HOW TO READ A MICROMETER

INITIAL ADJUSTMENTS
• Before taking a reading, verify that the instrument is set to zero. For
micrometers from 0 to 1" (25mm), carefully clean the measuring
surfaces (1) and bring them together to start the reading. On
micrometers over 1" (25mm), use the "standard" with the ends
properly cleaned.
• If necessary, adjust the micrometer to zero, insert the spanner wrench
in the small slot of the sleeve (7) and turn the sleeve until the line on
the sleeve (8) coincides with the zero line on the thimble (5). When
the micrometer resolution is 0.001mm, adjust the zero through the
vernier zero line (4).
