Granular than vernier measuring principle of the motion of the screw in the measurements. The first round will be on a rotating micro displacement distance equal pitch (pitch) of the spiral.
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.
The resolution is measured than เวอร์เนีย uses the movement of the screw thread of the measure when turning the micro-mobility, 1 cycles will be equal to remote trekking (Pitch) of the spiral
