I was changing the contact point on a new depth gage. I think the spindle may have rotated. The contact point is no longer flush to the base. It might be off by .02845". The depth gage (547-258S) is a Mitutoyo with a digimatic indicator (543-392BD). Can I adjust the spindle without damaging the indicator? I don't want to send it out for repair if I can help it. It's brand new.
