3.1 Horizontal checking and calibration
(X and Y axis)

3.1.1 Horizontal checking

1. Place the laser on a flat surface 50 or 100 ft. (30m) from a wall.
Position it so that the X 1 is facing the wall.
2. Turn the laser on. After it's level, stop the rotation so that the beam
is a point.
3. Mark the location of the beam.
4. Rotate the laser 180°. After 90 seconds, mark the location of the
beam near the first mark.
5. Both measurements must be at the same place. At 100 ft., the
marks should be no more than 1/8'' apart. At 50 ft., the marks
should be no more than 1/16'' apart. (At 30 meters, no more than
6 mm apart). This is +/- 0.010% leveling accuracy.
6. If the marks are close enough, X axis is within calibration. The
second axis (Y) must then be checked (see Step 7).
If the marks are not close enough, the x axis needs to be re-calibrated
(see instructions below).
7. To check the y axis, turn the laser 90° from Step 4 so that Y 1 is
facing the wall. Repeat the same steps: mark the Y beam, rotate
180°, and mark again. If the marks are more than 1/8'' apart at
100 ft., Y axis should be re-calibrated.

3.1.2 Horizontal calibration

The laser must be calibrated to bring the beam to the centre of the
two marks (Steps 3-4 in 3.1.1). The calibration is easily done using
the laser keypad, remote control, or detector.
X axis calibration
1 . Tu rn the laser off before switching to calibration mode.
Simultaneously press two laser keys, On/Off and auto/man.
2. After a few seconds, release On/Off key.
3. The X LED indicator (23) will blink, then the y LED (21). Release
the auto/man key.
4. The X LED (23) will blink rapidly, indicating the laser is ready to
10
X axis
Y axis Z axis
be calibrated in the X axis. If you have not moved the laser, use the
X marks made in Steps 3 and 4 of 3.1.1 (Horizontal Checking).
5. Mark the spot that's halfway between the two marks.
6. With X 2 facing the marks, bring the laser beam up or down to
the centre mark by using (16) or (17) on the laser keypad or (2) or
(3) on the detector or remote.
7. Next, check Y axis against centre mark. Tu rn the laser 90° so that Y
2 faces the wall. If the beam is not on the centre mark, calibrate Y. If Y
is OK, see «Saving calibration» below.
Y axis calibration
1. To change to Y axis calibration, press (15) on the laser or (4) on
detector or remote.
The Y LED will blink rapidly, indicating that the laser is ready to be
calibrated in the axis.
2. If you have not moved the laser, use the centre mark from above.
Bring the laser beam up or down to that centre spot by using (16) or
(17) on the laser keypad or (2) or (3) on the detector ro remote.
Saving the calibration
The laser is now calibrated in the X and Y axis. Press (14) on key-
pad or (5) on detector or remote to save the calibration data. If you
don't wish to save the calibration, press the On/Off key (24) on the
laser.
3.2 Vertical checking and calibration (Z axis)
3.2.1 Vertical checking
1. Place laser in vertical mode, on a flat surface about 10 ft. away
from a plumb line (plumb bob hanging on a string, at least 8 ft.
high). If you need to calibrate, beam will be easier to see in a dark-
ened room.
2. Use the adjustable feet to rough level the laser.
3. Turn the laser on. Stop the rotation so that the beam is a point.
4. Hold the laser head and move the beam up and down the entire
length of the plumb line by hand. If the beam is slanted, and not
v e rtical like the plumb line, the z axis needs calibration.
3.2.2 Vertical calibration
1 . Tu rn the laser off before switching to calibration mode.
Simultaneously press On/Off and Auto/Man.
