Leveling Accuracy; Influences On Accuracy - Skil 8601-RL Instrucciones De Funcionamiento

Influences on Accuracy

The ambient temperature has the
greatest influence. Especially
temperature differences occurring
from the ground upward can divert
the laser beam.
As thermal fluctuation is largest
close to the ground, the tool, if
possible, should be mounted on a
commercially available tripod and
placed in the center of the working
area. Apart from exterior
influences, device specific
influences (such as heavy impact
or drop) can lead to deviations.
Therefore, check the accuracy of
the tool each time before starting
your work.
Should the tool exceed the
maximum deviation during one of
the tests, see recalibration
procedure or have it recalibrated
by a Skil after-sales service center.
Leveling
Level the laser tool using leveling
wheels and bubble vials.

Calibration
Although the laser tools are
calibrated to specification before
leaving the factory, they contain
many precision-machined parts
that may be affected if subject to
abuse. Therefore, if a unit is
dropped or sustains significant
impact, check its calibration. It is
also recommended that the tool
be periodically calibrated, as a
normal maintenance procedure.
To Calibrate the Laser:
1. Select a site for calibration that
allows the unit to be placed
about 50 ft. (15m) away from a
smooth vertical surface, such
as a wall.
2. Set the unit on a level surface
at one end of the range.
3. Position the unit so that the
front of the instrument is
perpendicular to the target.
4. Using the leveling wheels,
center both horizontal vials,
paying particular attention
to the vial perpendicular with
your target.
Note: Allow 5-10 seconds for the
bubble to settle before reading the
bubble vial and adjust as needed.
5. Without disturbing the laser
unit, point the beam to the
target until the beam hits your
target (vertical surface).
