I have a guy at work that says that the resolution of a lined scale (such as a stage micrometer or steel ruler) should be included as a line item in the uncertainty calculation (because the resolution of the device under test is to be included). While this makes sense for measuring instruments with variable displays, I don't think it does for fixed increment linear scales. He is going to dig up documents that are supposed to back up his position, so I am hoping someone can point me to a specific document (and where in the doc!) that says a linear scale resolution does not apply.
Thanks!
Thanks!
