(二)游标卡尺的使用与维护 游标卡尺的使用如图15,使用游标卡尺应注意以下事项: 使用游标卡尺前应首先检查其零位。当两量爪测量面接触时,观察游标零线与主尺零线是否对齐。 根据被测面的形状选用量爪的适当部位进行测量。若测量轴径和外表面宽
(B) the use and maintenance of vernier caliper vernier caliper as shown in Figure 15, the use of vernier caliper should note the following: vernier caliper should be used before checking its zero. When the two claws measuring surface contact, observe the cursor zero line and the main scale zero line alignment. According to the shape of the measured surface selection of appropriate parts of the amount of claw measurements. If measuring shaft diameter and outer surface width
