Use a 10x multiplier to convert the micrometer reading to the actual slit opening size. For example,
turning the dial one full revolution starting from the fully closed position will give a reading of 50 on
the micrometer. Using the multiplier, this indicates the micrometer width is set to 500 um. If unsure
of the reading, begin at the fully closed position and add up each full revolution made.
