The rule that attaches the slide part to place the measuring object is called calipers. Chiefly, it is a tool used in the scene that processes the thing. Rough scales of the scale and the school (main scale) where the vernier (vernier) is detailed are combined, and a small numerical value of calipers can be read by the difference of the scale.
There are an inside diameter, a diameter, and one calipers depth, too and everything can be measured. There is neither of the method to measure by placing, and opening a difference. Because [haka] Sadamu only has to be able to do, it is enough in the drawing though belongs to low performance [namono] as a measuring instrument by accuracy and the display up to 0.005mm the directionthe necessity minimum.
The display method of the measurement result is different in digital calipers and analog calipers. When it is digital calipers, the result is displayed with the liquid crystal display. Because the memory has adhered when it is analog calipers, those who measure it should read the result by himself/herself.
1.The thing to be measured is placed.
2.The thing to be measured is placed. It is understood that it is 8mm here because the scale of 0 of the vernier is 8mm first of all.
3.Next, length is seen with the vernier. The scale of seven of the vernier of the school is exactly suitable for 27mm though the scale of the vernier shifts little by little with the school.
4.If the length seen at the school and the length seen with the vernier are added, the thing to be measured understands and 8.7mm is understood.
