How to use
Before measurement, ensure the anvil and spindle faces are clean and free of debris. Switch on the micrometer and zero it according to the manufacturer's instructions if required. Place the workpiece between the spindle and anvil, close the spindle by turning the thimble or ratchet until firm contact is made, and read the value on the digital display. For repeatable results, use the ratchet or friction thimble to apply a consistent measuring force and record measurements at several points if checking roundness or parallelism.
