摘要
设计了单片机对正温度系数热敏电阻的电流 -时间测试系统。系统完成对正温度系数热敏电阻产生的瞬变非正弦电流的初始、阻尼电流及稳态电流的峰峰值的测量 ,峰峰值达到 2 .5级以上 。
The design of PTC current time testing system are introduce through the use of single chip in this paper,This system can finish peak values measurement of initial current,damped current and steady state current of instantaneously changing non sine current which produced by PTC.
