Battery installation (Fig. 2)
This multi-function digital laser level uses two “AAA” batteries (sold separately), to power both the LCD module display and
the Laser dot.
Fig.2
NOTE: Always ensure the on/off button is in OFF position before installing or replacing the batteries.
Open the battery cover, located in the middle of the back of the level (Fig.2).
Insert two new “AAA” alkaline batteries with the polarity (+/-) as indicated on the inside of the battery compartment.
Close the cover securely in place.
Turn on the LCD display
Press the Power button to turn the LCD display screen on. When the screen rst comes on, the temperature is displayed in
centigrade for about 2 seconds, to indicate if level is being used in optimum operating temperature range. The current angle
of the level is then displayed, and a picture of that angle is shown either above or below the line for true level. An arrow on
the display indicates if the level has to be moved up or down. True level is reached when the two lines are together and the
angle shows 0.00°. Turn off the LCD display by pressing and holding the button in for about 2 seconds. If the digital level is
not used for 5 minutes the level automatically turns off. The LCD display is large and easy to read. When the level is turned

Calibration (Figs.3,4)
Place the digital level on a at and smooth surface, push and hold the REF button for about 3 seconds, the calibration
mode is activated. “CAL1” will wink on LCD.
Keep it unmoved for seconds until hear the beeper sounds for 1 second, then “CAL2” will show on LCD.
Rotate the level 180º in the same location then press the REF button, “CAL2” will wink, keep it unmoved for seconds, then
the beeper will sound for 2 seconds to tell calibrating completed, the LCD will show the current angle in high-accuracy-dis-
play.
Fig.3 Fig.4
Important NOTE:
The digital level has been pre-calibrated to high-accuracy-display mode. It possibly runs to rough-accuracy-display
mode if the temperature changes too much. Suggest calibrating the digital level every time before you use it.
To ensure an accurate measurement, the calibration should be performed separately for horizontal measurement,
plumb measurement or upside measurement.
The calibration must be performed on a at and smooth surface with the gradient no more than 5º. If it exceeds 5º, the
beeper will be buzzing for 3 seconds, “Err” will show on the LCD to tell the calibration failed, then exits automatically.
In the calibration, the level also can not be beveled or moved, same Err will occur with the wrong operation.
After CAL1 is nished, the level should be rotated 180 degree to start CAL2, if keep the level not moved and start
CAL2, the digital display will wrongly set the current working surface as 0°, it will recover to normal function after a
correct calibration.
The high accuracy display is only available when the display unit switches to degree or % and the gradient must be
within 1º. If the gradient exceeds 1º, LCD will recover to rough accuracy display.

Measurements
Horizontal and Plumb measurements can use both the bubble vial and the LCD readout features.
Horizontal measurements (Fig.5)
Use the level on horizontal surfaces to true them up. The level’s bubble vials will show when you have the surface level.
The bubbles will be exactly in between the marks on the vial.
Once the Power button is turned on, lay the level on the surface you want to level. The LCD display will show the surface
you are measuring as a line either above or below the true level line, and the degree to which the surface is off, with an
arrow showing whether the surface should be raised or lowered in order to be leveled.
Fig.5
The LCD display also gives the degree to which the surface is off. To level, move the surface with
the level on it until the two lines on the readout match and the readout says 0.00° for the angle. If the
beeper is activated, the beeper will sound when the level is at level.
Vertical measurements (Fig.6)
To nd the plumb of a work surface, lay 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 shows the surface with the level on it as a line, and true plumb as another line either
to the left or right of the line for plumb, and the degree to with the surface is off, with an arrow showing
whether to move the surface to the left or right. If the beeper button is on, the level will beep when true
plumb or 90.00° is reached.

Pitch (Fig.7)
The digital level can be used to measure the pitch of a roof. It measures the pitch in
inches of rise per foot of run. Push the conversion button to change angle to pitch. The
pitch will be read as inches per foot in 1/8-in. increments, with a + or a - sign to indicate
if the pitch is above or below the desired measurement.
Angle (Fig.8)
The digital level measures any angle in degrees with up to 0.1° accuracy, at level or
plumb position, the accuracy will be up to 0.05°. This can be used to nd the necessary
angle for many surfaces, and when the conversion button is pushed to display angle,
will tell you the angle and which way it is off of true level. If the beeper button is turned
on, the level will beep at 0.00° angle.
Slope (Fig.9)
The digital level measures the slope of a surface in percent. This is useful when lay-
ing 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 0.00%. If the beeper
button is turned on, the level will beep at 0.00%.

Laser alignment (Fig.10)
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 50m indoors or outdoors (This range is only
applicable at night or dark environment.)
To activate the laser dot, press in the Laser ON/OFF button located
on the right endcap of the level
The center of the laser beam is 30mm above the bottom (working)
surface of the level.
Remember to account for this when doing layouts and taking mea-
surements.
Level the work surface, and the laser will project the level up to 50m
away to enable you to level large areas.
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.
Operation with tripod (Figs.11,12 and 13)
This level can be used with a tripod to project a beam for up to 50m away. This feature is perfect for home improvement
projects such as aligning pictures, chair rails and other wall xtures, plumbing runs, and many other uses.
Adjust the tripod to true level, using the bubble vial on the base of the tripod.
Screw the level to the tripod using the 1/4-in. threaded hole located in the center of the working surface of the level
(see Fig. 11).
Adjust the height of the laser line you want to project.
Make any nal adjustments to tripod and level to nd the true level point. This will be
at 0.00° on the LCD display screen and, if activated, the beeper will beep.

Current reading memorize button and memory recall
To save the information of the current reading, press the M button. The level can save nine different readings in its memory.
To read out the measurements, press the MR button. The last nine measurements can be read out, beginning with the most
recently saved. To make a new measurement, press the M button to return to measuring mode.
Using conversion button to change display units
The conversion button changes the measurement units from degrees (°) to pitch (in/ft) to slope percent (%). Pitch readings
are in 1/8-in. per foot increments. Plus and minus signs indicate when the pitch is slightly more (+) or less (-) than true
level shown on the display. The conversion button can be used even when the display is in the MR mode. This feature is a
convenient way to convert angles from one unit to another, For example, a 5-in/ft. roof pitch measurement can be converted
to 22.6° for setting up cuts on a chop saw.
Absolute angle and relative angle measurements
Absolute angle measurement
Lay the digital level on a working surface with the base at against the surface.
When level power is turned on, the display indicates the absolute angle between “level” and working surface. The zero line
indicates the level position, and the arrow indicates the direction of the working surface either above or below level.
To activate the beeper, push the beeper button. The beeper will sound when the level is at 0° (level), 45°, 90° (plumb) and
last saved angle. To deactivate beeper, push button a second time.
To save the measured angle in memory, press the M button. This level can remember the last nine measurements. To dis-
play the data in memory, press the memory recall button to recall recorded angles. The level will read out the data starting
with the most recent measurements and going backwards to the earliest in its memory.
To take a new measurement, press the hold button to return to measurement mode.
Relative angle measurement
Lay the digital level on the First working surface.

ProDigit 60

Turn on the level. The LCD screen indicates the absolute angle between true level and the working surface.
Press the REF button to enter relative angle measurement mode. The current angle will be considered to be 0.0° and the
display will read 0.0°.
Place the digital level on the Second working surface and the relative angle between the First working surface and the
Second working surface will be displayed. The zero line indicates the First working surface position, and the arrow indicates
the direction
of the Second working surface either above or below the First working surface level.
At this point you can change the display units for the measured angle from degrees (°) to pitch (inch/foot) or slope (%) by
pressing the conversion button.
