22. CHECKS AND ADJUSTMENTS
3. Use the fine motion screws to align the target to
point B on a vertical line.
If the target moves parallel to the vertical line,
adjustment is unnecessary. If its movement
deviates from the vertical line, have our service
representative adjust it.
PROCEDURE Check 2: Vertical and horizontal reticle line positions
• Perform check in weak sunlight and no scintillation.
• "Tilt crn" should be se to "Yes (H,V)" and "Coll.crn" to "Yes" in <Obs. condition> while performing
checks.
"20.1 Observation Conditions"
1. Carefully level the instrument.
2. Install a target at a point about 100m in the
horizontal direction from the OS.
3. While the Observation mode screen is displayed
and the telescope is in Face 1, sight the center of
the target correctly and read out the horizontal
angle A1 and the vertical angle B1.
Example:
Horizontal angle A1 = 18° 34' 00"
Vertical angle B1 = 90° 30' 20"
4. While the telescope is in Face 2, sight the center
of the target correctly 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"
