摘要
研究一种Windows XP下的PTCR性能测试仪。该测试仪采用计算机并行口进行控制和读取数据,能够测量PTCR的动作时间和不动作电流,为PTCR生产中特性的测试提供了一种有效的自动化手段。
A kind of test system of PTCR in Windows XP is researched and designed. This system adopts parallel port of computer to control and get datum. Operating time and non-operating current of PTCR can be measured in this system. And it provides an automatic method of testing PTCR characters in the PTCR process of producing.
