12. need to measure a tolerance that is less than 0.002″), most machinists will turn to a Micrometer Reading. lab experiment how to use measuring tools (Vernier Caliper, Micrometer Screw Gauge and Dial. count and add in reading which is noted from main scale. A micrometer screw gauge is used for measuring dimensions smaller than those measured by the vernier calipers. If such a wrench is not available to adjust the zero position of the gauge, first take a reading with the micrometer jaws closed and no paper between the jaws, and subtract this zero reading from the final paper thickness measurement. Typically, the frame is used to mount a micrometer. Enjoy the videos and music you love, upload original content, and share it all with friends, family, and the world on YouTube. We will be using a Mitutoyo micrometer as an example. A standard Vernier caliper has a precision of 0.1 mm or 0.05 mm whereas a micrometer has an accuracy of 0.01 mm when we talk about digital calipers the reading becomes 0.01, the same as a micrometer. Reading … This Java applet will help you to understand how to read a vernier scale. What is the reading? (The scales have been enlarged for easier reading.) A micrometer is one of the instruments used to measure objects of various small sizes. When you are measuring your object only count the exposed marks up to the edge of the thimble.

How to use measuring tools (Vernier Caliper, Micrometer Screw Gauge and Dial. There are three classifications based on how to read the caliper: 1) Vernier caliper, 2) Dial caliper, and 3) Digital caliper. Tip: If the half mm increment is showing on the primary scale, add 0.5mm to the total reading. Therefore, the measurement in the image is 7.14 mm. Read the sleeve: Follow the same instructions as step 1 above. Reading a Metric Micrometer. Figure 1 : The reading here is 15.8 mm. ClampThis clamp is used during measurement reading and locks the object being measured in place for accurate reading. It has a precision of 0.01 mm and if you ever aspire to make something with tight tolerance you will probably need to use it. Vernier micrometer. The index line is also located on the sleeve for measurement readings. When a pair of calipers just isn’t accurate enough (i.e. She is a Certified SOLIDWORKS Associate, Marketo Certified Expert, and is passionate about education and training. The first one uses a vernier scale, while the second one uses a dial gauge, while the third one uses electronic components.Each of them looks different and has a different working mechanism. Be sure to check out MISUMI’s line of Mitutoyo measuring instruments from micrometers to surface roughness testers online. Required fields are marked *. Reading a micrometer manually is actually very enjoyable, especially once you have been familiar with. It use to measure internal gaps/internal daimeter of an object. Clean the anvil and spindle before beginning. TOTAL READING .226" Taking a Reading on a .0001" Micrometer: To read to one ten-thousandth requires an additional scale called the "Vernier" scale. Read the following Vernier caliper measurements. Reading a metric micrometer is similar to a imperial micrometer. A Vernier caliper has two rulers: the main scale and the sliding Vernier scale. 2. FrameThe frame is typically U-shaped. There are a variety of standards available to select from. Video Explanation For accurate readings, the micrometer measures best when mounted to avoid any unnecessary heat while being handled. Thus a measurement of .617 inches would be obtained by reading .600 on the main scale, and then adding 0.017 as determined by the dial (as shown in the image).
