HORIZON Laser System
System Description
The HORIZON laser system is a one-man leveling tool that allows one
person to take accurate, self-leveled elevation measurements up to 800
feet (250 m) away from the transmitter.
The laser signal is rotated in a 360° plane. The handheld or rod
mounted laser detector reads the laser signal. The detector indicates
the elevation information via a visual display on front and rear LCD's
and also with audible tones. Please refer to the detector operating
manual for details.
The HORIZON laser system is designed for all general construction
and agricultural leveling tasks. Set the transmitter in a central location to
provide an unobstructed continuous elevation reference. This reference
can be used by multiple persons for a variety of leveling applica tions
with additional laser detectors.

How to Use the Laser System
Installing / Removing the Batteries
1. Turn battery housing screws counterclockwise and remove the
battery housing. A universal key (supplied) or small coin can be used
to turn the screws.
2. Install or remove the batteries as required.
Note: When installing the batteries, be sure to note the positive (+) and
negative (–) diagram inside the housing. Place ribbon straps behind
the batteries for easy battery removal.
Note: The laser has reverse-polarity protection. If the batteries are put
in wrong, no damage occurs to the laser, but it does not operate.
3. Put the battery housing in place and turn the screws clockwise to tighten.
Setting Up and Leveling the Laser
1. Set up a tripod to the height appropriate for your application needs.
2. Insert the 5/8-11 tripod screw into the laser’s 5/8-11 threaded insert.
3. Turn the screw and tighten to hold the laser securely in place.
4. Press the power switch to turn the laser on.
Note: When the laser is initially turned on, the out-of-level LED will
flash if the laser needs leveling.
5. Using the left-thumb rule (seethe Note that follows),
turn both X axis screws equal amounts in opposite
directions to move the level bubble to the center of
the bull’s-eye.
Note: Left-thumb rule - both thumbs in, both thumbs
out, the bubble follows the direction of the left thumb.
6. Observe the location of the bubble (top or bottom of
the bull's-eye) and using the left-thumb rule, turn the
Y axis screw to move the level bubble to the center of
the bull's-eye.
Note: When the laser is level, the bubble is centered in
the bull’s-eye and the out-of-level LED stops flashing and the laser’s
rotor begins rotating.
Note: If the laser is knocked out of its self-leveling range, the out-of-level
LED start flashing, the rotor stops, and the laser beam turns off.
7. To restore level, simply re-level the laser and check your initial
reference elevation.

Setting Up and Leveling the Laser
Determining the Height of Instrument (HI)
The height of instrument (HI) is the elevation of the laser’s beam. The
HI is determined by adding the grade-rod reading to a benchmark or
known elevation.
1. Set up and level the laser.
2. Attach the detector to a grade
rod and turn on the detector.
3. Place the grade rod on a
benchmark (BM) or other known
elevation.
4. Slide the detector up or down
the grade rod until the LCD shows
an on-grade reading.
5. Add the grade-rod reading to
the benchmark to determine the height of instrument.
Example: Benchmark elevation = 100.23 ft (30.55 m)
On-grade rod reading = + 4.34 ft (1.32 m)
Height of instrument = 104.57 ft (31.87 m)
6. Use this HI as a reference for all other elevations.

Checking Calibration
To check the horizontal calibration, a tripod with a 5/8-11 threaded
mount, handheld detector, universal key (supplied), or a 1/16 in. (1.5
mm) diameter pin or small nail are required. Having another person to
help saves time if you need to adjust the calibration.
1. Set up and level the laser 100 ft (30 m)
from a wall.
2. Point the Y- axis toward the wall. Raise/
lower the detector until you get an on-grade
reading. Using the on-grade marking notch
as a reference, make a mark on the wall.
This mark is Y1.
Note: For increased precision, use the
fine accuracy (deadband) setting on the
detector.
3. Rotate the laser 180° (Y+ axis toward
the wall) and re-level the laser.
4. Raise/lower the detector until you get
an on-grade reading for the Y+ axis.
Using the on-grade marking notch as a
reference, make a mark on the wall. This
mark is Y2.
5. Measure the difference between the two
marks. If they differ more than 1/8 inch at
100 feet (3.0 mm at 30 m), the laser needs
calibrating.
6. To correct for a calibration error, position
the receiver at the midpoint of the two
elevation marks on the wall. This position
is Y3.
Note: Although you can calibrate the laser
by yourself, having another person to help
saves time.
7. To adjust the calibration, insert the
universal key (or a nail 1/16 in. or 1.5 mm
diameter) into the opening in the calibration
screw and turn the screw in the appropriate
direction.
Note: The arrows on the display show
which direction the calibration screws
need turning. An up arrow on the receiver
indicates that the Y axis calibration screw
needs to be turned clockwise to lower the
laser plane. A down arrow on the receiver
indicates that the Y axis calibration screw
needs to be turned counterclockwise to
raise the laser plane.
8. Rotate the laser 180° back to the original
face. Make sure this axis is less than 1/16
in. (1.5 mm) from the midpoint line.
Note: If additional adjustment is required,
repeat steps 2-7 above.
9. After adjusting the Y axis, rotate the
laser 90°. Repeat steps 2-8 starting with
the –X axis facing the wall.
