Adjusting outside micrometer?

[Jason280]

I picked up a Fowler 0-1" digit counter disc micrometer, and need to zero the "wheel"...but cannot find a manual online. The digit counter goes to zero with the disc jaws closed, but the drum is at "20". How do I adjust it to get everything at zero with the jaws closed?

This is the model:

Do you have the wrench?

Yeah there's usually a hook spanner wrench and a tiny hole it engages. The collar turns with enough force allowing visual adjustment of the lines.

+1. I attached a pic of what the wrench looks like. Very easy to do once you have the wrench.

I have the wrench, just not the intelligence to know how to adjust it!

Trial and error. Do you have a reference standard? Mine came with one so you could calibrate at open.

No reference standard, just the box and wrench.

Jason, look at this video, it shows how to adjust them.
