2 dollars 25 cents Look at the line on the vernier scale that lines up with one of the lines on the vernier scale. The next step is reading the micrometer. The whole number increments are on one side of the sleeve, and the half-millimeter increments are on the other. Take all the measurements about the number of revolutions on the small gauge. Here we are going to learn to read the micrometer by figuring out the markings on the Thimble and the Sleeve. Obtain the total by adding the reading of the primary scale, the secondary scale, and the vernier scale. Small gauge measures in tents, and the outer one, in thousands. Look at carefully the index line. 3 dollars 85 cents or .385". 2. There are 6 whole millimeters on the top and a half-millimeter on the bottom. Reading the Sleeve Scale (Primary Scale) The number will help. More simply, read the closest number to the edge of the thimble that’s exposed. Therefore, the way of dial micrometer works is notably different from the mechanical micrometer. Before going further, it’s important to clarify that in this case, we assume that you are using a 1-inch range micrometer. 2 dollars It is also named as spindle. Here are some practice pages. The sleeve of a metric micrometer has markings on the top and the bottom. This is important because different range affects the number of divisions etched on the sleeve scale. Add both the measurements of small gauge and outer one to find the reading of dial indicator. Therefore in this page, we cover how to read a micrometer in those two versions: metric (mm) and imperial (inch). equals The micrometer on top reads 6.50mm. There are markings on the sleeve and also on the thimble of both. It can cause inaccuracy when you take the reading at the wrong angle. If you do not know how to do it, it takes time to wait for your new battery arrived. To learn to read the mike you need to understand the Thimble and the Sleeve. Reading the Sleeve Scale (Primary Scale). They are available in measuring ranges of 0 to 25 mm, 25 to 50 mm, 125 to 150 mm up to 575 to 600 mm. Reading the Thimble Scale (Secondary Scale). We get smaller measurements from the large gauge. .225 - "point two-two-five", What is this reading?  X Research source This practice isn't a necessary step for measuring, but keepi… Except, you use digital ones which you can convert the unit into another easily in no time. It depends on the country where the micrometers will be sold. Read the line on the thimble that coincides with the index line. 2 dollars 50 cents The thimble is set to 0. For example, what are the readings on the micrometers shown below? In the picture below, the Sleeve shows 3 dollars and one quarter (25 cents). Count how many divisions it is from mark 0 of the vernier scale. Read the nearest number to the thimble that’s exposed. .300 - "point three-zero-zero", What is this reading? Use either a clean sheet of paper or soft cloth, and hold it between the anvil and the spindle. Reading a micrometer is not too difficult, but not as simple as we may think of, such as reading a tape measure. If the dial makes further revolution check error for each revolution.
