23. CHECKS AND ADJUSTMENTS
4. While the telescope is in face right, sight the
center of the target and read out the horizontal
angle A2 and the vertical angle B2.
Example:
Horizontal angle A2 = 198° 34' 20"
Vertical angle
B2 = 269° 30' 00"
5. Do the calculations: A2-A1 and B2+B1
If A2-A1 is within 180°±20"and B2(B1 is within
360°±20", adjustment is unnecessary.
Example:A2-A1 (Horizontal angle)
=198° 34' 20"- 18° 34' 00"
=180° 00' 20"
B2-B1 (Vertical angle)
=269° 30' 00" + 90° 30' 20"
=360° 00' 20"
If the difference is large even after repeating the
check 2 or 3 times, have your Sokkia service
representative perform the adjustment.
