Hi;
I have just purchased a set of Moore and Wright Imperial Micrometers.
Now I need practice using and understanding how to read them.
I found a pretty handy video
But I need a little more help.
Here is a pic of my Micrometer (this is the 2 -3"). I have marked what I think are the correct graduations for reading the measurement, but what are the graduations labelled with a Question Mark?
I read this as 2.819?
One more question - It would appear that a 2 - 3" Micrometer can measure over 3" so how can you tell by looking at the scale that the reading is under or over 3 inches?
Next I need figure out how to read it to parts of a thousand?
