Using Axis-Alignment and Grade-Reverse Modes
How Axis-Alignment Mode Works
Axis-alignment mode works by changing grade in the aligned-axis direction
and cross-axis directions then monitoring the elevation changes of the laser
beam at the receiver via the radio remote control. The desired axis-alignment
angle can then be calculated and the internal grade system “rotated”
electronically to align the simulated grade axis to the desired point.
Important Things to Know about Automatic Axis Alignment
Automatic Axis Alignment
• Replaces the alignment scope and vernier base traditionally used
• Can be done from any side of any axis of the laser, even if grade is dialed
into the opposite axis that’s being aligned
• Automatically adjusts the direction the grade axis is pointing to the
receiver/remote location
• Electronically simulates rotating the laser on its base to match the hub
For Proper Operation
• The desired grades must be entered into the laser
• The receiver must be at the correct alignment point
• The receiver must be between 60 feet (20 m) and 500 feet (150 m) from
the laser
For Best Accuracy
• Set up the laser to align to the elevation reference the farthest away (such
as the centerline of the road)
• If the hubs are equally distant, align to the hub with the smallest amount
of grade
