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. 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.
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 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.
