8. Self-Check & Fine Calibration
IMPORTANT: It is the responsibility of the user to verify the
calibration of the instrument before each use.
1. Set the instrument on a level flat head tripod centered
between two walls (marked 1 & 2) approximately 15 feet
apart. (See fig. 1).
2. Point the instrument directly at wall 1. Turn the laser on and
mark the intersection of the beams as point A.
3. Turn the instrument 180 degrees so that the laser is pointed
directly at wall 2. Turn the laser and mark the intersection of
the beams as point B.
4. Move the instrument and the tripod so the laser is positioned
approximately 2 feet away from wall 1 (see fig. 2). Level the tripod and position the instrument on the tripod facing wall 1. Turn
the laser on and mark the intersection of the beams as point C.
5. Turn the laser off and rotate the laser 180 degrees so that it is
facing directly to wall 2.
Wall 2
Wall 1
6. Turn on the laser and mark the
intersection of the beams as point D.
Fig 1
7. Measure the distance between
points A & C.
8. Measure the distance between
points B & D.
9. If the difference between points
A & C and points B & D are less
than 1/16”, your instrument is within
its tolerance.

Calibration
Re-calibration can be performed as described below.
1. Use a level to mark a horizontal reference line on the wall.
2. Power on the unit to compare the projected horizontal line with
its references. Compensator has to be locked before
making calibration adjustments. If it tilts, remove the side
plastic screw/plug and use an allen wrench to calibrate the
unit through its side calibration hole. Rotate the allen
wrench clockwise when the horizontal line tilts right. Rotate
the allen wrench counter-clockwise when the horizontal line
tilts to the left.
3. If the horizontal line is too low or too high, carefully
disassemble the window frame by removing the outer plastic
screw/plug and the inner metal screw. Use an allen wrench
to calibrate the adjustment screws located between the
glass prisms. Rotate the allen wrench clockwise when the
horizontal line is too low. Rotate the allen wrench counterclockwise when the horizontal line is too high. Reassemble
the window frame after completing the calibration.
