Setup of a manual level laser requires
the operator to manually level the unit
by using the units' screws and bubble
vials.
Self-leveling lasers automatically find
and maintain level within a specified
range. Only rough leveling is required
upon setup. Self-leveling flat plane
lasers use either a
Wire
Hung Compensator or
Electronic Servo Motors.
The Single and Dual Slope Lasers find
and maintain level within a specified
range. You
can also dial in a desired slope, turn the unit
on and the electronic servo leveling
motors automatically maintain
that slope. The unit will shut off if the
laser is disturbed to prevent elevation
errors.

Slope Match is tilting a
Manual FLAT PLANE
Laser or a
Self-Leveling
FLAT PLANE Laser
in the manual mode to achieve a single slope.
How do I achieve a slope with a
FLAT
PLANE Laser?
Determine
the height of the laser at your first bench mark using a Grade
Rod Receiver. Place the Grade Rod Receiver at the same height
over your second bench mark.
Using a
LGA Laser Grade Adapter,
one of the tripod
legs or
if equipped use the raise and lower
buttons on the FLAT PLANE laser to
tilt the laser beam. Match the laser "on grade" signal from the first bench
mark to the second. You now have a consistent slope matched from
the first bench mark to the second bench mark.
CAUTION:
Unlike the
Self-Leveling Single and Dual Slope
Lasers
mentioned above when slope matching
in this way with a FLAT
PLANE Laser you are in manual mode
and the laser will continue to run even if
the unit is disturbed by being bumped, by wind, etc...
