8. Verification of adjustment
Lateral level
Align the theodolite horizontally using the lateral level as described.
Adjust the lateral level in the direction of one adjustment screw.
Turn the device by 180°. Verify whether the bubble is centred.
If the bubble moves away from the centre, move the bubble back
toward the centre after half the distance using the adjustment
screw. Correct remaining errors with the adjustment screw. Check
for transit.
Circular level
To verify the circular level, the instrument must be aligned
horizontally using the lateral level. Now verify whether the circular
level is centred. No adjustment is required if this is the case.
When the bubble moves away from the centre, the circular level
must be centred via the 3 adjustment screws.
