POWER BUTTON AND LCD DISPLAY
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
0 °
(see Fig. % 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,
TO USE THE
LEVEL
FOR
HORIZONTAL
AND
PLUMB
MEASUREIVIENTS
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 vialo
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 0 °
for the angle (Fig.. 3).
If the beeper
is activated,
the beeper
will sound
when the level is at level
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.
