Micrometer Simulator is an app that used to learn about how to read Micrometer device measurement result. Teacher, student or any user else can do measurement virtually before they go to the real laboratory, and do measurement with real object. With this app they no need more time to learn how to read micrometer scale, and directly can do measurement with the real object.
Just drag and press the Micrometer Object to do measurement Virtually. You can change the virtual object that you want to measure with Change Object menu and try to read the measurement result on the Scale object. Have fun, and let try it!
