Micrometers are the instruments that are used for measuring the thickness, diameters, and depth of slots with very small distances. Measurements are done by reading the scale. These basic measurement instruments that are used in almost each and every industry is composed of a frame, anvil, barrel, lock nut, screw, spindle, thimble, and ratchet top. In this post, we will discuss the importance of calibration and a list of websites with free online training for Micrometer Calibration.

In our other post, we shared the basic steps for the calibration of a micrometer. If you are looking for online training videos/webinars to clear your basics about calibration, we are here to help you. While doing the calibration for a micrometer,  TUR should be at least 4:1. It states that the standard accuracy must be greater than a 4:1 ratio over the accuracy of the gage being calibrated. In our next post, we will discuss guidelines for calibration on micrometers.

Mitutoyo has a bunch of free online training videos related to calibration. Apart from that, they have some really good paid training with in-depth knowledge about the calibration of various instruments. In the link given below, it presents the calibration method for outside micrometers based on the American standard ASME B89.1.13-2013.

This one is the free video available on the official website of Mitutoyo. It shows step by step instructions on the calibration of outside micrometers. It is a very detailed video. For more videos regarding calibration of most commonly used equipment in the industry, do visit the official website of Mitutoyo.

Certified Credentials for General Calibration, Micrometers and Calipers

The Mitutoyo Institute of Metrology is providing an opportunity to earn certified credentials in dimensional calibration. The online training videos are available for free and the fee is for credentials. These videos by the Institute of Metrology includes basic inspection techniques, principles of dimensional metrology, calibration methods, and GD&T. The first online course, “General Calibration Concepts, Micrometers and Calipers” is available online for free.

Level 1 credentials: Theory, $75†
Level 2 credentials: Performance, $250*
