常规调节步进电机转速的方法分为以下几种：
一、换向器电机调速
优点：①具有交流同步电机结构简单和直流电机良好的调速性能; ②低速时用电源电压、高速时用步进电机反电势自然换流，运行可靠; ③无附加转差损耗，效率高，适用于高速大容量同步电机的启动和调速。缺点：过载能力较低，原有电机的容量不能充分发挥。
二、定子调压调速
优点：①线路简单，装置体积小，价格便宜; ②使用、维修方便。缺点：①调速过程中增加转差损耗，此损耗使转子发热，效率较低; ②调速范围比较小; ③要求采用高转差电机，比如特殊设计的力矩电机，所以特性较软，一般适用于55kW以下的异步电机。
三、转子串电阻调速
优点：①技术要求较低，易于掌握; ②设备费用低; ③无电磁谐波干扰。缺点：①串铸铁电阻只能进行有级调速。若用液体电阻进行无级调速，则维护、保养要求较高; ②调速过程中附加的转差功率全部转化为所串电阻发热形式的损耗，效率低。 ③调速范围不大。

两量爪与待测物的接触不宜过紧。不能使被夹紧的物体在量爪内挪动。读数时，视线应与尺面垂直。如需固定读数，可用紧固螺钉将游标固定在尺身上，防止滑动。实际测量时，对同一长度应多测几次，取其平均值来消除偶然。卡尺的维护方法运行检查在每天使用之前，要先检查游标卡尺的零刻度是否对齐，刻度是否清晰可见，挪动是否顺畅，是则该卡尺可正常使用，否则需将该卡尺进行维修或更换新的计量有效的卡尺，并按运行检查规定中的仪器失效处理方法进行。
