I work in the Inspection Department of a medium-sized Machine Shop. One of my duties is to make sure all the measuring tools in the shop read accurately. We calibrate most tools annually, and they usually need little or no adjustment from year to year.
This particular Micrometer, however, a 0-1" Indicating (Pressure) Mic made by VIS (Poland), was last calibrated in February of 2011, and is now somehow off by .075 inches. This is over 10 times the amount you can adjust it by simply turning the sleeve.
Is anyone familiar with these mics? Or have any idea how this could happen?
