INTERPRETING THE BUBBLE DISPLAY
INITIAL SETUP & BASIC OPERATION
1. Power on the remote control by pressing
for 1 second.
2. Power on the sensor by pressing
for 1 second
3. If desired, enable the backlight by holding
for 2 seconds. The
remote control will beep 3 times, and the LCD will display
.
NOTE:
If you hold the button for longer than three seconds, you
will enter calibration mode (5 quick beeps).
4. To change the operating channel, press and hold
for 2
seconds, until 3 beeps are emitted (if volume is enabled). The
LCD will indicate the channel, “A” or “B”. This is useful when
working with multiple detectors in the same area.
5. Toggle audio on/off by holding
until 3 beeps are emitted from
the remote and the LCD indicates
or
.
6. Set the desired sensitivity (displayed in decimals) by pressing
.
The LCD will indicate
0°
,
0.0°
,
0.00°
or
0.000°
.
7. Toggle display units from decimal degrees to degrees/minutes/
seconds by pressing
for 3 seconds. 3 beeps will be emitted
to indicate you have toggled modes and the display will indicate
0.000°
or
0°00’00”
.
8. Toggle display units from mm/m to in/ft or % by pressing
. The
LCD will indicate the set units.
9. Set relative or absolute mode by pressing
. The LCD will
indicate
for relative and
for absolute mode. Absolute mode
will measure angle relative to earth’s gravity, while relative mode
will measure the angle difference between the sensor’s current
and starting position. See “ABSOLUTE VS. RELATIVE MODE”.
10. Choose your displayed axes by pressing
. The LCD will display
both X & Y axes, X only or Y only.
11. When all parameters are set and you are ready to begin taking
measurements, press
. The green LED will illuminate, and the
level will begin measuring.
12. When finished, press
to exit measurement mode, press
to
power off the remote and press
to power off the sensor.

The remote control features a digital bubble display to visually help
you locate zero quickly and easily. A few examples of virtual bubble
displays are shown below to illustrate how to interpret the reading:
Absolute mode measures angle with respect to gravity. Relative
mode measures with respect to the initial starting angle when
measurements are first initiated.
Use absolute mode when leveling equipment to ensure it is truly
level. In many applications, this is the best way to ensure vibration
and wear and tear are minimized. In most applications, this will be
the desired way to use this digital level.
Use relative mode when aligning two pieces of equipment or when
compensating for another surface that is not level. For example, if
leveling a fixture on a milling machine, the milling machine’s table
may not be perfectly level with respect to gravity because it may be
sitting on an uneven floor. Relative mode can be used to set the zero
point to the angle of the table, and the fixture measurements will be
relative to the table.
