I am sure some machinist is going to shake his head when he reads this….
So I own maybe 4 different sets of digital calipers. I have a set of slot calipers, I have a set of Mitutoyo and at least 2 other random calipers. On hot days I often find they all give CRAZY readings. I am getting ready to invest in some old school dial calipers.
Does anyone have a clear idea what goes wrong with the digitals on hot days. Is it moisture / grease on my hands getting on the back of the rail?
