The inclination of laser plane
NL810 allows you to incline the laser plane in one or two directions
Press 4 button which will go into a mode of enter the inclinations
Press 3 to enable selection of the axis along which surface will be tilted (X
or Y).
To set the inclination in the X-axis, press the buttons 7, respectively (positive values) or 8
(negative values) - every time pressing the laser beam will tilt to the surface - in the X or Y
plane, on the top cover of the laser are marked directions of inclinations. Positive values will
incline laser plane according to the arrow on the top cover, negative - in the opposite direction)
After entering the inclination value for the X-axis, Y-axis, press 3 again after approx. 3 seconds,
the plane begins to be tilted to entered values.
Press the 4 button to exit set inclination mode, the plane will be automatically leveled.
1. Establish a target line parallel to desired direction of grade.
2. Set up the laser over this line (drop a plumb bob from the tripod mounting screw).
3. Rough align the instrument to the direction of grade.
4. Place a rod or other target down range on the target line.
5. While sighting through the collimator, adjust the instrument until the sight is aligned with the
target.
PRINCIPLE OF OPERATION
Height Measurement
Turn the power on to Level the instrument itself. Once leveled, the laser
head starts to spin, setting the laser plane. Attach the laser sensor on the
laser staff. Place a laser staff with attached sensor on a benchmark (zero
point)- reset the position of sensor (adjust the height of the sensor to define
a zero level, the laser staff should also indicate zero). Move the laser staff
with sensor to another point which height you want to measure, adjust the
height of the sensor to place it in the field of the laser beam - move it up or
down on the laser staff. The difference of sensor positions on the staff will
