Using Your AccuMASTER
Level and Plumb Measurements
Level (horizontal) and Plumb (vertical) measurements can be made with both the LED display
and the bubble vials. The LED display will show the actual angle of the surface with an arrow
showing whether the surface should be moved “in” or “out”. A beep will sound at 0° and 90°, if the
sound function is turned on.
To Use the Level for Angle Measurements
Pitch
The digital level can be used to measure pitch. For example, the pitch of a roof, measured in
inches of rise per foot of run. Push the
button to change the display to Pitch mode (IN/FT).
Slope
When the display is in the slope mode, it will measure the angle or slope of the work surface
in percent, with exact level at 0.0%. If the sound is turned on, the level will beep at 0.0% and
100%. Push the button to change the display to Slope mode (%).
True Level/Relative Angle Measurements
(Alternate Zero Button
)
True Level ―
Place the
AccuMASTER
on a working surface with the base flat against the
surface. The display indicates the absolute angle between “true level” and the working surface.
The arrow indicates the orientation of the working surface: either above or below true level.
Relative Angle Measurements ―
Use this function to compare the angle between two
work surfaces. Press the
button to set the first surface to 0° as a reference. The Alternate
Zero icon
will appear in the lower left of the display. Move the digital level to the second work
surface and the display will show the relative angle between the first and second surfaces.
Press the button again to return to True Level mode.
Calibration
Note:
The device is calibrated in the factory for maximum accuracy. User can re-calibrate if
necessary. It is recommended when you first receive your
AccuMASTER
Level, you should
follow these steps to calibrate it for your local area.

Release when the display flashes
‘CAL1’
and alert sounds.
2. Place the device on a flat, clean surface and press the
button once. The countdown
screen will begin. Wait until countdown reaches
‘1’
and shows
‘CAL 2’
and alert sounds.
3. Rotate the device 180° on the flat surface and press the
button again. The countdown
screen will begin. Wait until countdown reaches
‘1’
and shows
‘CAL3’
and alert sounds.
4. Now hold the device on a smooth vertical surface (like a door jamb) and press the
button.
The countdown screen will begin. Wait until countdown reaches
‘1’
and shows
‘CAL4’
and
alert sounds.
5. Rotate the device 180° vertically and press the
button. The countdown screen will begin.
Wait until countdown reaches
‘1’
and audible alert beeps. Device is calibrated.
