We have one of these: Mitutoyo Bench Comparator
but with an extra dial off the left side that reads down to 20 millionths of an inch.
I haven't been able to find a proper instruction manual for it either - online or at the shop.
Problem is, I'm pretty sure not sure I'm using it right. This is what I've been told to do, and been doing:
Set the 0-1" dial to 0 and lock it so it can't be moved from there.
Adjust the range using the right most knob until the anvils close, and the other 2 indicators read 0. Adjust them if necessary
Adjust the range again (using the right most knob) until it closes on the master gage block stack you're going to compare against, and the other 2 indicators read 0. If necessary, make adjustments to the indicators. Pull down on the lever to remove the gage blocks, put your work piece in, let go of the lever. Take your reading. This leaves me confused about what the purpose of that 0-1" dial is to begin with if you never turn it / change it from 0, and how do you know how much force to use when zeroing it? I can turn the range knob just a little bit tighter or looser get a different reading, adjust the indicators.. and get 0 again This, combined with the fact that I'm getting measurements I know are incorrect, leads me to believe I"m doing it horribly wrong
Thanks again for helping a confused novice. You guys are incredibly kind and knowledgable I hope I'll be able to some day contribute!
