Product Manual

8. Accurately measure the elevation to the center of the beam at point B and record the elevation

as B1.

9. Move the pipe laser behind point B and aim the laser beam so that it passes over points A and B.

Allow the pipe laser to self-level.

10. Accurately measure the elevation to the center of the beam at point B and record the elevation

as B2.

11. Accurately measure the elevation to the center of the beam at point A and record the elevation

as A2.

12. Subtract the A1 and B1 elevation readings from A2 and B2 elevation readings.

Note: Your laser is in calibration if the difference between A2 – A1 equals B2 – B1.

Note: If A2 – A1 is greater than B2 – B1, the laser beam is shooting high and you should readjust the

laser’s calibration bringing the beam to level.

Note: If A2 – A1 is less than B2 – B1, the laser beam is shooting low and you should readjust the

laser’s calibration bringing the beam to level.

Note: If the error is greater than 0.02 feet in 100 feet (6.4 mm/30 m), return the pipe laser to an

authorized Trimble service center.
