Here's a tip I haven't seen mentioned. For your 0-1" mic. They are very sensitive. The anvil faces need to be cleaned before checking zero.
The best way to do this is to close the mic down on a piece of paper using the ratchet to tighten. Then just slide the paper through. If it reads .0002 off and you do this it'll come right back to zero.
And never ever store the 0-1 mic with the anvil closed. always back off for storage.
This one is 15 years old, just cleaned it via paper and checked zero. I don't recall a single time this mic did not reacquire zero after cleaning via paper.

I use the Mitutoyo Absolutes and have Swiss made B&S backups. Sadly it appears the B&S are no longer made in Switzerland.
I've had the B&S for about 25 years & it was used daily for 15 years. No longer do this stuff as a profession so it mostly lives in the garage on the lathe or mill now.
