If the tilt angle shown on the display shifts from tilt angle 0° (zero point), the instrument is not correctly
levelled. This will adversely affect angle measurement.
Perform the following procedure to cancel the tilt zero point error.
PROCEDURE Checking and adjusting
1. Carefully level the OS. If necessary, repeat the
procedures to check and adjust the bubble levels.
2. Select "Inst. cons." in <Configuration>
3. Select "Tilt offset".
4. Level the instrument until the X/Y tilt angles are
±1’. Wait a few seconds for the display to
stabilize, then read the current tilt angle in the X
(sighting) direction and Y (horizontal axis)
direction.
