Second step is to verify the PLUMP (Vertical) laser beam calibration
An 8 ft clear floor space is required for this procedure.
A door jamb is ideal for this leg of the procedures. It eliminates the requirement
of accessing the ceiling for calibration verification, and the use of a ladder.
However, if a ladder is to be used, please refer to the ladder manufacturer's
instructions for its use, safety and precautions. When using door jamb for this leg
of the operation, identify a plump spot on the floor and mark it with a painter's
tape for future reference.
1.
Place the Laser Level on the floor and push the Power Buttom
(Pendulum stays in LOCKED position for now). Make sure to see a solid
laser line on the floor. If the floor surface is reflective, laser beam may not
easily be seen. In this case, adhere a 6 ft long painter's blue tape on
the floor, in front of the beam.
2.
Slide the Pendulum Switch
the beam to stabilize. Use a marker and draw a 1 in long line in the center
of the beam in front of the tool.
3.
Walk to the other side and draw a 1 in long line at the center of the laser
beam at the other end of the tape.
4.
Cut a 2 in long strip of painter's blue tape. Draw a solid 1 in long line at the
center of the tape strip. Place this tape strip over the laser beam on top of
the door jamb or the ceiling. The drawn line should coincide with the center
of the laser beam.
5.
Slide the Pendulum Switch
