Check & Adjust
FlexLine, 247
1. Set up the instrument on the tripod approximately 1.5 m above the ground and
level up.
2. To activate the laser plummet, turn on the instrument, and, if tilt correction is set
to 1- or 2-axis, the laser plummet will be activated automatically, and the
Level/Plummet
screen appears. Otherwise, press
FNC
from within any
application and select
Level/Plummet
.
3. Mark the center of the red laser dot on the ground.
4. Turn the instrument slowly through 360°, carefully observing the movement of
the red laser dot.
5. If the center of the laser dot makes a clearly circular movement, or moves more
than 3 mm away from the point which was first marked, an adjustment may be
required. Call your nearest Leica service department.
Depending on brightness and surface type, the size of the laser dot can vary. At
a height of 1.5 m an average diameter of 2.5 mm is estimated.
Inspection of the laser plummet should be carried out on a bright,
smooth and horizontal surface, such as a sheet of paper.
The maximum diameter of the circular movement described by the
center of the laser dot should not exceed 3 mm at a height of 1.5 m.
