Zero Button
- Absolute/relative
angle conversion
button for comparing
two work
surface angles.
1.
When the level is first turned on, it is in the absolute angle mode and displays
the angle from true level.
2. Take a measurement
of the first work surface; the LCD screen indicates the
angle between that surface and true level.
3.
Press the zero button for the relative angle mode, and the level will set the first
angle to zero.
4.
Move the digital level to the second work surface, and the LCD screen
indicates the relative angle between the first and second surfaces.
5. To return to absolute angle again, turn the power button off and back on.
Convert Button - Converts the angle display on the LCD screen among three
different units.
•
Press the button to proceed through the display units: Degrees (o),Slope (%),
and Pitch (in/ft).
•
Pitch readings are in increments of 1/8-in. per ft. Plus and minus signs indicate
whether the pitch is slightly more (+) or slightly less (-) than the pitch that is
shown on the display..
LASERTRAC
ALIGNMENT
(Fig. 5)
This digital level contains
a laser diode located
inside the left end cap. It
provides
a bright, 635-665
nanometer
beam with a useful visibility
that extends
up to 300-ft.
indoors or outdoors
(This range is only applicable
at night or in a
dark environment).
1. To activate the LaserTrac,
press in the Laser on
Demand Button located
on the right end cap of the
level (Fig. 5).
2. The center of the laser
beam is 1-1/8-inch above
the bottom
(working)
surface
of the level.
Remember
that the laser
Fig.
Laser On Demand Button
point will be 1-1/8 inch higher than the surface on which the laser is sitting.
3.
Level the work surface,
and the laser will project up to 300-feet
away to
enable you to level large areas.
4. The laser projects a round dot on the targeted surface.
The dot size and
shape may change slightly with distance, temperature,
or target-surface
material. The point to reference is the center of the dot pattern.
TO USE THE LEVEL FOR HORIZONTAL
AND PLUMB
MEASUREMENTS
Horizontal and Plumb measurements
can be made with both the bubble vial and
the LCD display features
Horizontal
Use the level on horizontal surfaces
to determine
when they are level. Place the
level against the horizontal surface.
The surface will be at true level when the
bubble is positioned
exactly between the marks on the level vial.
The LCD display represents the surface you are measuring as a line, either above
or below the 0, or true level, line, with an arrow showing whether the surface
should be raised or lowered in order to be level.
The digital display shows the degree to which the
surface is "out of level." If the sound is turned on,
the level will beep when true level, or 0% is reached.
Plumb (Fig. 6)
• To find the plumb of a work surface,
place the
digital level against the vertical surface with the
plumb bubble vial at the top. The surface will be at
true plumb when the bubble is positioned
exactly
between the marks on the vial.
The LCD display will show the actual angle of the
surface.
"Plumb"
is 90°; a beep will sound at 90 °
if the sound function
is turned on.
TO USE THE LEVEL FOR ANGLE
MEASUREMENTS
Fig. 7
Pitch (Fig. 7)
• The digital level can be used to
measure pitch, for example,
the
pitch of a roof.
•
Pitch is measured in inches of
rise per foot of run.
• The pitch will be displayed as
inches (in 1/8-in. increments)
per foot, with a + or a - sign to
indicate that the pitch is slightly above or below the displayed measurement.
Push
the Convert button to change the display to Pitch mode (in/ft).
