24-inch LEVEL
OPERATION cont.
LASER TRAC™ ALIGNMENT (Fig. 9)
This digital level contains a laser diode located inside the left endcap of the level.
It provides a bright 635-665 nanometer beam with a useful visibility that extends up to
300-ft. indoors or outdoors.

laser will project the level 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 use is the center of the dot pattern.

SLOPE (Fig. 8)
The digital laser level measures the slope of a surface in percent. This is useful when
laying pipe for proper drainage. When the conversion button is in the slope mode,
it will display the surface being measured in percent, with exact level at 0.0%.
If the beeper button is turned on, the level will beep at 0.0%.

DESCRIPTION cont.
Up/Down Indicator - The zero line (0°) indicates the level position.
The arrow indicates the current angle's position, either up or down away
from the level (0°).
Battery Power Icon - Indicates the amount of battery power in the unit.
Replace batteries when the black power bar disappears.
Sound / Beeper Icon - This icon appears on the screen when the
beeper function is activated.
Memory Icon - This icon shows when the memory function is being
