阻随电流增大的变化趋势。
An equipment which is made up of an intelligent multi-function D/A,A/D convertor,voltage follower,sampling unit,voltage amplify selector, connected with computer by USB interface, cooperated with LabView software, and for searching the law that the trend of contact resistance follows the changed current was developed.
