Hey folks.
I purchased a set of Shars micrometers with separate insturments from 1 to 6.
I have been practicing with them to get a feel for them by measuring an item with the micrometer and then with a pair of digital calipers that I have.
I was getting a difference of .005 +/_ and I tried measuring the 4 standard that came with the set and ended up with the same error.
After a bit of head scratching I found the little hole on the back and found that the tiny spanner wrench fit it and I was able to zero the mic to the standard.
A couple of questions: Do these micrometers need to be checked every time before use and what factor does temperature have in doing measurements?
Thanks,
Brad
