7.
After completing the X calibration, press the H.I. key (3) to
change the axis and to calibrate the Y axis. (On the remote, press
the double arrow key >>l)
8.
If the Y axis doesn’t have to be calibrated, press MAN key (5)
to save the calibration you’ve just made on X axis. (On remote, use
key with the small dot.)
If you are not sure of the calibration, don’t save it and turn the
laser off using the On/Off key.
4.2.3 Checking Y axis
1.
Rotate the laser 90 degrees so that Y’ is facing the wall.
2.
Mark the location of the center of the beam.
3.
Rotate the laser 180 degrees so that Y faces the wall.
4.
Mark the location of the beam center near the first mark.
5.
At 100 ft., the marks should be no more than 1/4" apart
(at 30m, no more than 6 mm apart). This is within the stated
accuracy of ± 1/8” at 100 ft. (± 0.010%).
6.
If the marks are close enough, Y axis is within calibration.
Proceed to “Final X to Y Check.” If the marks are not close enough,
Y axis needs to be calibrated.
4.2.4 Calibrating Y axis
The laser must be calibrated to bring the beam to the center of the
two Y marks.
If you are still in calibration mode from the X axis, turn Y towards
the wall and press the H.I. key to change to the Y axis. When the Y
LED blinks slowly, it’s ready to be calibrated in Y axis.
If you’re no longer in calibration mode
1.
Turn off the laser.
2.
Hold the MAN (5) key. While holding, momentarily press the ON key.
3.
After the LEDs blink in sequence, release the MAN (5) key.
4.
Select the Y axis by pressing the HI key on the laser keypad
(on the remote, press the double arrow key >>l ).
amount (1/32" at 150' or 1mm at 100m). After pressing
the key, the LED will blink rapidly as the laser reacts.
Wait until the LED returns to a slow blink to proceed.
4.2 Horizontal checking and calibration
4.2.1 Checking X axis
1.
Place the laser on a flat surface or tripod 100 ft. (30 m) away from
a wall. Position so that X’ (noted on top of laser) is facing the wall.
2.
Turn on the laser.
3.
Mark the location of the center of the beam. If it’s too bright to
see the beam, use the detector.
4.
Rotate the laser 180 degrees so that X faces the wall.
5.
Mark the location of the center of the beam near the first mark
so that both marks are in line, one above the other.
6.
At 100 ft., the marks should be no more than 1/4" apart
(at 30m, no more than 6 mm apart). This is within the stated
accuracy of ± 1/8” at 100 ft. (± 0.010%).
7.
If the marks are close enough, X axis is within calibration. The
second axis Y must then be checked (see later section).
If the marks are not close enough, the X axis needs to be calibrated.
4.2.2 Calibrating X axis
The laser must be calibrated to bring the beam to the center of the
two X marks. Read "Calibration Overview" before proceeding.
1.
Turn off the laser.
2.
Hold the MAN (5) key. While holding, momentarily press the
ON key.
3.
After the LEDs blink in sequence, release the MAN (5) key.
4.
X LED will blink rapidly, indicating leveling. When the LED
blinks slowly, the laser is ready to calibrate.
5.
If you have not moved the laser, use the X marks made in
previous steps of “Checking X axis”.
6.
Use arrows on the keypad to move beam up or down to the
halfway mark. If the X axis is toward the wall with the marks, use
the ^ key (8) to raise beam, and the v key (9) to lower beam.
