Re-Leveling
If the LMPL20 is moved from its level position, the LMPL20 will re-level. The leveling feature of the laser is
independent of the Grade and Line Position Settings.
Plumb
1. On a flat horizontal surface place the LMPL20 in its normal operation position.
2. The LMPL20 has a Plumb LED located at the top of the LMPL20 (See Figure 2 #9). This led is
always on when the LMPL20 is powered on.
Grade
The Main Screen displays the selected grade. The LMPL20 has a grade range capability of +40% to –15%. A
grade setting of zero places the laser output at a level position. Grade can be entered in the following ways
from the Main Screen: (see Fig. 3)
1. Rolling Grade – either pressing the “E1” button or the “E2“ button directly enters grade. Pressing and
releasing either button will increment or decrement the grade setting by one. Press and holding either
button will gradually increase the speed at which the grade is incremented or decremented.
2. Direct Entry Grade – Pressing the “C” button will select Direct Entry Grade. Once the button is pressed,
the most significant grade number will be highlighted, indicating that the “E1” or “E2” button will either
increment or decrement the selected digit. Pressing the “D1” or “D2” button will allow selecting the
other grade digits. The selected grade will not take effect until either the “C” button is press again, or 5
seconds have passed without a button being pressed.
3. Auto Grade Zero – Pressing the “E1” and “E2” buttons at the same time implements this function. When
both buttons are pressed at the same time, the LMPL20 will go to a zero grade setting.
REMOTE: Grade can be entered in the same manner by using the RC20 Remote Control. (See Fig. 15)
Note: If the Lock has been turned on, Grade adjustments cannot be made.
Line Position
(See Fig. 3)
The LMPL20 ‘s laser line position can be adjusted ±15% from center. The Line Position can be adjusted from the
Main Screen by pressing the “D1” or the “D2” buttons. Pressing and releasing either button will make a small
adjustment. Pressing and holding either button will gradually increase the speed at which the line position is
adjusted. Pressing the “D1” or the “D2” buttons at the same time implements the Auto Line Position Function,
which positions the line position back to center. The Line Position Icon on the Main Screen indicates the
current position of the laser line. Press and hold both D1 and D2 buttons for three seconds to center the
line control.
REMOTE: Line Position can be entered in the same manner by using the RC20 Remote Control.
Note: When adjusting line position, the remote will communicate to the Pipe Laser with both RF and Infrared for buried
pipe applications.
Note: If the Lock has been turned on, Line Position adjustments cannot be made.
Lock
The Lock feature allows disabling grade and line position adjustments. Pressing the “F” button toggles the lock
between ON and OFF. The Lock Icon on the Main Screen indicates whether the Lock is ON or OFF.
