万能工具显微镜在长度测量的测试中是最典型、使用范围最广的一种测试仪器,因为它可以测量长度、角度、螺纹等,并且可以对各种形状和位置复杂的产品进行测量,又有较高的精度,所以专门用来解决在长度测量中的各项测试问题。影像法就是工具显微镜一种典型的测量方法。图1为大型工 Universal tool microscope is the most typical and most widely used test instrument in length measurement because it can measure length, angle, thread, etc., and can measure a variety of shapes and positions of complex products, and High accuracy, so specifically designed to solve the length of the measurement of the test problems. Image method is a typical measurement tool microscope. Figure 1 for large workers
