NWI NRL800X User manual

SAFETY
The instrument is not to be operated for any purpose other than what it is designed for as described in this
manual. Use of the controls, adjustments or performance of procedures other than those specified herein
may result in ha ardous laser exposure. It is the user’s complete responsibility to follow the instructions in
the manual.
• The Laser output information is displayed on the warning label. Do not remove safety labels from the instrument.
• Do not look straight at the laser beam. Set up the instrument in a way that prevents laser beam from shooting
into people’s eyes.
• Do not disassemble the instrument or attempt to perform any internal servicing. Repairs and servicing are to be
performed only by authorized service centers.
• Do not operate or calibrate the unit in any other way or use any other tools or procedures different than
described in this manual.

3. SETTING UP INSTRUMENT
1 Hori ontal Applications
You may set your NRL800X laser unit up on a tripod, hang it up on a wall with a wall mount, (a NUCB05 wall mount,
sold separately), or simply set it on a solid surface.
2. Vertical Applications
With the vertical bracket provided (or NUCB05 wall mount, sold separately), set the instrument on a tripod or solid surface.
Instrument should be set approximately level within ±5°.

4. OPERATION
The NRL800X is a true Grade Laser with capabilities for general construction, roadway and landscaping applications.
lease refer to the (+) Upgrade Decal when doing grade applications.
1. Automatic leveling
ress the power button. The power indicator will be on and automatic leveling will begin. If the power indicator blinks, it means the
battery level is low.
When instrument completes automatic leveling, the rotating head will start rotating and solid laser beam will be emitted.
If the instrument is set outside of its automatic leveling range (±5°), there will be an alarm beep. Turn off the instrument and set up the
instrument again within this range.
2. Grade Setting: lease refer to the (+) Upgrade Decal when doing grade applications
Hori ontal applications: With the NRL800X grade laser, you can directly dial in the grade value you desire and the unit will
automatically set up the grade in the X direction.
(1) Adjust your unit so that the X direction (X marked on upper body of your instrument) is aligned to the direction where the
grade is to be set.
(2) ress the power button and the instrument LCD panel will display “LEVEL”.
(3) ress the button twice and the unit enters into the grade setting
mode. The Slope light will be on and panel will display
“X +0.000%”, with the cursor blinking at “ + ”. ress the or the button to change it between “ + ” or “ -
“ based on your setting need.
(4) ress the button to move the cursor to the digit you want to
change and press the or the buttons to change the value of the digit between 0 and 9.
(5) When the setting is complete and the cursor on the panel stops blinking,
the unit will start to find the grade you have set.
(6) If you want to clear your input, press the and the buttons
at the same time and the panel displays “X +0.000%”.
(7) ress the button to exit the grade-setting mode and return to automatic leveling mode.
Note:
(1) In the Grade setting mode, you can still select rotating, scan or point.

4
Vertical application: Grade setting mode can be used to set the directions of the beam.
(1) After the unit has been set on its vertical mount (in its lay down position) and it has completed automatic leveling, press
the button twice. The slope indicator will be on, and the panel displays “VERTICAL”.
(2) ress the or the buttons to move the beam to your left or right.
(3) ress the button again to exit.
3. HOLD Function
(1) After the unit finds its leveling position, press the button once and the unit will not make any further automatic leveling, but
hold the established level. CAUTION: When the unit is in the HOLD mode, it will not automatically level even if it is bumped.
(2) ress the button again, and the unit returns to the automatic leveling mode.
4 Height of Instrument Protection
(1) By pressing the button twice, the unit will enter into the height of instrument protection mode and 3 indicators will light up. In
this mode, if the instrument is bumped, it will stop rotating and the 3 indicators as well as the laser beam will blink, warning you
that the height of instrument may have been changed.
(2) ress this button again to exit.
5 Battery
The NRL800X grade laser is equipped with rechargeable batteries and a charger. The charging receptacle is located on the battery
pack.
When the charging starts, the red charging light is on, indicating charging is in process. When the green charging light is on, it
indicates charging is completed.
Note:
(1) It takes about 4 hours to fully charge the batteries.
(2) Rechargeable batteries can be charged while the instrument is in operation.
(3) Batteries should be removed from the instrument when the instrument is not being used for an extended period of time.
(4) For a new battery or a battery not used for a long time, it is necessary to carry out 3 to 5 complete discharging/charging cycles and the
charging time must be 4 hours at least each time. This will help extend the battery life capacity.
6 Remote Control
The NRL800X grade laser can be operated by the infrared remote control. The receiver windows are located around the base of the
unit.

5. CHECKING CALIBRATION
ALTHOUGH EACH INSTRUMENT IS CALIBRATED BEFORE SHI ING FROM NWI, IT IS THE USER’S RES ONSIBILITY TO
CHECK THE CALIBRATION OF THE INSTRUMENT BEFORE USE TO AVOID COSTLY MISTAKES.
1 Checking Hori ontal Calibration
(1) Set up the instrument at about 30 meters from a wall (or a grade rod), with the X mark facing the direction of the wall (or grade
rod).
(2) Turn the power on and let the instrument find its level. Find the laser line on the wall and mark it h1. If you have difficulty seeing
the laser line, a laser detector can be used.
(3) Rotate your instrument 180 degrees with (the other) X facing the same wall or grade rod. Find the laser line and mark it h2.
(4) The height different between h1 and h2 should be within 4 mm.
(5) Check the Y directions with the same process.
(6) If the height difference between h1 and h2 is larger than 4 mm, the instrument needs to be sent to an authorized service center
for calibration. Call NWI at 1-888-247-1960 for a service center near you.
2. Checking Calibration of Plummet
(1) Set up the instrument between 2
walls (or 2 grade rods) about 30m
from each other. First set it closer to
one wall than the other as shown
below (fig a).
(2) Lay down the instrument as shown.
ress the ower button and the
instrument will find its level position.
Mark the laser position on the wall
as hA and hB.
(3) Then re-set the instrument to be
closer to the other wall as shown
below (fig b), repeat step (2) and mark the
points as hA1 and hB1.
∆1=hA - hB; ∆2= hA1 - hB1. The difference
between ∆1 and ∆2 should be within 8 mm. If it is
not, the instrument needs to be sent to an authorized
service center for calibration. Call NWI at
1-888-247-1960 for a service center near you.
