Zero Point
the zero position of the origin of some frame of reference. In opticomechanical measuring instruments and in the scale of values of microscopes and rulers, the zero point is an imaginary point or gradation that corresponds to the zero indicator of the reading mechanism. The zero point can vary in these instruments because of particular design features or because of various external forces (temperature, pressure). The zero point is determined by special research or by observation.
