The Klein Tools 935DAA measures angles from true level. It can also be
set by the user to notify when a desired angle is reached. The magnetic
base attaches to pipes, table saws, and other ferromagnetic surfaces. The
V-grooves easily align to the axes of conduit and pipes.

return to measuring true level, press the Power/ZERO Button
2
.
HOLD: To hold a measurement value on the display, press the ANGLE
TARGET DECREASE / HOLD Button
8
. When the hold function is active,
the hold icon

. When measuring from 0-90°, the 90° Range Setting icon
F
will be shown on the display. When measuring from 0-180°, the 180° Range
Setting icon

INCLINATION: The Inclination Icons
H
indicates the direction the 935DAA
must rotate in order to measure either 0° or 90°:
• In FIG. B, the 935DAA on the left must rotate clockwise in order to reach
0°; the 935DAA on the right must rotate counter clockwise to in order to
reach 0°.
• In FIG. C, the 935DAA on the left must rotate clockwise to in order to
reach 90°; the 935DAA on the right must rotate counter clockwise in
order to reach 90°.
• In FIG. D, When no inclination icons are shown, the measurement value
is 0° or 90°.
ERROR: " " will be displayed when the device is tilted 30° backward
or forward (FIG. E). At these angles, the 935DAA is not able to provide
accurate measurements.

3. Wait until the LEDs turn on.
Now the user is in Angle Alert mode.
LEDs will show red when beyond 5° of the target angle and beep slowly.
LEDs will show flashing orange when within .2° to 5° of the target angle and
beep quickly.
LEDs will show green at 0°, and at the target angle within +/- 0.2° and will
continuously beep.
• In FIG. F, an example of the three different LED states is shown when the
target angle is 45°.
To change the target angle when in Angle Alert mode, the user can either:
• Press the Angle Alert button to cycle through the presets again.
