Reading Calipers卡尺培训 Nov.30, 2007 What are Calipers? Calipers are mechanical measuring devices. 卡尺是机械测量设备 Calipers are primarily used to verify the dimensions of a machined part. 卡尺主要用来测量机加工的零件 Types of Calipers A caliper has two jaws, one fixed, the other sliding, a thumb wheel with ridged edges for easier operation, and most have a thumb screw that locks for precise settings. 卡尺有两个卡爪,其中一个固定，另外个滑动。凸起的拇指转动轮能使操作更方便。而且常有个蝶形螺钉用来锁定而到达精确设定。 There are three basic types of calipers:有三种典型的卡尺 Vernier 游标 Dial表盘式 Digital数显式 Vernier Calipers Vernier calipers have two scales for indicating measurements. 游标卡尺有两个标尺用来显示测量 Dial Calipers Dial calipers are similar to Vernier calipers but have a dial gage for indicating measurements. 表盘卡尺与游标卡尺相似，但是使用表盘标尺来显示测量值 Digital Calipers Digital calipers work the same as dial and vernier calipers, plus they offer a display for easy-to-see readings; inch-to-metric conversion; and the ability to set zero from any position. 数显卡尺工作原理和表盘和游标卡尺相似，而且它还有显示窗用来方便读数。公英制的转换，任意处的归零设定。 Measuring with Calipers Prior to using a caliper, inspect the jaws for cleanliness and damage (if damaged, do not use).使用卡尺前需要检查卡爪的清洁和好坏（如果已经损坏了就不能使用） For digital calipers, check that the digital reading is zero with the jaws closed. 数显卡尺在卡爪卡紧后数显示值读数在零点 For a dial caliper, rotate the bezel so that the needle points to 0.表盘卡尺在卡尺卡紧后转动表盘来使指针指向零位  Measuring with Calipers A caliper can take four kinds of measurements: outside, inside, depth, and step. 卡尺能用来进行四种类型的测量 Any caliper, whether it is a vernier caliper, dial caliper or digital caliper, can take these measurements. 以上三种游标卡尺都能进行以上四种类型的测量  Measuring with Calipers Outside Measurements外侧测量 Outside measurements are the most basic you can do with a caliper. 外侧测量是卡尺最通用的测量 Slide the jaws open, place the caliper over the object to be measured, and slide the jaws until they contact the work piece. 卡尺卡紧零件 Read the measurement. 读取测量值  Measuring with Calipers Outside Measurements外侧测量 If
