Review on Mitutoyo 293 348 30 Digimatic Micrometer IP65: Precision Measurement at its Finest by Randy Montiel

I bought 2 of these - one for use in the tech lab at work and one for home use. I'm not impressed with electronic micrometers. If you're measuring something small, the origin will zero out pretty well. But after measuring something by about an inch, half the time the origin will be off by half a tenth to a tenth. I'm not new to microns, so it's not an inept user or uncertainty about the cleanliness of carbide surfaces. They replaced a 30 year old Mitutoyo mechanical tenth mic that fell off (I still kick myself for that). If I had to do it all over again, I'd go with a pair of mechanical tenths instead. They cost less money and a mechanical zero requires a stationary drum to spin, but the zero holds up very well. The digital readout on this mic is handy, and it's handy to have readings in inches or metric with the same mic. However, the strange origin confuses me.
