Measured over the woenia's spiral motion of the measuring. When the spin cycle phase will be 1 Micro's motion is equal to the length of the screw (Pitch) fraud.
Measured using Vernier finely threaded principles of measuring. When the Microsoft's first round will be moving distance equal pitch (Pitch) of the helix.
measure resolution than vernier, use the principle of mobile helix measuring. When the rotary micro company 1 around will be moving range of distances. Pitch (Pitch) of spiral
