Basic Functions
QUADRANT: This indicates which quadrant the
blade of the digital angle finder is in.
ON /OFF: Turns the digital display ON and OFF.
The digital display will automatically shut off in 5
minutes after non-use.
HOLD: Freezes the digital display.

DIGITAL ANGLE FINDER
INSTRUCTIONS
Figure 1. Model H8258.
ZERO/ABS: When pressed and released, toggles
the digital display back-and-forth between the
"ABS" (absolute) mode and zeros the incremental
display.
Press and hold the ZERO/ABS button for more
than five seconds will set a new zero point, mak-
ing the current blade location zero, ABS.
Using the Incremental Display
Being able to zero the display is useful when setting up machinery, because you can use any angle
as a starting point to indicate how much you've
moved a component during adjustments without
adding/subtracting angles from each other.
Example—If you need to drill holes at 15° with
your drill press: 1) Set the blade to 90˚ and place
it on the drill press table, 2) press the ZERO/ABS
button, 3) rotate the blade until the digital display
reads 15°, and 4) rotate the table until the drill
press spindle is parallel with the blade of the digital angle finder.

The digital angle finder can be easily calibrated
by setting it on a flat surface with the blade
positioned parallel to the beam. Press and hold
the ABS/ZERO button while the display is in the
"ABS" mode. After performing this operation, the
display will show numbers getting larger when the
blade is rotated clockwise.
Orientation
When the blade is rotated counterclockwise past
zero, the numbers will display upside down while
the display is in the ABS mode. Switching to the
incremental mode will cause the display to read
right-side-up regardless of the direction the blade
is rotated.
Angle Range Selection
The digital angle finder can be set to 4 different
ranges of angle. The label on the blade is represented in Figure 3. The label assumes the digital
angle finder has been calibrated as described
above. Here is a brief explanation of what the
label means:
Figure 3. Each circle represents a location the
lock knob can be installed.
Battery Change
Battery Type Required ......................... CR2032
To change the battery, rotate the round cover on
the back of the digital angle finder counterclockwise. Pry the battery out and replace it, as shown
in Figure 4.
Note: Removing the battery resets the calibration
of the digital display. Re-calibration is required for
accurate results.
0˚~ 2 2 5 ˚ When the lock knob is secured in this
position, the range of motion for the blade will be
from 0˚ with the blade parallel to the beam and
greater than 225˚ when the blade is rotated clock-
wise to the extreme.
-45˚~180˚ When the lock knob is secured in this
position, the range of motion for the blade will be
from -45˚ to 180˚. This means the blade can be
rotated counterclockwise to -45˚ and clockwise to
18 0˚.
-180˚~45˚ When the lock knob is secured in this
position, the range of motion for the blade will be
from -180˚ to 45˚. This means the blade can be
rotated counterclockwise to -180˚ and clockwise
to 45˚.
-225˚~0˚ When the lock knob is secured in this
position, the range of motion for the blade will be
from -225˚ to 0˚. This means the blade can be
rotated counterclockwise to -225˚ and clockwise
to 0˚.

Note: Rotate the blade to one extreme or the
other before removing the lock knob.
