by measuring something with a known constant thickness, a dollar bill or something. A 'gage block' is best
How can I calibrate a micrometer without the use of gage blocks. Any adjustments on the device?
Gauge block.
I personally have know idea but tectronics? tektronics? will calibrate it for about $70.00
Calibrating micrometers: For quick reference the supplied test piece can be used. For calibrating a micrometer, gauge blocks are used.
Because that can be calibrated out of the bar can be fixed.
a tiny ruler that you know the measurements of, and you use it to calibrate the ocular lens of a microscope
First calibrate the micrometer by dialing the spindle to zero and adjusting the anvil until it is flush against the spindle. Measure the screw until the ratchet begins to click and take the first reading. This reading can then be compared to a machining book to verify the pitch diameter.

The ocular micrometer is inside the ocular lens, it will not change size when the objectives are changed. Therefore, each objective lens must be calibrated separately. Ocular micrometers have no units on them - they are like a ruler with marks but no numbers. In order to use one to measure something under a microscope, you must assign numbers to the marks. This is done by looking through your OCULAR micrometer at a STAGE micrometer mounted on a slide. The stage micrometer is just a ruler with fixed known distances, so you can use it to tell how far apart marks are on the ocular micrometer. This has to be done because the marks on the ocular micrometer are different distances apart depending on the magnification used on the microscope. It must be calibrated for each objective.

A micrometer is equal to exactly 1 micrometer.
