Operation
Grade Swap
The grade in the X-axis can easily be
swapped from positive to negative in
the
Grade Entry by Digit
screen.
Align the Y-axis (level) to the center
line, the X-axis or cross axis grade can
be made to fall to the right or lefthand
side simply by changing the +/- sign on
the display.
Grade Matching
In Direct Grade Entry mode the
movement of the leveling mechanism
moves at the same speed as the grade
counters.
To match an existing slope, set up the
laser over the known gradebreak
(base) of the slope, and align the cross
axis (level only) of the laser to the end
of the slope with both control points
parallel to the direction of grade.
Adjust the Rod-Eye receiver on your
grade rod for the elevation of the laser
at the gradebreak next to the laser.
Move the grade rod to a point on the
slope that is too be matched. Then,
dial grade into the laser until the Rod-
Eye indicates an on-grade reading.
The percent of grade in the display is
now equal to the grade being matched.
