LCD DISPLAY AND BUTTON FUNCTIONS
LCD screen icons
Up/Down Indicator:
•
The zero line (0º) indicates the “true level.”
•
The second line, appearing either above or below the 0° line, indicates the
level’s position relative to “true level.”
•
The arrow indicates the direction in which the level needs to be moved to
achieve “true level.”

attery Power Icon - Indicates the amount of battery power in the unit.
B
Replace batteries when the black power bar disappears.
Sound Icon - This icon appears on the screen when the sound function is
activated.
Hold Icon: Indicates that the displayed measurement is frozen.
Button Functions
Button (On/Off, Sound)
Press the button to turn the LCD display screen on.
•
When the LCD screen first comes on, the ambient temperature is displayed
in Fahrenheit for approximately 2 seconds to help the user determine whether
the level is being used in the optimum temperature range (32º to 104º F).
•
The current angle of the
level is then displayed on
the LCD screen, and a line
representing that angle
is shown either above
or below the line that
indicates the position of
true level (Fig. 3).
•
Briefly press the button
once more to activate the
sound, which will beep when the level is positioned at 0°, 45°, 90°, and last
hold angle to true level.
•
Briefly press the button a third time to turn off the sound. Additional brief
presses on the button will turn the sound function on and off.
•
An arrow on the display indicates the direction in which the level needs to be
moved to reach true level.
•
True level is indicated
when the angle line and
the level line in the display
are together, and the
angle shows 0 (Fig. 4).
•
Turn off the level by
pressing the button
and holding it in for
approximately 3 seconds.
•
The level will shut itself off when it has not been used for 5 minutes.

Zero Button - Absolute/relative angle conversion button for comparison of two
work surface angles.
1. W
hen the level is first turned on, it is in the absolute angle mode and
displays the angle from true level.
2. T
ake a measurement of the first work surface; the LCD screen indicates the
angle between that surface and true level.
3. P
ress the zero button for the relative angle mode, and the level will set the
first angle to zero.
4. M
ove 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 3
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.
Hold Button
To hold the information of the current reading, press the Hold button to freeze
the displayed reading; press it again to return to measuring mode.
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
is on, the level will beep when true level, or 0°, is reached.

PLUMB (Fig. 5)
Fig. 5
•
T
o 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.
•
T
he LCD display will show the actual angle of
the surface. 90° is “plumb;” a beep will sound
at 90°, if the sound function is turned on.
TO USE THE LEVEL FOR ANGLE MEASUREMENTS
Pitch (Fig. 6)
•
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 read
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.
Fig. 6
Push the convert button to
change the display to Pitch
mode (in/ft).
Angle (Fig. 7)
Fig. 7
The digital level measures any
angle in degrees, with up to
0.1° accuracy. If the sound
button is turned on, the level
will beep at the 0°, 45°, 90°,
and last hold angle.
Push the convert button to
change the display to Angle
mode ( º).
Fig. 8
Slope (Fig. 8)
The digital level measures the
percent slope of a surface.
This is useful when laying pipe
for proper drainage. When the
display is in the slope mode,
it will measure the surface in
percent, with exact level a
48295 Manual_Revised_07-0620
Page 8
0.0%. If the sound is turned on, the level will beep at 0.0% and 100%.
Push the convert button to change the display to Slope mode (%).
ABSOLUTE AND RELATIVE ANGLE MEASUREMENTS
Absolute angle measurement
1. Place the digital level on a working surface with the base flat against the surface.
2. T
he display indicates the absolute angle between “true level” and the working
surface. The zero line indicates the level position, and the arrow indicates the
orientation of the working surface: either above or below true level.
3. T
button. The level will beep
o activate the sound, briefly press the
when the level is at 0° (level), 45°, 90° (plumb), and last hold angle.
4. P
ress the Hold button to freeze the display reading. To take a new
measurement, press the hold button again to return to measurement mode.
Relative angle measurement
The relative angle mode allows you to measure the angle of difference between
2 different surfaces.
1. Place the digital level on Surface 1.
2. The LCD screen indicates the absolute angle between true level and Surface 1.
3. P
ress the ZERO button to activate the relative-angle measurement mode.
The current angle will be considered to be 0.0° and the display will read 0.0°.
4 P
lace the digital level on Surface 2, and the relative angle between Surface
1 and Surface 2 will be displayed. The zero line indicates the Surface 1
position, and the arrow indicates the orientation of Surface 2, either above or
below Surface 1.
5. A
t this point you can change the display units for the measured angle from
degrees (°), to pitch (inch/foot), or slope (%) by pressing the convert button.

MAINTENANCE
This digital level has been designed to be a low-maintenance tool. However, in
order to maintain its performance, follow these steps:
1. H
ANDLE the tool with care. Treat it as a precision optical device, such as a
camera or binoculars.

VOID exposing the tool to shock, continuous vibration, or extreme hot or
cold temperatures.
3. S
TORE the tool indoors and in a safe place.
4. T
he Level is designed to be weather resistant and construction-site tough. If
the level is splashed with mortar or other construction-site residue, simply
wipe it clean with a damp cloth.
5. D
O NOT immerse the level in water.
6. Aluminum surfaces can be cleaned with a non-abrasive powder.
7. R
EMOVE the batteries from the tool if it is not going to be used for an
extended period.
8. D
O NOT attempt to take the level apart.
