目前不少测量仪器仪表都采用了液晶数字显示，为判断其好坏，本文结合实践，介绍两种简易检测方法。其一，在对液晶数字屏仔细进行外观检查后（外观要求：颜色均匀、无局部变色、无气泡以及无液晶泄漏至笔划以外的现象等），可用万用表作进一步测试，将万用表欧姆档置于RX1k或R At present, many measurement instrumentation are used LCD digital display, to determine its good or bad, this article combines practice, introduce two simple detection methods. First, the LCD digital screen carefully look after inspection (appearance requirements: uniform color, no local discoloration, no bubbles and no liquid crystal leakage to the stroke outside of the phenomenon, etc.), multimeter can be used for further testing, the multimeter ohm will be placed in RX1k or R
