To set Squaring:
The FLG-411QG does have a squaring facility to set-out 90 degrees.
Place the instrument on the floor & operate the vertical lines. These will
project along the floor (to set floor squaring), up the walls opposite & square
on the ceiling above too.
The body of the laser can be slowly rotated by hand, keeping the feet in the
same position. This gives a coarse setting on any plumb (vertical) lines.
The User can adjust the fine setting, cross spindle to finalise line positions.
To set Plumb:
Again, switch on all the vertical lines. The Green Cross on the ceiling is true
plumb with the red DOT below the instrument. This is an electronic equivalent
of a plumb string line - a very convenient & useful feature.
To Switch OFF:
Simply turn the transit latch to
OFF / LOCK.
When moving the laser, always select the LOCKED position.
