Then, read the value shown on the thimble scale.
The thimble scale of a metric micrometer has a range of 0.5mm (one complete revolution), with each increment representing 0.01mm, and usually numbered in 0.05mm steps. The value is the lowest number that aligns best with the index line on the sleeve scale.
If the index line falls between two values, the reading will be the number immediately below the index line.
If this is the case, you should estimate the final part of the measurement or, if your micrometer has one, consult the vernier scale.
Here, the thimble scale is showing 0.11mm.
