Checking and Adjusting
Y-axis calibration
1. To change to Y-axis calibration, press (15) on the laser or (11) on ZDR300.
The Y LED will blink rapidly, indicating that the laser is ready to be cali-
brated in the axis.
2. If you have not moved the laser, use the center mark from above. Bring
the laser beam up or down to that center spot by using (17) or (16) on the
laser keypad or (2) or (3) on the ZDR300.
Saving the cali-
bration
The laser is now calibrated in the X and Y-axis. Press (14) on keypad or (10)
on the ZDR300 to save the calibration data. If you don't wish to save the cali-
bration, press the On/Off key (24) on the laser.
4.2 Vertical Checking/Calibration (Z Axis)
4.2.1 Vertical Checking
Vertical
checking, step by
step
1. Place laser in vertical mode, on a flat surface about 3 m away from a plumb
line (plumb bob hanging on a string, at least 2.5 m high). If you need to
calibrate, beam will be easier to see in a darkened room.
2. Use the adjustable feet to rough level the laser to adjust the top bubble
vial.
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 vertical like the
plumb line, the Z-axis needs calibration.
