Digital Leveling
NOTE: Use the Angle Base as the standard testing base which will
be adhered on the working surface while measuring in this mode.
Only the measurements underneath this are considered to be
accurate.
Absolute Angle Measurement
Unlike common levels, this tool
Fig. 12
makes 0-90° angle measure-
ments with superior accuracy.
Press the UP Arrow Button or the
Down Arrow Button to change
the mode to digital leveling. The
LCD will display "Level" on the
lower right (FIG. 12).
1. Place the tool's Angle Base on
the surface to be measured. The
display indicates the difference,
in degrees, between that surface and absolute level.
2. To level the working surface, move the surface with the tool
on it until the readout is 0.0°, which indicates "level".
3. To plumb the working surface, move the surface with the tool
on it until the readout is 90.0°.
NOTE:
The tool will only beep at 0°, 45° and 90°, with ±1°ac-
curacy. When deviation (positive or negative) is from 0.1 to 0.5
degree of one of the three angles, the tool will beep at a higher
frequently; from 0.6 to 1.0 degree of one of the three angles, the
tool will beep at a less frequently.
