22. CHECKS AND ADJUSTMENTS

136

• Be careful that the tightening tension is identical for all the adjusting screws.

• Also, do not over-tighten the adjusting screws as this may damage the circular level.

PROCEDURE Checking

1. Carefully level the OS and center a survey point

precisely in the reticle of the optical plummet.

2. Turn the upper part through 180° and check the

position of the survey point in the reticle.

If the surveying point is still centered, no

adjustment is necessary.

If the survey point is no longer centered in the

optical plummet, perform the following adjustment.

PROCEDURE Adjustment

3. Correct half the deviation with the levelling foot

screw.

4. Remove the optical plummet reticle cover.
