ＳＺ－２型数字电路学习机是我实验室最新研制出的功能增强型的电子技术学习机，不仅保持了原学习机的优点，而且把以往的面包板插接方式，改为可叠插自锁紧接插件和管针式插座方式，克服了面包板接触不良和使用寿命短的弊病，并使更换元件、查找故障、调试参数更为方便。实验 SZ-2 digital circuit learning machine is newly developed by our laboratory function-enhanced electronic technology learning machine, not only to maintain the advantages of the original learning machine, and the past breadboard plug-in method can be stacked to insert Locking connector and pipe socket way, to overcome the shortcomings of poor breadboard contact and short service life, and to replace components, find fault, debugging parameters more convenient. experiment
