Mode Key
Push the MODE button to switch from one construction language
to another. This controls which construction language your
electronic module will measure in. Your level has the capability to
measure in Degrees, Percentage of slope, Millimeters per Meter, Inches
per Foot (Slope, Pitch) in decimal form and Inches per Foot in fractions of
an inch. A symbol on the upper right of the screen will explain which
MODE you are currently in.
Laser Key
Turn on/off the laser. The instrument will beep once.
Calibration Key
Please refer to Section 8 “Self-Check and Fine Calibration”.
Auto Shut-off
The electronic module will automatically shut-off in 20 minutes if no
key is pressed.

the instrument gets closer to the position of 0º and 90º. When the
CD displays 0º or 90º, there will be a continuous tone sound.
Hold Function
Press the hold key once (unit will beep once) to activate this function
and to display the HO D symbol on the CD. Now the instrument will
hold the current angle reading and the display will flash.
Laser Indication Function
The aser symbol displayed on the CD means that the laser
beam is activated. The laser output window will emit a bright
red laser dot.
Inclination Indication
The triangle arrows displayed on the two ends of the CD indicate
the inclination direction of the laser digital level.

8. Self-Check and Fine Calibration
Checking the Horizontal Calibration
Select a flat and horizontal platform as a reference
surface, like a table-surface.
1. Place the laser digital level on this reference
surface, as shown in figure 1, and then record
the measured angle reading. Record this as A1.
2. Turn the laser digital level 180 degrees, as
shown in figure 2, and then record the
measured angle reading. Record this as A2.
3. If A1-A2 is greater than 0.2º, it is necessary to
calibrate the horizontal accuracy.
Checking the Vertical Calibration
Select a flat and vertical platform as a reference
surface.
1. Place the laser digital level on this reference
surface, as shown in figure 3, and then
record the measured angle reading. Record
this as A1.
2. Turn the laser digital level 180 degrees, as
shown in figure 4, and then record the
measured angle reading. Record this as A2.
3. If A1-A2 is greater than 0.2º, it is necessary
to calibrate the vertical accuracy.
IMPO TANT: It is the responsibility of the user to verify the
calibration of the instrument before each use.

Horizontal Calibration
1. Press and hold the ZERO key for 3-plus seconds, unit will beep once.
When the CD shows -0-, it means the instrument has already
entered the calibration status.
2. Place the laser digital level on the horizontal reference surface, as
shown in figure 5, after 10 seconds, press the ZERO again, and the
CD shows -1-.
3. Turn the laser digital level 180 degrees, as shown in figure 6, and
after 10 seconds, press the ZERO key again, and the CD shows -2-.
Wait for 2 seconds, and the laser digital level will show the angle
reading. The horizontal calibration is now completed.
Vertical Calibration
1. Press and hold the ZERO key for 3-plus seconds,
unit will beep once. When the CD shows -0-, it
means the instrument has already entered the cali-
bration status.
2. Place the laser digital level on the vertical reference
surface, as shown in figure 7, after 10 seconds,
press the ZERO again, and the CD shows -1-.
3. Turn the laser digital level 180 degrees, as shown in
figure 8, and after 10 seconds, press the ZERO key
again, and the CD shows -2-. Wait for 2 seconds, and the laser
digital level will show the angle reading. The vertical calibration is
now completed.
