摘要
介绍采用三端稳压器 W31 7代换 1 2脚稳压器 WA71 5 ,代换时应注意控制信号的相位逻辑要正确。通过恰当的器件代换 ,使日渐陈旧的 75 1 G分光光度计重新投入了使用。
The phase logic of the control signal ought to be correct when replacing a twelve pin regulator WA715 with a triple pin regulator W317. By replacement of appropriate electronic components, the obsolete equipments as 751G spectrophotometer could be renewed.
