3D arm is convenient for observation with digital microscope.

Therefore, even when observing at the same magnification, the same vertical calibration value cannot be used. When measuring by oblique observation, it is necessary to correct for such conditions.
Summary
For accurate measurements by oblique observation, calibration must be performed with the microscope tilted at a 45 degree. However, if you are tilting two axes (tilting not only left and right but also toward you), you need to consider both axes when calibrating.
