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.
