5. Mark point B on the target (see Fig. 3).
When point B is at the same height as point A, then the Y level is
accurately calibrated.
Where this is not the case, the unit must be recalibrated.
4.1.2 Checking of calibration - Y axis
1. Take the fine adjustment of vials with the levelling screws.
2. Mark the point A on the target (see Fig. 2).
3. Turn the unit by 180° without readjusting the height.
4. Adjust the levels with the levelling screws.
Note
Mark either levelling screw A or B as a reference screw. Align the unit
only with the other levelling screws.
4.1.3 Calibration - Y axis
1. Put the laser exactly onto the centre between points A and B (distance
½ a) with the levelling screws (do not use the reference screw).
2. Calibrate the vial with the calibrating screws (use a SW 2.5 Allen
wrench).
4.1.3 Checking and calibration - X axis
Proceed in the same way as for checking and calibration of the Y axis, but
align the laser beam over the X vial.
