OPERATION
2. TURN THE DIGITAL ANGLE FINDER ON, OFF, AND REVERSE THE IMAGE
a. Press the ON/OFF button to turn on the Digital Angle Finder. The LCD
screen will rst briey display all of the angle-calculation elements and
then display the relative angle between the folding leg and the base leg.
b. When the device is turned on, briey pressing the button again will ip the
display on the screen.
c. Press the button and hold it for about 3 seconds to turn off the tool.
d. When the Digital Angle Finder is inactive for 5 minutes, it will automatically
turn off to save battery power.
3. TO USE THE DIGITAL ANGLE FINDER BUBBLE VIALS FOR LEVEL AND
PLUMB MEASUREMENTS
NOTE:
Use the highly accurate bubble vials to establish level or plumb surfaces. The LCD
display is for use in making relative-angle measurements only; it is not useful for level
and plumb measurements. The LCD display may be turned off for this function.
Horizontal measurement
Place the Digital Angle Finder on the work surface; the surface will be at true
level when the bubble is positioned exactly between the marks on the vial.
Vertical measurement
Place the Digital Angle Finder against a vertical work surface; the surface will be
at plumb (true vertical) when the bubble is positioned exactly between the marks
on the plumb bubble vial.

OPERATION
4. MEASURING ANGLES (Fig. 3)
a. Press the ON/OFF button to turn
on the tool.
b. Unfold the folding leg from the
base leg (level body).
c. Place each of the two legs at
against one of the surfaces
forming the angle.
d. The interior angle αbetween the
base leg and the folding leg is
measured and shown on the LCD display.
NOTE:
• If the digital display cannot be read easily (e.g., when working overhead),
press the HOLD button to freeze the display, and the indicator “H” will blink
on the LCD display. The value on the display does not change even when the
legs are moved with respect to each other and the tool is moved. Press the
button again to free the display.
• Contact surfaces and contact edges must be clean. Dirt particles may lead to
inaccurate measurements.

5. USING THE LEG EXTENSION (Fig. 4)
The leg extension assists angle
measurement when the geometry of the
surfaces that form the angle are such
that the folding leg cannot contact one of
the surfaces.
a. Attach the leg extension: Slide the
leg extension from the end onto
the folding leg.
b. Extend the leg extension as far
as necessary over the joint of the Digital Angle Finder.
For the measurement, the interior angle α is displayed. (Fig.4) The angle β to be
measured can be calculated as: β = 180°- α.

6. DETERMINING THE MITER AND
BEVEL ANGLES FOR CUTTING
CROWN MOLDING
The Digital Angle Finder can
automatically calculate the exact
miter-angle and bevel-angle cut
settings for precise crown molding cuts,
based on “SPR” and “CNR” information.
Determine, save, and enter the spring
angle (SPR)
a. Tack the crown molding to the
corner of a table with the surface
that will come in contact with the
wall postioned at on the table, as
shown in Fig. 5.
b. Press the power button to turn on
the tool.
c. Place the folding leg at against
the underside of the table, parallel
to the front edge of the table, and
the base leg at against the back
side of the crown molding (Fig. 5);
the supplementary angle of the
spring angle will show on the LCD
display (Fig. 6).
d. Press the “MTR/BVL” button: the
spring angle is automatically
computed and displayed for 3
seconds. “SPR” will also show in
the display (Fig. 7).

e. Press the “SPR” button to save
the SPR angle in the tool for later
use. “S” shown in the LCD display
indicates that the spring angle is
saved successfully (Fig. 8).
NOTE:
• To recall the saved spring angle,
press the SPR button after the tool is
turned on.
• If the spring angle is already known,
follow steps f-h below, to input the
SPR angles.
f. Press the power button to turn on
the tool.
g. Move the folding leg until the
known spring angle is displayed
on the LCD display; press the
MTR/BVL button to input the SPR
angle. “SPR” will show on the LCD
display (Fig. 9 & Fig. 7).
h. Push the “SPR” button to save this value in the tool; the letter “S” shown
on the LCD display indicates the spring angle is saved successfully (Fig. 8).

OPERATION
Determine the corner angle( CNR)
a. After determining or saving the
SPR angle, place one leg of unit
against each of two adjacent walls
to measure the angle of the wall
corner (Fig. 10); “CNR” will blink on
the LCD display.
b. Press the MTR/BVL button to input
the CNR angle, then the “CNR” will
stop blinking. (Fig. 11)
NOTE:
Any time when you turn on the unit,
press the SPR button to check the saved
SPR angle, and then it will go into CNR
mode with CNR blink on LCD display
automatically, place the unit to desired
measuring location as step a. to determine
the CNR angle.
If once you want to use a new SPR angle
instead of the saved SPR angle, place the
unit to desired measuring location, press
the MTR/BVL button, “SPR” will show on the LCD display, this means you are using
current SPR angle showed on LCD, then operate unit follow step a. and b. to determine
the CNR angle.

Determine the miter and bevel angles
for cutting crown molding
a. Press the MTR/BVL button to
display the miter angle; “MTR” will
show in the LCD display (Fig. 12).
b. Press the MTR/BVL button again
to display the bevel angle; “BVL”
will show on LCD display (Fig. 13).
c. Record the MTR/BVL values and
set the miter and bevel angles on
the compound miter saw.
d. To recall the MTR or BVL angles,
press the hold button for 3
seconds go back to the last gure.
e. To return to the normal mode,
press the MTR/BVL button again.
NOTE:
If the angle measured is out of allowable
range of spring or corner angle, “ -----” will
appear in the LCD display and the tool will
revert to the normal measuring mode after approximately 10 seconds. The allowable
range for spring angles is 25.1° to 60.9°; for corner angles it is 59° to 151°.
WARNING
When cutting crown moldings, follow all instructions in the operating manual of
the compound miter saw.
