1. When detecting a horizontal laser signal, it is
important to have the bubble vial centered, as the
deflection of the receiver will influence its receiving
accuracy.
2. When detecting a vertical laser signal, it is
important to have the bubble vial centered, as the
deflection of the receiver will influence its receiving
accuracy.
3. Keep the reception window facing the laser while detecting.
4. Hold the unit stable while detecting.

dirty, use a cloth to wipe it clean.
IMPORTANT: It is the responsibility of the user to verify the
calibration of the instrument before each use.
30’
X-Direction Accuracy Self-Check
1. Place the unit on a platform that is 30 feet away from a wall, with
the battery case facing towards the wall. Turn the locking knob to
“ON”, power on the unit in the high-speed rotating status.
2. Draw a vertical line on the wall, and mark the intersection
between the laser line and the vertical line as point A. Note
this test should be done indoors with dim lighting. Its critical
that the laser beam is easily seen.
3. Turn the instrument 180 degrees, mark point B on the wall at the
intersection of the laser beam and vertical line. Also mark the center
between point A and point B as point O.
4. Measure the vertical distance (h) between point A and point B.
5. If h≤0.118", accuracy is within specification. If not, the accuracy
is beyond the specification. If beyond the specification, the unit
can be calibrated as follows.
2. Remove the rubber plug from the X-direction self-calibration
aperture inside the battery compartment. Adjust the weight
screw inside the instrument core
with a flathead screwdriver.
3. If point A is above point O, rotate
the screwdriver counterclockwise. If point A is under the point
O, rotate the screwdriver clockwise. (Rotating the screwdriver 1
rotation will adjust the laser line 1mm).
4. Check the accuracy again following the X direction accuracy
self-check. If the accuracy is still beyond specification, readjust the weight screw again until the accuracy is correct.
Y-Direction Accuracy Self-Check
1. Rotate the instrument 90 degrees and place it on the platform.
2. Check the accuracy of Y-direction with the same method as
that of X-direction (mark the point as C and D).
3. If the accuracy is beyond specification the unit can be
calibrated as follows.
2. Screw off the Y-direction self-calibration aperture bolt located
behind the handle. Adjust the weight screw inside the instrument core with a flathead screwdriver.
3. If point C is above the point O, rotate the screwdriver counterclockwise. If point C is under the
point O, rotate the screwdriver clockwise.
Note: After the unit is checked in one direction, check
the other direction, until the accuracy of the two directions are both
within specification.
Note: Install the self-calibration aperture screw and rubber stopper
after finishing the accuracy self-check and calibration.

“H1” between the laser rotating plane and the platform surface.
2. Set the locking knob to “OFF” position, and place the instrument
in vertical position.
3. Rotate the vertical adjusting knob to center the bubble.
4. Measure the distance “H2” between the top laser beam and
the platform surface.
5. Mark E in the position that is equal to (H1-H2) under the point O.
6. Adjust the adjusting knob to make the laser beam aim at E.
7. Check the bubble to see if it is centered. If it is not yet instrument will need to be sent in for calibration.
