Explanation:
Detailed explanation-1: -So you need to calibrate your eyepiece graticule with a stage micrometer before making measurements with your graticule. The graticule scale is arbitrary – it represents different lengths for different magnifications, so the scale needs to be calibrated for any new microscope or new magnification.
Detailed explanation-2: -Place a stage micrometer on the stage of the microscope. Line up one of the divisions on the eyepiece graticule with a fixed point on the stage micrometer. Count the number of divisions on the eyepiece graticule that correspond with a set measurement on the stage micrometer. More items
