In Reply to: 6" Dial Calipers with counter? posted by Kurt IA on December 25, 2018 at 13:21:55:
Digital Dial Calipers: turn on, clean blade and jaws, close, press the 'ZERO' button. Test with a few opening and closings so it geos back to zero when closed. You are now calibrated. Measure your part. If in doubt, keep a Jo-Blok or two handy to verify calibration. I don't trust digital calipers and mics. Forget any counter. Always best to have an alternate measuring instrument.
