对于室外高层观光电梯的安装，不应采用线锤做样线，应采用激光导轨校正仪安装导轨，则有效避免了室外风导致线锤的移位。导轨安装完成后，如果出现问题，很难补救，所以在安装时，必须遵守安装工艺，一次安装调整成功。在使用过程中，因为导轨安装质量而导致电梯运行振动剧烈，则需要搭设井架，重新安装导轨，工作量大，工期长。不搭设井架，对导轨进行大修，则无法达到技术标准要求。现场安装环境比较复杂，工人的技能水平参差不齐，部分新工艺，新方法，虽然在试验塔测试合格，但是在现场应用还是有差别。

每次测量前必须调零，换欧姆挡后也要调零。被测电阻不能带电，若电路有电容器，应先将电容器放电。c。测大电阻时，不能用手接触导电部分，否则会给汲J量结杲带来严重误差。d。万用表的电流是从“—”端流出的，即“—”端为内附电池的正极，“＋”端为内附电池的负极。e。测晶体管电阻时应将测量量程放在R×100或R×1k挡。若用R×1或R×10挡测量可能会烧坏晶体管，若用R×10k挡测量，则有可能会击穿晶体管。
