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.

6. Turn on the laser and mark the intersection of the beams as point D.

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.
