Z axis: Calibrate vertical vial
Note: Prior to any Z axis calibration, make sure that the
horizontal vials (X and Y vials) have been correctly calibrated.
1. Set the unit up horizontally between two targets. (Remove
the protective cap at the side of the
bubble vial before calibrating)
2. Mark points A1 and B1 on the
targets.
3. Set the unit up vertically in the
vicinity of target A.
4. The laser strikes the first target and marks point A2 at the
same time.
5. Measure the distance between A1 and A2 (a).
6. Transfer the distance measured (a) to target B.
7. Adjust the laser beam with the levelling screw to the height
of B2.
8. If the bubble does not indicate
levelled, gently raise or lower either
end of the vial as needed to center
the bubble. Replace caps.

Technical Data
4. Turn the unit 180° without changing the
tripod
or surface height.
5. Using the same two levelling screws,
relevel unit.
6. Mark point B on the target.
If point B is at the same height as
point A, then the Y level is accurately
calibrated. If this is not the case, the
unit must be recalibrated.
Re-calibration of the Y axis:
1. Adjust the levelling screws (do not
use the reference screw) until the laser
is exactly centered between points A
and B. Take time to be as precise as
possible.
2. Remove the caps on the ends of the
bubble vial and reset the vial with the
calibrating screws using the hex
wrench supplied.
3. Gently raise or lower either end of
the vial as needed to center the
bubble. Replace caps.
Checking and re-calibration - X
axis
Proceed in the same way as for
checking and calibration of the Y axis
but turn the unit 90°, to align the laser
beam over the X vial.
