If when measuring the vertical angle of target A at telescope position normal (direct) and reverse
settings, the amount of normal and reverse measurements combined is other than 360° (ZENITH-0),
half of the difference from 360° is the error amount from corrected 0 setting. Carry out adjustment. As
adjustment for vertical angle 0 setting is the criteria for determining instrument coordinate origin, use
