Accuracy Check
Vertical and horizontal line
Checking the accuracy of the horizontal line
Place the lock switch in the "Unlocked" position.
Position the instrument approx. 5 m away from the
wall. Direct the instrument at the wall and switch
on. Activate the laser line and mark the inter-
section point of laser crosshairs on the wall. Swivel
the instrument to the right and then to the left.
Observe the vertical deviation of the horizontal line
from the marking. If the difference does not
exceed 3 mm, then the Leica Lino L4P1 is within
tolerance.
Checking the accuracy of the vertical line
Place the lock switch in the "Unlocked" position. As
a reference, use a plumb-bob and attach it as
close as possible to an approx. 3 m high wall. Pos-
ition the instrument at a distance of approx. 1.5 m
from the wall at an elevation of approx. 1.5 m. Dir-
ect the instrument at the wall and switch on.
Rotate the instrument and align it with the bottom
of the plumb line. Now read off the maximum devi-
ation of the laser line from the top of the plumb
line. If the difference does not exceed 3 mm, then
the Leica Lino L4P1 is within tolerance.
Vertical plumb points
Checking the accuracy of the upper plumb
point:
Set up the laser on its tripod o wall mount bracket
near point A1 at a minimum distance of 1.5 m from
point B1. The horizontal laser is aligned in dir-
ection 1. Mark the laser points A1 and B1 with a
pin.
Checking the accuracy of the lower plumb
point:
