10" / 24" / 48" DIGITAL LASER LEVEL
OPERATION
NOTE:
• Calibration must be performed on a flat and smooth surface with the gradient no more
than 5º. If it exceeds 5º, the beeper will sound for 3 seconds, and “
Err
” will show on the
LCD display to indicate that the calibration failed, and calibration will stop automatically.
• If, during calibration, the digital laser level is moved, “
Err
” will show on the LCD screen,
with no sound.
• After
CAL2
shows on the LCD, the digital laser level should be rotated 180° to start
CAL2
. If the digital laser level is not moved prior to starting
CAL2
, the digital display will
incorrectly identify the current working surface as 0°. Re-calibrate the digital laser level,
and it will recover to normal function.
4. ABSOLUTE ANGLE MEASUREMENT
Unlike common levels, this digital laser
level allows you to make 360° angle
measurements with superior accuracy.
a. Press the power button to turn
on the digital laser level. Lay the
digital laser level on a working
surface with the base flat against
the surface. The display indicates
the absolute angle between the
working surface and true level.
The zero line indicates the true
level position, and the slope line
indicates the direction of the
working surface either above or below true level.
b. To level the working surface, move the surface with the level on it until the two lines
on the readout match and the readout is 0.00° for the angle.
c. To plumb the working surface, move the surface with the level on it until the two
lines on the readout match and the readout is 90.00° for the angle.
d. Using the bubble vials you can also level or plumb the working surface when the
bubbles are exactly in between the marks on the vial.
NOTE:
If the beeper is activated, the digital level will sound at 0°, 45°, 90° or the most
recently stored value.
