INSTRUCCIONES DE FUNCIONAMIENTO
The SitePro hand level is a carefully
made precision instrument, designed
to be easy to use. It has a level
vial and center mark which, when
properly aligned, establishes a true
level line of sight. This is the same
principle of operation used in surveying
instruments.
Hold the hand level with either hand,
being careful not to cover the level
vial opening located at the top of the
level. The sensitive level vial, center
mark, and the object on which you are
sighting can all be seen through the
level at the same time.
To obtain a true level line of sight,
sight through the eyepiece and raise
or lower the end of the level opposite
the eyepiece until the vial bubble
intersects the center mark. This
establishes a level line of sight which
is a continuous, perfectly straight line
for as far as you can see. All points or
objects along this line are exactly level
with the hand level and your eye.

All measurements are taken from this
level line of sight to establish levels,
slopes and grades.
You can quickly and easily check
the level of retaining walls, fences,
masonry, batterboards, foundations,
etc. by simply sighting on the object
and noting its position in relation to the
level line of sight as seen through the
level. To establish difference in level,
an assistant should be used to help
you obtain necessary measurements.
For even more accurate reading
over large distances, the hand Level
may be steadied against a board or
measuring rod, or rested on any solid
level object.
DIFFERENCES IN ELEVATION
Have the assistant hold a measuring
rod, folding rule or straight stick in
various locations. Sight through
level with vial bubble centered, and
have assistant note or mark the
measurements on the rod.
