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。
直流测速发电机性能指标
1.线性误差
在其工作的转速范围内,实际输出电压与理想输出电压的差值 m U ? 与理想输出电压 之比称为线性误差。
2.线性工作转速
在允许的线性误差范围内的电枢转速称为线性工作转速。亦即测速发电机的额定转速。
3.输出斜率
在额定的励磁条件下,单位转速所产生的输出电压称为输出斜率。此值越大越好。增大负载电阻,可提高输出斜率。
4.负载电阻
保证输出特性在允许误差范围内的负载电阻值。在使用时,接到电枢两端的电阻应不小于此值。
5.不灵敏区
由于换向器与电刷间的接触压降,而导致测速发电机在低转速时,其输出电压很低,几乎为零,这个转速范围称为不灵敏区。
6.输出电压的不对称度
在相同转速下,测速发电机正反转时的输出电压值之差 与两者平均值 之比称为输出电压的不对称度。一般不对称度为 0.35%~2%。
7.纹波系数
在一定转速下,输出电压中交流分量的峰值与直流分量之比称为纹波系数。
