The use of the vernier scale allowed the scale to be read to one minute, so improved the marketability of the instrument.
22.
The angle of the sight is then read from the scale on the arc, making use of the micrometer or vernier scale provided.
23.
The additional digit of these micrometers is obtained by finding the line on the sleeve vernier scale which exactly coincides with one on the thimble.

While working in Wisconsin, where there were large deposits of iron ore, Burt experienced great difficulty in using his standard vernier scale compass.
25.
All axes are indexed to . 0001 " via a vernier scale on the handwheels, with higher accuracy available with the use of measuring bars.
26.
The main scale reading is determined by the rightmost tick on the main scale that is to the left of the zero tick on the vernier scale.
27.
The 0.02 mm inscription indicates the caliper's precision and is just the width that corresponds to the smallest interval on the vernier scale.
28.
The user then reads the finer vernier scale ( see diagram ), which measures between the smallest graduations on the fixed scale providing much greater accuracy.
29.
A Vernier scale on caliper may have a least count of 0.1 mm while a micrometer may have least count of 0.01 mm.
30.
A graduated dial and, often, a vernier scale enable the operator to position the table, and thus the work affixed to it with great accuracy.
