Accuracy Check
Vertical and horizontal line
Checking the accuracy of the horizontal line
Place the lock switch in the "Unlocked" position
(see
). Position the instrument
approx. 5 m away from the wall. Direct the instru-
ment at the wall and switch on. Activate the laser
line and mark the intersection 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
instrument is within tolerance.
Checking the accuracy of the vertical line
Place the lock switch in the "Unlocked" position
(see
). As a reference, use a plumb-
bob and attach it as close as possible to an
approx. 3 m high wall. Position the instrument at
a distance of approx. 1.5 m from the wall at an
elevation of approx. 1.5 m. Direct 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 deviation of the laser line
from the top of the plumb line. If the difference
does not exceed 2 mm, then the instrument is
within tolerance.
Should your instrument be outside of the
specified tolerance, please contact a local
dealer or an authorised Leica Geosystems
distributor.
Vertical plumb points
Checking the accuracy of the upper plumb
point:
Place the lock switch in the "Unlocked" position
(see
). Set up the laser on its tripod
to wall mount bracket near point A1 at a minimum
distance of 1.5 m from point B1. The horizontal
laser is aligned in direction 1. Mark the laser
points A1 and B1 with a pin.
Checking the accuracy of the lower plumb
point:
