Check
1. Set object A at about 100 meters away the same height as the instrument, and make the vertical angle
with ± 3° . Then level and center the instrument and turn on the power
2. Sight obje
ct A in FaceI and read the horizontal angle value. (e.g.: Horizontal angle L=10°13′10″).
3. Loosen the vertical and horizontal clamp screws and rotate the telescope. Sight object A in Face
