OPERATION
NOTE:
• If not used for 5 minutes the digital laser level automatically turns off.
• The LCD display is large and easy to read. When the digital laser level is turned upside
down, the LCD screen senses this and changes to read correctly in the inverted position.
3. CALIBRATE THE DIGITAL LASER LEVEL
NOTE: The digital laser level has been pre-calibrated to operate in high-accuracy-display
mode. The high accuracy display (the digital reading displays two decimal places) is only
available when the unit is set to degree or % and the gradient is within 1º. If the gradient
exceeds 1º, the LCD display will revert to regular accuracy display (the digital reading
displays one decimal place). Significant temperature changes can cause the digital laser
level to revert to regular accuracy display. We suggest calibrating the digital laser level
every time before you use it.
To ensure an accurate measurement, the calibration should be performed separately for
horizontal measurement and plumb (vertical) measurement.
a. Place the digital laser level on a flat and smooth surface. Press and hold the REF
button for about 3 seconds. The calibration mode is activated. "CAL1" will blink on
the LCD display.
b. Keep the level motionless for a few seconds, until the beeper sounds for 1 second,
then "CAL2" will show on the LCD screen.
c. Rotate the digital level 180º in the same location. Press the REF button. "CAL2" will
blink on the LCD display.
d. Keep the level motionless for a few seconds, until the beeper sounds for 2 seconds
to indicate that calibration is complete. The LCD display will show the current angle
in the LCD display.
