4. Unit of measurement selection (°degrees / % / mm/m
IN/FT)
After switching on, the screen always shows the actual slope in
degree. By pressing the MODE button you can change the angles
unit display units from degrees (°) to percent (%), to (mm/m) to
pitch (in/ft). Pitch readings are in 1/8-inch/feet increments.
The
icon indicates the current angle’s position, either up
or down away from the horizontal or vertical position.
5. Angle measurement
If the equipment isn’t in level, it will display a value on the screen.
Short press ZERO button to set current angle to zero, keep the
equipment still after pressing the button for 3 seconds around, the
icon would flash during this period, then it automatically enters
into the relative angle measurement mode. The
icon would
sustaining show on the screen. Short press ZERO button again to
exit the function.
6. Hold
If you need to move the device to read the display, press the HOLD
button to freeze the measurement. The
icon will display. Press

press ON/OFF button, until the LCD display reads “CAL”.
c. Keep the equipment still for a period of time and then press the
HOLD button, display reads “CAL1”.
d. In the same location, rotate the equipment 180°(see the following
figure), then press the HOLD button
, display reads “CAL2”. After
the “CAL2” disappears, the calibration is completed and then the
LCD will show the current angle in high-accuracy-display.
NOTE:
● The calibration must be performed on a flat and smooth surface
with the tilt no more than 5°. If it exceeds 5°, display reads “Err”,
that indicates the user can’t proceed to do the calibration.
● During calibrating, the level also can not be beveled or moved.
● After completed calibration, the equipment automaticall
y replaces
from original factory data to consumer’s data, so it must be careful
to use this function.
