calibration.
Checking Accuracy and Calibration- Y Axis
To check the Y axis, mount the Green Auto Leveling Rotary Laser Level l on a
tripod and place it approximately 100 feet (30m) away from the wall, with the Y+
quadrant facing the wall (Fig. 31); follow steps 2 through 4 of “
Checking
Accuracy -X Axis
”. Calibration as in “
Calibration- X Axis
”, choosing the “Yad” to
calibrate and adjusting “+” and “-“input as necessary within the Y+ quadrant (Fig.
34a and Fig. 34b).
Checking Accuracy - Z Axis
1. To check the Z axis, place the Green Auto Leveling Rotary Laser Level on its
back (display facing up), 100 feet (30m) from a wall on a flat, level surface
(Fig. 35).
2. Hang a plumb line down the wall at least 8 feet long.
3. Press the
button to turn on the level, allow the Green Auto Leveling
Rotary Laser Level l to self-level. If necessary, adjust the rotation speed to
easily view the laser beam on the wall.
4. Orient the Green Auto Leveling Rotary Laser Level parallel to the wall and
attempt to align the laser with your plumb line. If the laser line does not align
with the plumb line, then calibration is necessary.
