高精度全功能游标卡尺High-precision full-function vernier caliper

高精度全功能游标卡尺High-precision full-function vernier caliper 卡扣安装，无需胶水Snap-on installation, no glue required 读数方法： 1.读取主体刻度 读取游标为“0”之前的刻度如图示为29mm 2.读取游标刻度 观察游标刻度与主体刻度那个刻度齐平，如图所示 游标刻度“2”与主体刻度齐平，所以+0.2mm  即此时读数为29.2mm 1. Read the main body scale The scale before the vernier is "0" is 29mm as shown in the figure 2. Read the vernier scale Observe that the vernier scale is flush with the main body scale, as shown in the figure The vernier scale "2" is flush with the main body scale, so +0.2mm, that is, the reading at this time is 29.2mm 安装图示
