Let's take a look at the size of the caliper. Vernier caliper is a more precise measuring tool, which is most used in measurement. It is usually used to measure the workpiece with high precision. It can measure the outer linear size, width and height of the workpiece, and some can also be used to measure the depth of the groove. If divided according to the scale value of the vernier, the vernier caliper is divided into three types: 0.1, 0.05 and 0.02mm. The reading method can be divided into three steps; 1) Read the whole millimeter according to the nearest scale on the main ruler to the left of the zero line of the auxiliary ruler; 2) According to the zero line of the auxiliary ruler, multiply the number of scribed lines aligned with the scale on the main ruler by 0.02 to read the decimal; 3) Add up the integer and decimal parts above to form the overall size. （KaCheZenMeKanCheCun）
