POWER BUTTON AND LCD DISPLAY
PLUMB cont. (Fig. 5)
Press the Power button to turn the LCD display screen on. When the screen first comes
on, the temperature is displayed in Fahrenheit for about 2 seconds, to indicate if level is
being used in optimum operating temperature range. The current angle of the level is
then displayed, and a picture of that angle is shown either above or below the line for
true level (see Fig. 2). An arrow on the display indicates if the level has to be moved up
or down. True level is reached when the two lines are together and the angle shows 0o
(see Fig. 3). Turn off by pressing and holding the button in for about 2 seconds. If not
used for 5 minutes the level automatically turns off. The LCD display is large and easy
to read. When the level is turned upside down, the LCD screen senses and changes
to read correctly in the inverted position.
The LCD display shows the surface with the level on it as a line, and true plumb as
another line either to the left or right of the line for plumb, and the degree to with the
surface is off, with an arrow showing whether to move the surface to the left
or right. If the beeper button is on, the level will beep when true plumb or 90o is reached.
Fig. 6
TO USE THE LEVEL FOR HORIZONTAL AND PLUMB MEASUREMENTS
Horizontal and Plumb measurements can use both the bubble vial and the
LCD readout features.
HORIZONTAL
Use the level on horizontal surfaces to true them up. The level's bubble vials will show
when you have the surface level. The bubbles will be exactly in between the marks
on the vial.
Once the Power button is turned on, lay the level on the surface you want to level.
The LCD display will show the surface you are measuring as a line either above
or below the true level line, and the degree to which the surface is off, with
an arrow showing whether the surface should be raised or lowered in order
to be leveled.
The LCD display also gives the degree to which the
surface is off. To level, move the surface with the
level on it until the two lines on the readout match
and the readout says 0o for the angle (Fig. 3).
If the beeper is activated, the beeper will
sound when the level is at level.
PITCH (Fig. 6)
The digital laser level can be used to measure the pitch of a roof. It measures the pitch
in inches of rise per foot of run. Push the conversion button to change angle to pitch.
The pitch will be read as inches per foot in 1/8-in. increments, with a + or a - sign to
indicate if the pitch is above or below the desired measurement.
Fig. 7
PLUMB (Fig. 5)
To find the plumb of a work surface, lay the digital level
against the vertical surface, with the plumb bubble vial at
the top. The surface will be at true plumb when the bubble
is positioned exactly between the marks on the vial.
ANGLE (Fig. 7 )
Fig. 5
10
The digital laser level measures any angle in degrees with up to 0.1o accuracy.
This can be used to find the necessary angle for many surfaces, and when
the conversion button is pushed to display angle, will tell you the angle and which way
it is off of true level. If the beeper button is turned on, the level will beep at 0o angle.
