We want to get you up and running as quickly as possible - but this quick start guide is not a replacement for reading and understanding your
operator’s manual! For complete safety & operating instructions, refer to the operator’s manual included with your tool or scan the QR code.
TROUBLESHOOTING: “Erro” MESSAGE
If this digital level is tilted past approximately 30° forward or
backward (in the non-operational direction), “Erro” will be displayed
on the screen. To return to normal operation, bring the level back to
within 30° of its standard operating position.
CALIBRATION PROCEDURE
Calibration is quick and easy, and is the best way to ensure your
level is reading consistently every time you use it. We recommend
calibrating at the start of each critical job, or when the level is
subjected to drastic changes in temperature (such as going from a
cold car to a warm jobsite).
To calibrate your digital level:
1. Place the level against a wall so that the bubble in the horizontal
vial is in the center of the two indicator marks and the LCD is
facing you.
2. With the level powered ON, press and hold
for three
seconds.
3. The LCD will flash “CAL” while calibration is in progress.
4. If calibration is successful, the LCD will briefly indicate “rdy” and
return to normal operation.
5. If the level fails to calibrate, it will display “Erro” after the
calibration process. If this happens, repeat the calibration
procedure. The most common reasons the level will fail to
calibrate include:
CALIBRATION POSITION
Reference mode temporarily sets the digital level’s current reading to
zero without changing the calibration of the digital level.
Reference mode is ideal to speed up your work in a variety of
scenarios:
1. When taking repeat measurements, such as checking multiple
ramps for ADA compliance, setting a consistent drainage slope, or
adjusting concrete formwork at multiple points, reference mode can
be used to make the desired target “zero”. Then, a reading of “zero”
in reference mode means you have achieved your desired slope.
2. When trying to find the difference between two slopes, reference
mode can eliminate the mathematics and simplify the task. Set the
level on the first slope, enable reference mode, and read your second
slope. The displayed value is the difference between the angles.
3. When trying to find a relative angle on an unlevel surface, such as
setting a blade angle on a saw that is setting on non-level ground,
reference mode can compensate for the angle of the ground. Using
reference mode, you can set the blade angle directly without the
need to compensate for the non-level ground.
To enter reference mode, press
. The digital level will set the
current measurement to “0.0” or “0 in/ft”, and all measured angles
will be relative to this setpoint.
To exit reference mode and return to normal operation, press
.
SETTING A ZERO REFERENCE
• Moving the level during calibration
• The level is too far from its factory zero-point (not leveled)
