23. CHECKS AND ADJUSTMENTS
With this option you can check the perpendicularity of the reticle and the horizontal/vertical positions
of reticle lines.

• Check the telescope reticle by manually sighting the target.
PROCEDURE Check 1: Perpendicularity of the reticle to the horizontal axis
1. Carefully level the instrument.
2. Align a clearly visible target (the edge of a roof for
example) on point A of the reticle line.
3. Use the jogging knobs 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 your Sokkia
service representative adjust it.
PROCEDURE Check 2: Vertical and horizontal reticle line positions
1. Carefully level the instrument.
2. Install a target at a point about 100m in the
horizontal direction from the SRX.
3. While the Meas mode screen is displayed and the
telescope is in face left, sight the center of the
target 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"
